Lombok Changelog

v1.18.24 "Edgy Guinea Pig"

  • FEATURE: @ToString has an annotation parameter called onlyExplicitlyIncluded. There's now a config key lombok.toString.onlyExplicitlyIncluded to set this property as well. Issue #2849.
  • FEATURE: Turning a field named uShape into a getter is tricky: getUShape or getuShape? The community is split on which style to use. Lombok does getUShape, but if you prefer the getuShape style, add to lombok.config: lombok.accessors.capitalization = beanspec. Issue #2693 Pull Request #2996. Thanks @YonathanSherwin!
  • BUGFIX: Various save actions and refactor scripts in eclipse work better. Issue #2995 Issue #1309 Issue #2985 Issue #2509
  • BUGFIX: Eclipse projects using the jasperreports-plugin will now compile Issue #1036
  • SECURITY: A widely reported security issue with log4j2 (CVE-2021-44228) has absolutely no effect on either lombok itself nor does usage of lombok on its own, or even the usage of lombok's @Log4j2, cause any issues whatsoever: You have to ship your own log4j2 dependency in your app - update that to 2.17 or otherwise mitigate this issue (see the CVE page). To avoid unneccessary warnings from dependency checkers, our dep on log4j2, which is used solely for testing, isn't shipped by us, and cannot be exploited in any way, has been updated to 2.17.0. Issue #3063

v1.18.22 (October 6th, 2021)

  • PLATFORM: JDK17 support added. Issue #2898.
  • FEATURE: Added the @StandardException feature. Pull Request #2702.
  • IMPROBABLE BREAKING CHANGE: If the underlying compiler and --release / --source option is 10 or higher, lombok's val is now replaced by final var. That means compound declarations such as val x = 10, y = 12; now fail (lombok's old val implementation supported it, javac's var does not), but IDE support in particular is more reliable. We decided it was worth the tradeoff.
  • BUGFIX: Syntax highlighting in VSCode now works reliably when using lombok. Issue #2950.
  • BUGFIX: Eclipse's organize imports feature would sometimes remove your lombok.val import. Issue #2972.

v1.18.20 (April 2nd, 2021)

  • PLATFORM: JDK16 support added. Issue #2681.
  • PLATFORM: All lombok features updated to act in a sane fashion with JDK16's record feature. In particular, you can annotate record components with @NonNull to have lombok add null checks to your compact constructor (which will be created if need be).
  • BUGFIX: Trying to use a lambda expression as parameter to an @ExtensionMethod did not work. Issue #2741. (by @Rawi01).
  • BUGFIX: @SuperBuilder with an existing constructor caused issues in eclipse. Issue #2704. (by @JanRieke).
  • BUGFIX: Using @SuperBuilder with a handwritten builder class caused issues. Issue #2701. (by @JanRieke).
  • BUGFIX: Lombok interacts properly with the new save actions in eclipse 2021-03.
  • POTENTIAL BUGFIX: lombok + errorprone could cause IllegalArgumentException if using the MissingSummary bug pattern. Issue #2730.

v1.18.18 (January 28th, 2021)

  • BUGFIX: Various tools using ecj under the hood (including intellij) could cause corrupt class files to be generated. PR #2637, lombok-intellij-plugin issue #969.
  • BUGFIX: Netbeans would not work with 1.18.16 anymore. Issue #2612.
  • BUGFIX: @ExtensionMethod support in ecj improved when generics are involved. Issue #2648, PR #2658 thanks to @Rawi01.
  • PLATFORM: using lombok.config files when compiling with sbt 1.4 now works again. Issue #2645

v1.18.16 (October 15th, 2020)

  • BUGFIX: Version 1.18.14 could not be installed in Eclipse, it would break Eclipse.
  • BREAKING CHANGE: mapstruct users should now add a dependency to lombok-mapstruct-binding. This solves compiling modules with lombok (and mapstruct).
  • IMPROBABLE BREAKING CHANGE: The generated hashcode has changed for classes that include both primitive fields and reference fields.
  • FEATURE: Similar to @Builder, you can now configure a @SuperBuilder's 'setter' prefixes via @SuperBuilder(setterPrefix = "set") for example. We still discourage doing this. Pull Request #2357.
  • FEATURE: If using @Synchronized("lockVar"), if lockVar is referring to a static field, the code lombok generates no longer causes a warning about accessing a static entity incorrectly. Issue #678
  • FEATURE: @Jacksonized on a @Builder or @SuperBuilder will configure Jackson to use this builder when deserializing. Pull Request #2387 thanks to @JanRieke. @Jacksonized documentation.
  • FEATURE: The checkerframework support has been updated; the relevant annotations were renamed in checkerframework's APIs, lombok now generates the annotations according to their current API names.
  • FEATURE: Add option to cache hashCode via @EqualsAndHashCode(cacheStrategy = EqualsAndHashCode.CacheStrategy.LAZY). Issue #784 Pull Request #2513 thanks to @andrebrait.
  • PLATFORM: Added support for compiling projects with OpenJ9 Pull Request #2437
  • PLATFORM: Improved support for recent JVM/javac versions (14 and 15) and new language features.
  • PERFORMANCE: Several performance improvements during parsing/compilation, both using javac and Eclipse. Thanks @Rawi01!
  • PERFORMANCE: The generated equals method will first compare primitives, then primitive wrappers and then reference fields. Manual re-ordering is possible using @Include(rank=n). Pull Request #2485, Issue #1543
  • BUGFIX: Delombok prints the first this parameter. Issue #2444
  • BUGFIX: Using val in combination with values whose generics include wildcards that reference themselves would cause a StackOverflowError in javac. Issue #2358.
  • BUGFIX: Using @SuperBuilder on a class that has some fairly convoluted generics usage would fail with 'Wrong number of type arguments'. Issue #2359 Pull Request #2362
  • BUGFIX: Various lombok annotations on classes nested inside enums or interfaces would cause errors in eclipse. Issue #2369
  • BUGFIX: Trying to add @ExtensionMethods with exactly 2 arguments would fail in eclipse. Issue #1441 Pull Request #2376 thanks to @Rawi01.
  • BUGFIX: Javac sets incorrect annotated type on with methods. Issue #2463

v1.18.14 (October 8th, 2020)

  • Don't use this version. It is broken. Changes are listed under 1.18.16

v1.18.12 (February 1st, 2020)

  • PLATFORM: Support for JDK13 (including yield in switch expressions, as well as delombok having a nicer style for arrow-style switch blocks, and text blocks).
  • PLATFORM: Support for JDK14 (including pattern match instanceof expressions).
  • FEATURE: In lombok.config it is possible to import other config files, even from a .zip or .jar.
  • FEATURE: You can now configure a builder's 'setter' prefixes via @Builder(setterPrefix = "set") for example. We discourage doing this, but if some library you use requires them, have at it. Pull Request #2174, Issue #1805.
  • FEATURE: If you use @Builder's @Singular, a plural form is also generated, which has the effect of adding all elements in the passed collection. If you pass a null reference, this would result in a message-less NullPointerException. Now, it results in that exception but with a useful message attached (uses the same config as @NonNull), or alternatively via a parameter on @Singular, you can choose to ignore such a call (add nothing, return immediately); this can be useful when deserializing (e.g. Jackson JSON) and JPA/Hibernate code. Issue #2221. singular documentation.
  • FEATURE: Tired of being unable to use @javax.annotation.ParametersAreNonnullByDefault or @org.eclipse.jdt.annotation.NonNullByDefault because then the equals method that lombok generates isn't valid? Fret no more; lombok can now add nullity annotations where relevant. Set the flavour of nullity annotation you prefer in your lombok.config. Applies to the return value of toString, withX, chainable setX, static constructors, build, builder, etcetera, and the parameter of equals, canEqual, and the plural form of @Singular marked fields for builder classes. Issue #788
  • BUGFIX: If using the sonarlint plugin in eclipse for projects bound to sonarcloud, you now no longer get internal errors on sonarlint processing. Issue #2351
  • BUGFIX: lombok.experimental.Wither has been deprecated (it has been renamed to lombok.With). However, the intent is that lombok still handles the old annotation in case you haven't updated your lombok dep yet. However, only a star import on lombok.experimental.* worked; an explicit one would cause lombok to not generate any with method. Issue #2235
  • BUGFIX: Referring to an inner class inside the generics on a class marked with @SuperBuilder would cause the error wrong number of type arguments; required 3 Issue #2262; fixed by github user @Lekanich - thank you!
  • BUGFIX: Some of the code generated by @Builder did not include this. prefixes when accessing fields. While semantically it didn't matter, if you use the 'add this prefix for field accesses' save action in eclipse, the save action would break. Issue #2327
  • BUGFIX: When lombok copies javadoc from fields to relevant methods, it should generate an appropriate @return this line if lombok copies the javadoc to a generated setter that is chainable (returns itself). It didn't do that when generating the 'setters' in a @Builder. Lombok also didn't generate an appropriate @return item for @With methods. The javadoc has also been updated slightly (the this reference in the javadoc is now rendered in a code tag).Issue #2323
  • IMPROBABLE BREAKING CHANGE: Lombok now generates qualified types (so, Outer.Inner instead of just Inner) in most type signatures that it generates; this should avoid exotic scenarios where the types lombok puts in signatures end up referring to unintended other types, which can occur if your class implements an interface that itself defines a type with the same name as one defined in your source file. I told you it was exotic. Thanks to Hunter Anderson for doing some preliminary work on this change. Issue #2268
  • IMPROBABLE BREAKING CHANGE: Running java -jar lombok.jar config -v <files> no longer shows which files do not mention the specified keys. Use --non-mentioned or -n to show them anyway.

