Support SMAP generated by Kotlin 1.5 compiler (Support JSR-45 spec)

[max-kammerer]

Prior version 1.5 Kotlin compiler violate JSR-45 specification in case of several stratum presence that was fixed in 1.5. There was a problem with *E presence between stratums which according to specification should be presented only at the end of SMAP (more details could be found in https://youtrack.jetbrains.com/issue/KT-37704).

Now proper SMAP output breaks JaCoCo parser with Unexpected SMAP line: *S KotlinDebug exception.
Repro project could be found in https://youtrack.jetbrains.com/issue/KT-44757

Reduced reproducer:

for Example.kt

inline fun f() {}
fun g() = f()

execution of

./kotlin-1.4.30/bin/kotlinc -language-version 1.5 Example.kt

java -jar ./jacoco-0.8.6/lib/jacococli.jar classinfo ExampleKt.class

fails with

Exception in thread "main" java.io.IOException: Error while analyzing ExampleKt.class.
Caused by: java.lang.IllegalStateException: Unexpected SMAP line: *S KotlinDebug

When will this be fixed for Gradle and Kotlin 1.5?

[overfullstack]

This issue still exists. When can we expect a fix?

[marchof]

Just check the FAQ:

When will feature X be released?

JaCoCo is maintained by volunteers in their free time. Since we cannot guarantee free capacity, we do not commit to particular release dates. Typically, you can expect a couple of releases every year.

In the change log, you can see all features that have been implemented in master branch and will be available with the next release. And in the meantime you can test latest build of master branch (Maven SNAPSHOT) and provide feedback to us.

It is fixed in the next version, so you have to wait until 0.8.7 is released. In urgent cases you can start using the 0.8.7-SNAPSHOT available via Snapshot Builds

you can't have such stack trace when you really use JaCoCo 0.8.7, because in