v1.18.10 (September 10th, 2019)

  • PROMOTION: @Wither has been promoted to the main package, renamed to @With. Otherwise, no changes have been made to the annotation. The old experimental annotation will remain for a few versions as a deprecated annotation. If you had lombok.config configuration for this annotation, the configuration keys for this feature have been renamed.
  • FEATURE: You can now configure a custom logger framework using the new @CustomLog annotation in combination with the lombok.log.custom.declaration configuration key. See the log documentation for more information. Pullrequest #2086 with thanks to Adam Juraszek.
  • ENHANCEMENT: Thanks to Mark Haynes, the staticConstructor will now also be generated if a (private) constructor already exists. Issue #2100
  • ENHANCEMENT: val is now capable of decoding the type of convoluted expressions (particularly if the right hand side involves lambdas and conditional (ternary) expressions). Pull Request #2109 with thanks to Alexander Bulgakov.
  • ENHANCEMENT: You can now configure the generated builder class name via the config system, using key lombok.builder.className. See the Builder documentation and SuperBuilder documentation
  • ENHANCEMENT: If you mix up eclipse's non-null support, such as @NonNullByDefault, with lombok's @NonNull, you get a bunch of warnings about dead code that are inappropriate. These warnings are now suppressed, thanks to a contribution from Till Brychcy! Pull Request #2155
  • ENHANCEMENT: @NonNull can now also generate checks using jdk's Objects.requireNonNull or Guava's Preconditions.checkNotNull. Issue #1197
  • EXPERIMENT: Lombok is working together with checkerframework to enable detection of improper builder use (such as forgetting to set a mandatory property prior to calling build()). This experiment can be turned on by adding checkerframework = true to your lombok.config file.
  • BUGFIX: Using @JsonProperty or @JsonValue on a field in combination with @Setter or @Data would sometimes throw a ClassCastException during compilation. Issue #2156
  • BUGFIX: Delombok would turn something like List<byte[]>... in a method parameter to List<byte...>... Issue #2140
  • BUGFIX: Javac would generate the wrong equals and hashCode if a type-use annotation was put on an array type field Issue #2165
  • BUGFIX: Eclipse 2019-06 + JDK-12 compatibility + an @Singular builder entry would produce a cascade of error dialogs. Issue #2169
  • BUGFIX: Javac would throw a NullPointerException if the package-info.java did not contain a package declaration. Issue #2184
  • BUGFIX: Javac sets incorrect annotated type on constructor, getter and setter. Issue #2189
  • IMPROBABLE BREAKING CHANGE: Stricter validation of configuration keys dealing with identifiers and types (lombok.log.fieldName, lombok.fieldNameConstants.innerTypeName, lombok.copyableAnnotations).
  • IMPROBABLE BREAKING CHANGE: The fields generated inside builders for fields with defaults (with @Builder on a class with fields marked @Default) now have $value as the name; direct manipulation of these fields is not advised because there is an associated $set variable that also needs to be taken into account. Issue #2115

v1.18.8 (May 7th, 2019)

  • FEATURE: You can now configure @FieldNameConstants to CONSTANT_CASE the generated constants, using a lombok.config option. See the FieldNameConstants documentation. Issue #2092.
  • FEATURE: You can now suppress generation of the builder method when using @Builder; usually because you're only interested in the toBuilder method. As a convenience we won't emit warnings about missing @Builder.Default annotations when you do this. Issue #2046
  • FEATURE: You can now change the access modifier of generated builder classes. Issue #2083.
  • FEATURE: When using @NonNull, or any other annotation that would result in a null-check, you can configure to generate an assert statement instead. Issue #2078.
  • FEATURE: Lombok now knows exactly how to treat @com.fasterxml.jackson.annotation.JsonProperty and will copy it to the right places for example when making builders. Issue #1961 Issue #1981
  • PLATFORM: A few lombok features (most notably delombok) failed on JDK12. Issue #2082
  • BUGFIX: var/val on methods that return an intersection type would now work in Eclipse. Issue #1986
  • BUGFIX: Fix for java6 regression if a field has javadoc. Issue #2066
  • BUGFIX: Delombok now delomboks java10's own var as var and not as the actual underlying type. Issue #2049
  • BUGFIX: If you use @Builder and manually write the build() method in your builder class, javac would error out instead of deferring to your implementation. Issue #2050 Issue #2061
  • BUGFIX: @SuperBuilder together with @Singular on non-lists would produce an erroneous emptyList call. Issue #2104.
  • IMPROBABLE BREAKING CHANGE: For fields and parameters marked non-null, if the method body starts with an assert statement to ensure the value isn't null, no code to throw an exception will be generated.
  • IMPROBABLE BREAKING CHANGE: When using ecj to compile java code with @Builder or @SuperBuilder in it, and a builder setter method was generated for a @NonNull-marked method, no explicit null check would be present. However, running javac on the exact same file would produce the null check. Now ecj also produces this null check. Issue #2120.
  • IMPROBABLE BREAKING CHANGE: We slightly changed the message of the exception lombok generates to handle @NonNull marked parameters. Issue #2122

v1.18.6 (February 12th, 2019)

  • FEATURE: Javadoc on fields will now also be copied to the Builders' setters. Thanks for the contribution, Emil Lundberg. Issue #2008
  • FEATURE: The @FieldNameConstants feature now allows you to write the inner type by hand and add whatever you like to it; lombok will add the constants to this class. See the updated FieldNameConstants feature page.
  • FEATURE: There is now a lombok.config key to configure @ToString's call super behavior; it's just like @EqualsAndHashCode which has had it for a while now. Issue #1918
  • ENHANCEMENT: The toString generation of enums now contains the name of the enum constant. Issue #1916
  • PLATFORM: Due to changes to switch statements in JDK12, lombok wasn't working with the JDK12 preview. Issue #1888
  • BUGFIX: Using @Delegate in combination @NonNull would give an error in jdk8. Issue #1935
  • BUGFIX: Using the new @FieldNameConstants in eclipse would cause errors in the error log view, and error popups if save actions are turned on. Issue #2024
  • BUGFIX: Since version 1.18.4, the delombok ant task didn't work and errored with a NoClassDefFoundError. Issue #1932
  • BUGFIX: Combining both @Setter and @Wither on the same field, when that field also has javadoc with a --setter-- section or an @param tag, resulted in a race condition where the first handler to get to the field would take that part of the javadoc. This is a step along the way to fixing Issue #1033
  • BUGFIX: Compiling multi-module projects would fail on forcing new rounds. Issue #1723, Issue #1858, Issue #1946, Issue #2028

v1.18.4 (October 30th, 2018)

  • PLATFORM: Support for Eclipse Photon. Issue #1831
  • PLATFORM: Angular IDE is now recognized by the installer Issue #1830
  • PLATFORM: Many improvements for lombok's JDK10/11 support.
  • BREAKING CHANGE: The @FieldNameConstants feature has been completely redesigned. Issue #1774 FieldNameConstants documentation
  • BREAKING CHANGE: Lombok will now always copy specific annotations around (from field to getter, from field to builder 'setter', etcetera): A specific curated list of known annotations where that is the right thing to do (generally, @NonNull style annotations from various libraries), as well as any annotations you explicitly list in the lombok.copyableAnnotations config key in your lombok.config file. Also, lombok is more consistent about copying these annotations. (Previous behaviour: Lombok used to copy any annotation whose simple name was NonNull, Nullable, or CheckForNull). Issue #1570 and Issue #1634
  • FEATURE: Lombok's @NonNull annotation can now be used on type usages (annotation on type usages has been introduced in JDK 8). @Builder's @Singular annotation now properly deals with annotations on the generics type on the collection: @Singular List<@NonNull String> names; now does the right thing.
  • FEATURE: You can now mix @SuperBuilder and toBuilder, and toBuilder no longer throws NullPointerException if a @Singular-marked collection field is null. Issue #1324
  • FEATURE: delombok now supports module paths via the --module-path option, and will automatically add lombok itself to the module path. This should make it possible to delombok your modularized projects. Issue #1848
  • FEATURE: You can pass @args.txt to delombok to read args from the text file; useful if you have really long classpaths you need to pass to delombok. Issue #1795
  • BUGFIX: @NoArgsConstructor(force=true) would try to initialize already initialized final fields in Eclipse. Issue #1829
  • BUGFIX: When using lombok to compile modularized (module-info.java-style) code, if the module name has dots in it, it wouldn't work. Issue #1808
  • BUGFIX: Errors about lombok not reading a module providing org.mapstruct.ap.spi when trying to use lombok in jigsaw-mode on JDK 11. Issue #1806
  • BUGFIX: Fix NetBeans compile on save. Issue #1770
  • BUGFIX: If you manually write your builder class so you can add a few methods of your own, and those methods refer to generated methods, you'd usually run into various bizarre error messages, but only on JDK9/10/11. This one is hard to describe, but we fixed it. Issue #1907

v1.18.2 (July 26th, 2018)

  • BUGFIX: mapstruct + lombok in eclipse should hopefully work again. Issue #1359 and mapstruct issue #1159
  • BUGFIX: Equals and hashCode again exclude transient fields by default. Issue #1724
  • BUGFIX: Eclipse 'organize imports' feature (either explicitly, or if automatically triggered on saving via 'save actions') would remove the import for lombok.var. Issue #1783
  • BUGFIX: Lombok and gradle v4.9 didn't work together; that's been fixed. Issue #1716 and gradle-apt-plugin issue #87
  • FEATURE: You can now make builders for type hierarchies, using the new (experimental) @SuperBuilder annotation. Thanks for the contribution, Jan Rieke. @SuperBuilder documentation
  • FEATURE: @NoArgsConstructor, including forcing one with lombok.config: lombok.noArgsConstructor.extraPrivate=true now take any defaults set with @Builder.Default into account. Issue #1347

v1.18.0 (June 5th, 2018)

  • BREAKING CHANGE: The in 1.16.22 introduced configuration key lombok.noArgsConstructor.extraPrivate is now false by default. Issue #1708
  • BUGFIX: Do not generate a private no-args constructor if that breaks the code. Issue #1703, Issue #1704, Issue #1712
  • BUGFIX: Using boolean parameters in lombok annotations would fail. Issue #1709
  • BUGFIX: Delombok would give an error message. Issue #1705
  • BUGFIX: Eclipse java10 var support didn't work if lombok was installed in your eclipse. Issue #1676
  • FEATURE: Google's Flogger (a.k.a. FluentLogger) is now available via @Flogger. Issue #1697
  • FEATURE: @FieldNameConstants has been extended to support prefixes and suffixes. By default, the generated constants are prefixed with FIELD_. Docs on @FieldNameConstants.

v1.16.22 "Envious Ferret" (May 29th, 2018)

  • FEATURE: Private no-args constructor for @Data and @Value to enable deserialization frameworks (like Jackson) to operate out-of-the-box. Use lombok.noArgsConstructor.extraPrivate = false to disable this behavior.
  • FEATURE: Methods can now be marked for inclusion in toString, equals, and hashCode generation. There is a new mechanism to mark which fields (and now, methods) are to be included or excluded for the generation of these methods: mark the relevant member with for example @ToString.Include or @EqualsAndHashCode.Exclude. ToString documentation EqualsAndHashCode documentation
  • FEATURE: @Getter and @Setter also allow onMethod and onParam when put on a type. Issue #1653
  • FEATURE: @FieldNameConstants is a new feature that generates string constants for your field names. Docs on @FieldNameConstants.
  • PLATFORM: Lombok can be compiled on JDK10, and should run on JDK10. Issue #1693
  • PLATFORM: lombok now counts as an incremental annotation processor for gradle. Should speed up your gradle builds considerably! Issue #1580
  • PLATFORM: Fix for using lombok together with JDK9+'s new module-info.java feature. Issue #985
  • BUGFIX: Solved some issues in eclipse that resulted in error 'A save participant caused problems'. Issue #879
  • BUGFIX: Netbeans on jdk9. Issue #1617
  • BUGFIX: Netbeans < 9. Issue #1555
  • PROMOTION: var has been promoted from experimental to the main package with no changes. The 'old' experimental one is still around but is deprecated, and is an alias for the new main package one. var documentation.
  • OLD-CRUFT: lombok.experimental.Builder and lombok.experimental.Value are deprecated remnants of when these features were still in experimental. They are now removed entirely. If your project is dependent on an older version of lombok which still has those; fret not, lombok still processes these annotations. It just no longer includes them in the jar.

v1.16.20 (January 9th, 2018)

  • PLATFORM: Better support for jdk9 in the new IntelliJ, Netbeans and for Gradle.
  • BREAKING CHANGE: lombok config key lombok.addJavaxGeneratedAnnotation now defaults to false instead of true. Oracle broke this annotation with the release of JDK9, necessitating this breaking change.
  • BREAKING CHANGE: lombok config key lombok.anyConstructor.suppressConstructorProperties is now deprecated and defaults to true, that is, by default lombok no longer automatically generates @ConstructorProperties annotations. New config key lombok.anyConstructor.addConstructorProperties now exists; set it to true if you want the old behavior. Oracle more or less broke this annotation with the release of JDK9, necessitating this breaking change.
  • DEVELOPMENT: Compiling lombok on JDK1.9 is now possible.
  • BUGFIX: The generated hashCode would break the contract if callSuper=true,of={}. Issue #1505
  • BUGFIX: delombok no longer prints the synthetic outer-class parameter. Issue #1521
  • BUGFIX: @Builder.Default now also works when type parameters are present. Issue #1527
  • BUGFIX: @Builder now also works on method with a generified return type. Issue #1420
  • INSTALLER: By default, the lombok installer now inserts an absolute path in eclipse.ini and friends, instead of a relative path. If you want the old behavior, you can use java -jar -Dlombok.installer.fullpath=false lombok.jar.

v1.16.18 (July 3rd, 2017)

  • PLATFORM: JDK9 support much improved since v1.16.16; Issue #985
  • BUGFIX: Lombok now works with Bazel and Error Prone. Issue #1290
  • FEATURE: Lombok has a new website! A few very minor changes to the code to be more consistent with it have been added, mostly to the javadoc.

v1.16.16 "Dancing Elephant" (March 23rd, 2017)

  • FEATURE: @Builder.Default lets you configure default values for your fields when using @Builder. See the Builder feature page for more information. Issue #1201
  • PLATFORM: JDK9 now supported for compilation (delomboking with java9 not yet possible). Note, you'll have to do some command line wrangling. See Issue #985
  • BUGFIX: The onX feature (which lets you add annotations to generated methods) did not work if the annotation you added contained named parameters, and you are compiling with JDK8's javac. We can't fix this (it's a bug in javac), but we have provided an alternate, prettier way to do onX on javac8+. Issue #778 onX documentation
  • BUGFIX: @Data and @Value now respect the configuration for field access when generating equals, hashCode and toString. Issue #1329
  • BUGFIX: @Builder now marks generated builder 'setters' as @Deprecated if the source field is deprecated. Issue #1342
  • CHANGE: @ConstructorProperties will now also be generated for private and package private constructors. This is useful for Jackson Issue #1180

v1.16.14 (February 10th, 2017)

  • FEATURE: Generated classes, methods and fields can now also annotated with @lombok.Generated Issue #1014
  • PLATFORM: Lombok can now be used together with other annotation processors that are looking for lombok-generated methods, but only if lombok is the first annotation processor executed. The most commonly used annotation processor affected by this change is MapStruct; we've worked with the mapstruct team specifically to allow any order. Other annotation processors might follow the framework we've built to make this possible; point the authors of any such processor to us and we'll get it sorted MapStruct issue #510 Lombok issue #973
  • PLATFORM: Eclipse: Refactor script 'rename field' when lombok has also generated getters and/or setters for this field is nicer now Issue #210
  • BUGFIX: Something you never encountered. Issue #1274
  • DEPRECATION: The configuration key lombok.addGeneratedAnnotation is now deprecated, use lombok.addJavaxGeneratedAnnotation instead.

v1.16.12 (December 5th, 2016)

  • FEATURE: var is the mutable sister of val. For now experimental, and opt-in using ALLOW in the flagUsage configuration key. Thanks for the contribution, Bulgakov Alexander.
  • CHANGE: @Value and @FieldDefaults no longer touch static fields Issue #1254
  • BUGFIX: val in lambda expressions now work as expected Issue #911
  • BUGFIX: Getter(lazy=true) now emits an error message when used on a transient field Issue #1236
  • BUGFIX: Annotation Processors that use ecj internally (dagger) no longer give linkage errors Issue #1218
  • PLATFORM: Red Hat JBoss Developer Studio is now correctly identified by the installer Issue #1164
  • BUGFIX: delombok: for-loops with initializers that are not local variables would be generated incorrectly Issue #1076

v1.16.10 (July 15th, 2016)

  • FEATURE: Added support for JBoss logger Issue #1103
  • ENHANCEMENT: Running javac -Xlint:all would generate a warning about unclaimed annotations Issue #1117
  • BUGFIX: Eclipse Mars would sometimes throw a NullPointerException when using @Delegate Issue #913
  • ENHANCEMENT: Add support for older maven-compiler-plugin Issue #1138

v1.16.8 (March 7th, 2016)

  • PLATFORM: Starting jdk9 support: No more error message regarding pid
  • FEATURE: @Builder updates: It now generates clearFieldName() methods if @Singular is used. Issue #967.
  • FEATURE: @Builder updates: The annotation can now be put on instance methods. Issue #63.
  • FEATURE: @Builder updates: @Singular now supports guava's ImmutableTable Issue #937.
  • FEATURE: A lombok.config key can now be used to make your fields final and/or private... everywhere. We'll be monitoring the performance impact of this for a while. We'll touch every source file if you turn these on, and even if you don't, we have to call into the lombok config system for every file.
  • FEATURE: A lombok.config key can now be used to set the default behaviour of @EqualsAndHashCode when generating methods for a class that extends something in regards to calling the superclass implementations of equals and hashCode or not. Issue #965.
  • FEATURE: Putting @Wither on abstract classes now generates something slightly more useful: An abstract wither method. Issue #945.
  • BUGFIX: @Helper used to only be be legal in pretty specific places; now it works just about everywhere.
  • BUGFIX: lambdas with 1 argument that has an explicit type did not pretty print correctly. Issue #972.
  • BUGFIX: When using delombok, a source file with only @NonNull annotations on parameters as lombok feature would not get properly delomboked. Issue #950.
  • BUGFIX: @Delegate in javac would generate arrays instead of varargs parameters. Issue #932.
  • BUGFIX: @Value and @FieldDefaults no longer make uninitialized static fields final. Issue #928.
  • ENHANCEMENT: @Builder.ObtainVia now has @Retention(SOURCE) Issue #986.
  • ENHANCEMENT: Putting @NonNull on a parameter of an abstract method no longer generates a warning, to allow you to use this annotation to document intended behaviour Issue #807.

v1.16.6 (August 18th, 2015)

  • FEATURE: @Helper can be placed on method-local inner classes to make all methods in the class accessible to the rest of the method. Full documentation.
  • FEATURE: @Builder(toBuilder = true) is now available. It produces an instance method that creates a new builder, initialized with all the values of that instance. For more, read the Feature page on Builder.
  • FEATURE: the hashCode() method generated by lombok via @EqualsAndHashCode, @Data, and @Value is now smarter about nulls; they are treated as if they hash to a magic prime instead of 0, which reduces hash collisions.
  • FEATURE: @NoArgsConstructor(force = true) can be used to create no args constructors even if final fields are present.
  • BUGFIX: Parameterized static methods with @Builder would produce compiler errors in javac. Issue #828.
  • BUGFIX: The new annotations-on-types feature introduced in JDK8 did not delombok correctly. Issue #855.
  • PERFORMANCE: the config system caused significant slowdowns in eclipse if the filesystem is very slow (network file system) or has a slow authentication system.
  • BUGFIX: Various quickfixes in Eclipse Mars were broken. Issue #861 Issue #866 Issue #870.

v1.16.4 (April 14th, 2015)

  • BUGFIX: Lombok now works with Eclipse Mars.
  • BUGFIX: @UtilityClass could result in uninitialized static variables if compiled with ecj/eclipse. Issue #839
  • BUGFIX: This version of lombok has a refactored launcher (the one introduced in v1.16.0), which fixes various bugs related to errors in eclipse concerning loading classes, failure to find lombok classes, and errors on ClassLoaders. Probably impacts issues Issue #767 and Issue #826.

v1.16.2 (February 10th, 2015)

  • FEATURE: The config key lombok.extern.findbugs.addSuppressFBWarnings can now be used to add findbugs suppress warnings annotations to all code lombok generates. This addresses feature request Issue #737.
  • FEATURE: New lombok annotation: @UtilityClass, for making utility classes (not instantiable, contains only static 'function' methods). See the feature documentation for more information.
  • BUGFIX: The ant delombok task was broken starting with v1.16.0. Note that the task def class has been changed; taskdef lombok.delombok.ant.Tasks$Delombok instead of the old lombok.delombok.ant.DelombokTask. Issue #810.
  • BUGFIX: val in javac would occasionally fail if used inside inner classes. This is (probably) fixed. Issue #729 and Issue #616.
  • BUGFIX: Starting with v1.16.0, lombok would fail to execute as an executable jar if it was in a path with spaces in it. Issue #812.
  • BUGFIX: v1.16.0 did not work in old eclipse versions (such as eclipse indigo). Issue #818.

v1.16.0 "Candid Duck" (January 26th, 2015)

  • BUGFIX: @ExtensionMethod was broken in Eclipse using java 8. Issue #777, Issue #782
  • BUGFIX: delombok: Using exotic characters in your source files would overzealously backslash-u escape them. Now, all characters are printed unescaped, assuming your chosen encoding can support them. Otherwise, they are escaped. Issue #794
  • PROMOTION: @Builder has graduated from experimental to the main package with a few changes (addition of @Singular, removal of the fluent and chain options). The old one still exists and has been deprecated.
  • FEATURE: @Builder now supports adding the @Singular annotation to any field/parameter that represents a collection, which results in a method in the generated builder that takes in one element of that collection and adds it. Lombok takes care of generating the appropriate code to produce a compacted immutable version of the appropriate type. In this version, java.util collections and guava's ImmutableCollections are supported. See the feature documentation for more information.
  • FEATURE: Added a launcher to the lombok boot process which removes the need for -Xbootclasspath to be in your eclipse.ini file, and removes all non-public API and third party dependencies (such as ASM) from the lombok jar, thus removing them from your IDE's auto complete offerings in any project that uses lombok. For those debugging lombok, the launcher enables hot code replace which makes debugging a lot easier, as previously one was required to shut down the IDE, rebuild the jar, and relaunch. Add -Dshadow.override.lombok=/path/to/lombok/bin to the launch target for hot code replace.

v1.14.8 (September 15th, 2014)

  • PERFORMANCE: The configuration system typically hit the filesystem twice per read configuration key instead of hardly ever. This is a continuation of Issue #717.

v1.14.6 (September 2nd, 2014)

  • BUGFIX: Usage of val would break starting with JDK8 release 1.8.0_20. Issue #766
  • BUGFIX: Depending on your eclipse project setup, releases v1.14.0 through v1.14.4 could noticably slow down your eclipse. Issue #717.

v1.14.4 (July 1st, 2014)

  • BUGFIX: GWT produces errors in handlers on line 1 in any source files that use lombok; this has been fixed. Issue #734
  • BUGFIX-IN-PROGRESS: Many pathfinder issues in eclipse (see the bugfix in progress in v1.14.2) have now been fixed. Issue #717

v1.14.2 (June 10th, 2014)

  • BUGFIX: syntax highlighting in eclipse will become weird and auto-complete may stop working amongst other eclipse features in v1.14.0 (regression from v1.12.6). Issue #723
  • FEATURE: Added @Tolerate; put this annotation on any method or constructor and lombok will skip it when considering whether or not to generate a method or constructor. This is useful if the types of the parameters of your method do not clash with what lombok would generate.
  • FEATURE: Added config key lombok.getter.noIsPrefix, which lets you disable use and generation of isFoo(), instead going with getFoo(), for {@code boolean} fields.
  • BUGFIX: Errors in the eclipse log with IndexOutOfBound: 2 in ASTConverter.convertType. Issue #721
  • BUGFIX-IN-PROGRESS: As yet unknown conditions in eclipse result in lots of IllegalArgumentException in the log with message "Path must include project and resource name". Also, 'invalid URL' or 'URI not absolute' errors can occur when using exotic file system abstractions such as Jazz. These bugs haven't been fixed, but instead of catastrophic failure, warning logs will be emitted instead. Issue #717
  • BUGFIX: mvn builds fail with a 'URI not absolute' exception. Issue #718

v1.14.0 "Branching Cobra" (May 27th, 2014)

  • FEATURE: You can now configure aspects of lombok project wide (or even workspace wide, or just for a single package) via the configuration system. You can configure many things; run java -jar lombok.jar config -gv for the complete list.
  • DEPRECATION: @Delegate has been moved to lombok.experimental.Delegate, and corner cases such as recursive delegation (delegating a type that itself has fields or methods annotated with @Delegate) are now error conditions. See the feature documentation for more information.
  • FEATURE: It is now possible to put annotations, such as @Nullable, on the one parameter of generated equals() methods by specifying the onParam= option on @EqualsAndHashCode, similar to how that feature already exists for @Setter. Issue #709
  • CHANGE: suppressConstructorProperties should now be configured via lombok configuration. Issue #694
  • CHANGE: The canEqual method generated by @EqualsAndHashCode, @Value and @Data is now protected instead of public. Issue #695
  • BUGFIX: Major work on improving support for JDK8, both for javac and eclipse.
  • BUGFIX: Deadlocks would occasionally occur in eclipse when using lazy getters Issue #625
  • BUGFIX: Usage of @SneakyThrows with a javac from JDK8 with -target 1.8 would result in a post compiler error. Issue #690
  • BUGFIX: Switching workspace on some versions of eclipse resulted in a 'duplicate field' error. Issue #701

v1.12.6 (March 6th, 2014)

  • BUGFIX: Deadlocks would occasionally occur in eclipse during project builds, especially if using the gradle plugin. Issue #680
  • PLATFORM: Added support for Eclipse Luna. Issue #644
  • PLATFORM: Initial JDK8 support for eclipse's alpha support in kepler. Issue #632
  • FEATURE: The various @Log annotations now support the topic parameter, which sets the logger's name. The default remains the fully qualified type name of the class itself. Issue #667.
  • BUGFIX: Using lombok with IntelliJ and the IBM JDK would result in NPEs during initialization. Issue #683.
  • BUGFIX: Eclipse quickfix Surround with try/catch block didn't work inside @SneakyThrows annotated methods Issue #511.
  • BUGFIX: Eclipse refactoring Extract Local Variable didn't work inside @SneakyThrows annotated methods Issue #668.
  • BUGFIX: {Netbeans} @SneakyThrows would lead to unused import and break refactorings Issue #544.
  • BUGFIX: Eclipse Organize Imports would generate error: AST must not be null Issue #666.
  • BUGFIX: Copying javadoc to getters / setters / withers would copy non-relevant sections too. Issue #620.
  • ENHANCEMENT: Lombok used to ship with JNA. It added over 800k to the size of lombok.jar and could mess with usage of JNA in your local environment, especially in eclipse. Issue #682
  • DETAIL: {Delombok} Inside enum bodies the delombok formatter didn't respect the emptyLines directive Issue #664.
  • DETAIL: Use smaller primes (<127) for generating hashcodes Issue #660

v1.12.4 (January 15th, 2014)

  • BUGFIX: v1.12.2's delombok turns all operator+assignments into just assignment. Fixed. Issue #633
  • BUGFIX: {Netbeans} v1.12.2 doesn't well with netbeans. Issue #626
  • ENHANCEMENT: Delombok now supports varied options for how it formats the resulting source files. This includes scanning the source for things like the preferred indent. Use option --format-help for more information. Issue #643
  • DETAIL: The primes lombok generates for use in generated hashCode() methods used to be direct copies from Effective Java. It turns out these particular primes are used so much, they tend to be a bit more collision-prone, so we switched them. Now, '277' is used instead of '31'. The primes for booleans have also been changed. Issue #660

v1.12.2 (October 10th, 2013)

  • PLATFORM: Initial JDK8 support, without affecting existing support for JDK6 and 7. Issue #524. While lombok will now work on JDK8 / javac8, and netbeans 7.4 and up, lombok does not (yet) support new language features introduced with java8, such as lambda expressions. Support for these features will be added in a future version.
  • PLATFORM: Running javac on IBM J9 VM would cause NullPointerExceptions when compiling with lombok. These issues should be fixed. Issue #589.
  • CHANGE: [JDK8-related] The canonical way to write onMethod / onParameter / onConstructor annotation now uses a double underscore instead of a single underscore, so, now, the proper way to use this feature is @RequiredArgsConstructor(onConstructor=@__(@Inject)). The old way (single underscore) still works, but generates warnings on javac 8.
  • BUGFIX: Using @NonNull on an abstract method used to cause exceptions during compilation. Issue #594.
  • BUGFIX: Using @NonNull on methods that also have @SneakyThrows or @Synchronized caused arbitrary behaviour. Issue #623.
  • GERMANY: Major version bumped from 0 to 1, because allegedly this is important. Rest assured, this change is nevertheless backwards compatible.

v0.12.0 "Angry Butterfly" (July 16th, 2013)

  • FEATURE: javadoc on fields will now be copied to generated getters / setters / withers. There are ways to specify separate javadoc for the field, the setter, and the getter, and @param and @return are handled appropriately. Addresses feature request Issue #132. @Getter and @Setter documentation. @Wither documentation.
  • CHANGE: The desugaring of @Getter(lazy=true) is now less object creation intensive. Documentation has been updated to reflect what the new desugaring looks like. @Getter(lazy=true) documentation.
  • PROMOTION: @Value has been promoted from experimental to the main package with no changes. The 'old' experimental one is still around but is deprecated, and is an alias for the new main package one. @Value documentation.
  • FEATURE: {Experimental} @Builder support. One of our earliest feature request issues, Issue #89, has finally been addressed. @Builder documentation.
  • FEATURE: @NonNull on a method or constructor parameter now generates a null-check statement at the start of your method. This nullcheck will throw a NullPointerException with the name of the parameter as the message. Issue #549
  • BUGFIX: Usage of Lombok.sneakyThrow() or @SneakyThrows would sometimes result in invalid classes (classes which fail with VerifyError). Issue #543
  • BUGFIX: Using val in try-with-resources did not work for javac. Issue #555
  • BUGFIX: When using @Data, warnings are not generated if certain aspects are not generated because you wrote explicit versions of them. However, this gets confusing with equals / hashCode / canEqual, as nothing is generated if any one of those methods is present. Now, if one of equals or hashCode is present but not the other one (or canEqual is present but equals and/or hashCode is missing), a warning is emitted to explain that lombok will not generate any of the equals / hashCode methods, and that you should either write them all yourself or remove them all. Issue #548
  • BUGFIX: Possibly fixed a race condition in patcher Issue #566.

v0.11.8 (April 23rd, 2013)

  • FEATURE: Major performance improvements in eclipse by profiling the project clean process.
  • CHANGE: {Experimental} The experimental @Value feature no longer implies the also experimental @Wither. If you like your @Value classes to make withers, add @Wither to the class right next to @Value.
  • FEATURE: {Experimental} Reintroduced onMethod, onConstructor and onParam to @Getter, @Setter, @Wither, and @XArgsConstructor. These parameters allow you to add annotations to the methods/constructors that lombok will generate. This is a workaround feature: The stability of the feature on future versions of javac is not guaranteed, and if a better way to implement this feature is found, this feature's current incarnation will be removed without a reasonable period of deprecation. Documentation on the onX feature
  • FEATURE: Added support for Log4j v2.0 via @Log4j2 Issue #505
  • ENHANCEMENT: The Lombok installer can now find and install lombok into JBoss Developer Studio. The installer will now also look for eclipse and eclipse variants in your home directory. Issue #507
  • BUGFIX: @ExtensionMethods no longer causes VerifyError exceptions when running eclipse-compiled code if extension methods are called on expressions which are method calls whose return type is a type variable. For example, someList.get(i).extensionMethod() would fail that way. Issue #509
  • BUGFIX: java 7's try-with-resources statement did not delombok correctly. Issue #532

v0.11.6 (October 30th, 2012)

  • FEATURE: Lombok can be disabled entirely for any given compile run by using JVM switch -Dlombok.disable. This might be useful for code style checkers and such.
  • FEATURE: Added support for Slf4j extended logger Issue #494
  • BUGFIX: {Delombok} Running delombok has been causing VerifyError errors when used with javac 1.7 since 0.11.0. Issue #495
  • BUGFIX: A conflict between lombok and certain eclipse plugins would result in NullPointerExceptions in the log when using @Delegate.
  • BUGFIX: NullPointerException in lombok.&#8203;javac.&#8203;handlers.&#8203;JavacHandlerUtil.&#8203;upToTypeNode&#8203;(JavacHandlerUtil.java:978) when compiling with @ExtensionMethod in javac and generated constructors are involved. Issue #496
  • BUGFIX: @Deprecated on a field that gets a generated setter in eclipse would result in IllegalArgumentException, which you wouldn't see unless you have the error log open. If you have save actions defined, you'd get a popup box with the exception. Now fixed. Issue #481

v0.11.4 (August 13th, 2012)

  • FEATURE: {Experimental} @Value, @Wither and @FieldDefaults are now available. These are a lot like @Data but geared towards immutable classes. Documentation on @Value, Documentation on @Wither and Documentation on @FieldDefaults.
  • BUGFIX: Eclipse would throw an OOME if using @ExtensionMethod. Issue #463
  • BUGFIX: {Netbeans} @Cleanup and @Synchronized cause far fewer issues in the netbeans editor. Issue #466
  • BUGFIX: {Installer} Erroneous messages about the installer complaining about needing root access when installing or removing lombok from eclipse installs has been fixed. The installer edge of this problem was actually already fixed in v0.11.2. Issue #436
  • BUGFIX: @ExtensionMethod had all sorts of issues in javac. Issue #472
  • BUGFIX: Generating static constructors with javac when you have fields with generics, i.e. Class<T>, caused errors. Issue #469
  • BUGFIX: Minor @ExtensionMethod issues in eclipse, such as the ability to call extension methods on a super reference which is now no longer possible. Issue #479

v0.11.2 "Dashing Kakapo" (July 3rd, 2012)

  • FEATURE: {Experimental} @ExtensionMethod is now available to add extensions to any type in the form of static methods that take as first parameter an object of that type. Documentation on @ExtensionMethod
  • FEATURE: ONGOING: Fix for using lombok together with gwt-designer.
  • ENHANCEMENT: Small performance enhancements in equals and hashCode. Issue #439
  • BUGFIX: Eclipse would display an error message regarding an invalid super constructor in the wrong location. Issue #409
  • BUGFIX: Eclipse refactor script 'rename method arguments' should work more often with lombok-affected methods.
  • BUGFIX: Using val in an enhanced for loop did not work if the iterable was a raw type.
  • BUGFIX: Using @Getter(lazy=true) when the data type is boolean, int, array, or some other type that requires special treatment for hashCode/equals, now works properly with @Data, @EqualsHashCode and @ToString. Issue #449
  • BUGFIX: SneakyThrows in constructor should not wrap this/super call in try-block Issue #454
  • BUGFIX: Setting breakpoints on code above the first generated method was not possible. Issue #450

v0.11.0 (March 26th, 2012)

  • FEATURE: {Experimental} 'fluent' getters and setters (using just fieldName as methodname instead of getFieldName), setters that return this instead of void, and support for fields with prefixes is introduced with this lombok version. Also, the number of parameters of any existing methods with the same name that lombok would generate are now taken into account; previously if you had any method named setX regardless of how many parameters it has, lombok would avoid generating a setX method. Now lombok generates the method if all present setX methods have a number of parameters other than 1. documentation.
  • FEATURE: The combination of @Delegate and @Getter or @Data will now delegate to the result of a generated getter. Issue #401
  • FEATURE: Developing android apps on eclipse with lombok is now possible by running java -jar lombok.jar publicApi and including the generated jar in your project. Documentation on using lombok for android development.
  • BUGFIX: In NetBeans the generated default constructor would still be generated even if Lombok also generated constructors. Issue #399
  • BUGFIX: Some classes that contain @SneakyThrows would not compile (throw ClassFormatError). Issue #412
  • BUGFIX: delombok: When @Delegate would generate a method with type parameters of the type T extends package.Class, a dot would be prepended to the type name. Issue #414
  • BUGFIX: @Getter and @Setter now generate deprecated methods for deprecated fields. Fixes Issue #415
  • BUGFIX: @Delegate would not generate @Deprecated on methods marked deprecated in javadoc. Fixes Issue #421
  • BUGFIX: Using val with a type like Outer<TypeArgs>.Inner now works. Issue #416
  • BUGFIX: @Getter(lazy=true) where the variable type is a primitive and the initializing expression is of a different primitive type that would type coerce implicitly, i.e. ints can be assigned to longs without a cast, didn't work before. Issue #418
  • BUGFIX: val is no longer legal inside basic for loops (the old kind, not the foreach kind). These variables should rarely be final, and in practice it wasn't possible to delombok this code properly. Issue #419
  • BUGFIX: PrettyCommentsPrinter now prints default clause of annotation methods. Fixes Issue #423

v0.10.8 (January 19th, 2012)

  • FEATURE: @Delegate can now be used on a no-argument method, which works similarly to adding it to fields. See documentation.
  • BUGFIX: Eclipse refactoring Extract Interface was broken when using lombok annotation to generate methods. Issue #159
  • BUGFIX: Eclipse action Sort Members was broken when using lombok annotations to generate methods or fields. Issue #338
  • BUGFIX: Eclipse action Refactor/Rename on an inner type was broken when using lombok annotations. Issue #389
  • BUGFIX: 0.10.6 causes ClassNotFoundErrors when using ecj (and thus, play framework, gwt, etc). Issue #393
  • BUGFIX: Eclipse parsing was broken when using lombok annotations with parentheses. Issue #398
  • ENHANCEMENT: Lombok now adds a line to the Eclipse About dialog about itself.

v0.10.6 (December 19th, 2011)

  • PERFORMANCE: Performance issues (memory leaks) when using lombok in netbeans, introduced in 0.10, have been fixed. Issue #315
  • BUGFIX: Eclipse quickfix "Add unimplemented methods" would sometimes insert the new method stubs in strange places, especially if @Data was present. Issue #124
  • BUGFIX: Eclipse quickfix "Assign parameter to new field" would insert it outside the class body if @Data was present. Issue #295
  • BUGFIX: Renaming a @Data-annotated class in eclipse using Alt+Shift+R no longer mangles the data annotation. Issue #359
  • BUGFIX: Using save action 'Use this qualifier for field accesses, only if necessary' did not work together with @Data in certain cases. Issue #374
  • BUGFIX: Organize imports, either run manually or as save action, would throw an exception. Issue #381
  • BUGFIX: Extracted constants would be placed outside the class body when a logging annotation was present. Issue #388

v0.10.4 (November 21st, 2011)

  • BUGFIX: Using the log field from @Log, etc, now works in static initializers. Issue #368
  • BUGFIX: Auto-formatting code containing lombok on eclipse, even via an auto-save action, now works. Issue #163
  • BUGFIX: Letting eclipse generate various methods when a lombok annotation is present now works. Issue #211
  • BUGFIX: Renaming a @Data-annotated class in eclipse no longer mangles the data annotation. Issue #359
  • BUGFIX: Eclipse save action Add final modifier to private fields no longer adds final keyword to @Setter fields. Issue #336
  • BUGFIX: Mixing labels and lombok.val would cause NPEs in javac. Issue #372
  • BUGFIX: Writing lombok.val out in full (vs. using an import statement) did not work in eclipse. Issue #373

v0.10.2 (November 1st, 2011)

  • BUGFIX: Delombok will no longer jumble up comments from different files when using -sourcepath option. Issue #357
  • BUGFIX: Turns out treating @NotNull as an annotation that indicates lombok should generate nullcheck guards causes all sorts of problems. This has been removed again, and documentation has been updated to reflect this. Issue #360
  • BUGFIX: @EqualsAndHashCode or @Data did not work on non-static inner classes whose outer class has a type variable. It does now. Issue #362

v0.10.1 (October 3rd, 2011)

  • BUGFIX: @Delegate in eclipse could cause memory leaks in 0.10.0. Issue #337
  • BUGFIX: Annotations on enum values were being deleted by delombok. Issue #342
  • BUGFIX: @AllArgsConstructor was erroneously generating a parameter and an assignment for final variables already assigned in their declaration. Issue #351
  • ENHANCEMENT: @NotNull is now also recognized as an annotation indicating that lombok should generate nullcheck guards in generated constructors and setters. Issue #344

v0.10.0 "Burning Emu" (August 19th, 2011)

  • FEATURE: New annotation: @Delegate. This annotation lets lombok generate delegation methods for a given field. More…
  • FEATURE: Added support for 'val'. Val is an immutable variable that infers its type from the right hand side of the initializing expression. More…
  • FEATURE: Added support for several logging frameworks via the @Log, @Slf4j, etc. annotation. More…
  • FEATURE: Lombok now supports post-compile transformers. Issue #217
  • FEATURE: Using @SneakyThrows no longer requires a runtime dependency on lombok.jar. In fact, any call to Lombok.sneakyThrows(ex) is optimized at the bytecode level and no longer requires you to actually have lombok.jar or lombok-runtime.jar on the classpath.
  • FEATURE: @XArgsConstructor, @Getter, and @ToString can now be used on enum declarations. Previously, behaviour of these annotations on enums was undefined.
  • FEATURE: @Getter/@Setter (and by extension, @Data) in v0.9.3 and earlier would generate getter and setter method names that did not conform to the beanspec, primarily when faced with boolean properties. This has been fixed. In practice this won't affect you unless you have properties named isFoo or hasFoo. Now the setter generated for this will be called setFoo (as the property name is foo) and not setIsFoo. Also, hasFoo is now no longer special; the names would be isHasFoo and setHasFoo. The java bean spec does not give has special meaning.
  • FEATURE: @EqualsAndHashCode (and by extension, @Data) now add a canEqual method which improves the sanity of equality amongst a hierarchy of classes. More…
  • FEATURE: @Getter now supports a lazy=true attribute. More…
  • ENHANCEMENT: The installer will now find Eclipse installations when they are located in a subdirectory of a directory containing the word 'eclipse' . Issue #283
  • ENHANCEMENT: Add null check for @Cleanup Issue #227
  • BUGFIX: Lombok is now compatible with javac 7.
  • BUGFIX: Hard to reproduce NullPointerException in Eclipse on the getTypeBinding method in the error log has been fixed. Issue #237
  • BUGFIX: @Setter and @Getter can now be applied to static fields again (was broken in v0.9.3 only). Issue #209
  • BUGFIX: delombok added type parameters to constructors that mirror the type's own type parameters. This resulted in delombok turning any generated constructor that takes at least 1 parameter of type 'T' into something that didn't compile, and to boot, a confusing error message ('T is not compatible with T'). This is now fixed. Issue #213
  • BUGFIX: The Eclipse source generator would place the generated code outside the class Issue #228
  • BUGFIX: When using m2eclipse, occasionally you'd see a ClassNotFoundError on JavacProcessingEnvironment. This has been fixed. Issue #250
  • BUGFIX: Either all or none of equals, hashCode and canEqual will be generated. Issue #313
  • BUGFIX: Delombok in output-to-directory mode was generating very long paths on mac and linux. Issue #322
  • BUGFIX: Various refactor scripts and save actions bugs have been fixed in eclipse, though most remain.

v0.9.3 "Burrowing Whale" (July 25th, 2010)

  • FEATURE: Adding @Getter or @Setter to a class is now legal and is like adding those annotations to every non-static field in it. Issue #202
  • FEATURE: Three new annotations, @NoArgsConstructor, @RequiredArgsConstructor and @AllArgsConstructor have been added. These split off @Data's ability to generate constructors, and also allow you to finetune what kind of constructor you want. In addition, by using these annotations, you can force generation of constructors even if you have your own. Issue #152
  • FEATURE: Constructors generated by lombok now include a @java.beans.ConstructorProperties annotation. This does mean these constructors no longer work in java 1.5, as this is a java 1.6 feature. The annotation can be suppressed by setting suppressConstructorProperties to true in a @RequiredArgsConstructor or @AllArgsConstructor annotation. Issue #195
  • FEATURE: generated toString, equals and hashCode methods will now use this.getX() and other.getX() instead of this.x and other.x if a suitable getter is available. This behaviour is useful for proxied classes, such as the POJOs that hibernate makes. Usage of the getters can be suppressed with @ToString/@EqualsAndHashCode(doNotUseGetters = true). Issue #183
  • ENHANCEMENT: FindBugs' @CheckForNull is now copied from a field to a setter's parameter and the getter method just like @Nullable. Issue #201
  • ENHANCEMENT: plugins and @SneakyThrows: Resolving types in annotations now works better especially for classes that aren't in the core java libraries. Issue #161
  • ENHANCEMENT: If tools.jar isn't found (required when running delombok), now a useful error message is generated. The search for tools.jar now also looks in JAVA_HOME.
  • ENHANCEMENT: toString() on inner classes now lists the class name as Outer.Inner instead of just Inner. Issue #206
  • ENHANCEMENT: All field accesses generated by lombok are now qualified (like so: this.fieldName). For those who have a warning configured for unqualified field access, those should no longer occur. Issue #121
  • ENHANCEMENT: All fields and methods generated by lombok now get @SuppressWarnings("all") attached to avoid such warnings as missing javadoc, for those of you who have that warning enabled. Issue #120
  • PLATFORMS: Lombok should now run in stand-alone ecj (Eclipse Compiler for Java). This isn't just useful for the few souls actually using this compiler day to day, but various eclipse build tools such as the RCP builder run ecj internally as well. Issue #145
  • BUGFIX: Eclipse: @Data and other annotations now don't throw errors when you include fields with bounded wildcard generics, such as List<? extends Number>. Issue #157
  • BUGFIX: complex enums didn't get delomboked properly. Issue #169
  • BUGFIX: delombok now no longer forgets to remove import lombok.AccessLevel;. In netbeans, that import will no longer be flagged erroneously as being unused. Issue #173 and Issue #176
  • BUGFIX: While its discouraged, import lombok.*; is supposed to work in the vast majority of cases. In eclipse, however, it didn't. Now it does. Issue #175
  • BUGFIX: When @Getter or @Setter is applied to a multiple field declaration, such as @Getter int x, y;, the annotation now applies to all fields, not just the first. Issue #127
  • BUGFIX: delombok on most javacs would quit with a NoSuchFieldError if it contains <?> style wildcards anywhere in the source, as well as at least 1 lombok annotation. No longer. Issue #207
  • BUILD: dependencies are now fetched automatically via ivy, and most dependencies now include sources by default, which is particularly handy for those working on the lombok sources themselves.

v0.9.2 "Hailbunny" (December 15th, 2009)

  • preliminary support for lombok on NetBeans! - thanks go to Jan Lahoda from NetBeans. Issue #93
  • lombok now ships with the delombok tool, which copies an entire directory filled with sources to a new directory, desugaring any java files to what it would look like without lombok's transformations. Compiling the sources in this new directory without lombok support should result in the same class files as compiling the original with lombok support. Great to double check on what lombok is doing, and for chaining the delombok-ed sources to source-based java tools such as Google Web Toolkit or javadoc. lombok.jar itself also provides an ant task for delombok. Full documentation of delombok.
  • Lombok now works on openjdk7 (tested with JDK7m5)! For all the folks on the cutting edge, this should be very good news. Issue #134 - thanks go to Jan Lahoda from NetBeans.
  • lombok now has various command-line accessible utilities bundled with it. Run java -jar lombok.jar --help to see them. Included (aside from the already mentioned delombok):
  • Ability to create a tiny jar named lombok-runtime.jar with runtime dependencies. The lombok transformations that have a runtime dependency on this jar can be listed as well. Run java -jar lombok.jar createRuntime --help for more information.
  • Scriptable command line install and uninstall options. Run java -jar lombok.jar install --help (or uninstall, of course) for more information. Technically this support has been there in earlier versions, but the command line options are now much more lenient, not to mention more visible.
  • Lombok now works on Springsource Tool Suite. Issue #95
  • Lombok now works on JDK 1.6.0_0, for those of us who have really old JDK1.6's installed on their system. Issue #156
  • Erroneous use of lombok in Eclipse (adding it to a project as an annotation processor, which is not how lombok is to be used on Eclipse) now generates a useful warning message with helpful information, instead of a confusing error hidden in the logs. Issue #126
  • FIXED: Regression bug where you would occasionally see errors with the gist 'loader constraint violation: when resolving...', such as when opening the help system, starting the diff editor, or, rarely, opening any java source file. Issue #141
  • FIXED: @SneakyThrows without any parameters should default to Throwable.class but it didn't do anything in javac. Issue #146
  • FIXED: Capitalization is now ignored when scanning for existing methods, so if setURL already exists, then a @Data annotation on a class with a field named url will no longer also generate setUrl. Issue #148

v0.9.1 (November 9th, 2009)

  • The installer now works much better on linux, in that it auto-finds eclipse in most locations linux users tend to put their eclipse installs, and it can now handle apt-get installed eclipses, which previously didn't work well at all. There's also a hidden feature where the installer can work as a command-line only tool (java -jar lombok.jar install eclipse path/to/eclipse) which also supports uninstall of course. You can now also point at eclipse.ini in case you have a really odd eclipse install, which should always work.
  • For lombok developers, the eclipse launch target now works out-of-the-box on snow leopard. Issue #139

v0.9.0 (November 2nd, 2009)

  • The lombok class patching system has been completely revamped; the core business of patching class files has been offloaded in an independent project called 'lombok.patcher', which is now used to patch lombok into eclipse.
  • Many behind-the-scenes changes to improve lombok's stability and flexibility on eclipse.
  • Changes to the lombok core API which aren't backwards compatible with lombok series v0.8 but which were necessary to make writing third party processors for lombok a lot easier.
  • Minor version number bumped due to the above 3 issues.
  • Eclipse's "rename" refactor script, invoked by pressing CMD/CTRL+SHIFT+R, now works on @Data annotated classes.
  • The windows installer would fail on boot if you have unformatted drives. Issue #138
  • The static constructor that @Data can make was being generated as package private when compiling with javac. Issue #136

v0.8.5 (September 3rd, 2009)

  • There's now an AccessLevel.NONE that you can use for your @Getter and @Setter annotations to suppress generating setters and getters when you're using the @Data annotation. Address Issue #110
  • Both @EqualsAndHashCode and @ToString now support explicitly specifying the fields to use, via the new 'of' parameter. Fields that begin with a '$' are now also excluded by default from equals, hashCode, and toString generation, unless of course you explicitly mention them in the 'of' parameter. Addresses Issue #105
  • There's a commonly used @NotNull annotation, from javax.validation (and in earlier versions of hibernate, which is the origin of javax.validation) which does not quite mean what we want it to mean: It is not legal on parameters, and it is checked at runtime after an explicit request for validation. As a workaround, we've removed checking for any annotation named NotNull from the nonnull support of lombok's generated Getters, Setters, and constructors. Issue #116
  • Fixed yet another issue with @SneakyThrows. This was reported fixed in v0.8.4. but it still didn't work quite as it should. Still falls under the bailiwick of Issue #103

v0.8.4 (September 2nd, 2009)

  • Fixed many issues with @SneakyThrows - in previous versions, using it would sometimes confuse the syntax colouring, and various constructs in the annotated method would cause outright eclipse errors, such as beginning the method with a try block. This also fixes Issue #103
  • Fixed the David Lynch bug - in eclipse, classes with lombok features used in them would sometimes appear invisible from other source files. It's described in more detail on Issue #114. If you suffered from it, you'll know what this is about.
  • Fixed the problem where eclipse's help system did not start up on lombokized eclipses. Issue #99
  • All generated methods now make their parameters (if they have any) final. This should help avoid problems with the 'make all parameters final' save action in eclipse. Issue #113
  • Okay, this time really added support for @NonNull and @NotNull annotations. It was reported for v0.8.3 but it wasn't actually in that release. @Nullable annotations are now also copied over to the getter's return type and the setter and constructor's parameters (but, obviously, no check is added). Any @NonNull annotated non-final fields that are not initialized are now also added to the generated constructor by @Data in order to ensure via an explicit null check that they contain a legal value.
  • @ToString (and hence, @Data) now default to includeFieldNames=true. Issue #108

v0.8.3 (August 21st, 2009)

  • @EqualsAndHashCode (and, indirectly, @Data) generate a warning when overriding a class other than java.lang.Object but not setting EqualsAndHashCode's callSuper to true. There are, however, legitimate reasons to do this, so this warning is now no longer generated if you explicitly set callSuper to false. The warning text now also refers to this action if not calling super is intentional.
  • If your fields have @NonNull or @NotNull annotations, then generated setters are generated with a null check, and the annotation is copied to the setter's parameter, and the getter's method.
  • An annoying bug that usually showed up if you had package-info.java files has been fixed. It would cause a NullPointerException at lombok.javac.apt.Processor.toUnit(Processor.java:143)

v0.8.2 (July 29th, 2009)

  • @EqualsAndHashCode and @ToString created; these are subsets of what @Data does (namely: generate toString(), and generate equals() and hashCode() implementations). @Data will still generate these methods, but you can now generate them separately if you wish. As part of this split off, you can now specify for toString generation to include the field names in the produced toString method, and for all 3 methods: You can choose to involve the implementation of the superclass, and you can choose to exclude certain fields. Issue #81
  • when compiling with javac: warnings on specific entries of an annotation parameter (such as non-existent fields in a @EqualsAndHashCode exclude parameter) now show up on the problematic parameter and not on the entire annotation. Issue #84

v0.8.1 (July 26th, 2009)

  • Changelog tracking from this version on.
  • Using eclipse's 'find callers' on a @Data annotation will now find callers of the static constructor if you generated it. If not, it still finds callers to hashCode() as before (it's not possible to make eclipse find callers to the normal constructor, though you can just use 'find callers' on the class name, which works fine). Issue #78
  • If your field is called 'hasFoo' and its a boolean, and you use @Getter or @Data to generate a getter for it, that getter will now be called 'hasFoo' and not 'isHasFoo' as before. This rule holds for any field prefixed with 'has', 'is', or 'get', AND the character following the prefix is not lowercase (so that 'hashCodeGenerated' is not erroneously identified as already having a prefix!). Similar logic has been added to not generate a getter at all for a field named 'foo' or 'hasFoo' if there is already a method named 'isFoo'. Issue #77
  • Starting the lombok installer on mac os X using soylatte instead of apple's JVM now correctly detects being on a mac, and using mac-specific code for finding and installing eclipses. Issue #80
  • For non-mac, non-windows installations, the jar file in the -javaagent parameter is now written as an absolute path in eclipse.ini instead of a relative one. For some reason, on at least 1 linux installation, an absolute path is required to make javaagent work. This 'fix' has the unfortunate side-effect of making it impossible to move your eclipse installation around without breaking the pointer to the lombok java agent, so this change has only been introduced for non-windows, non-mac. Thanks to WouterS for spotting this one and helping us out with some research on fixing it. Issue #79

v0.8

  • Initial release before announcements
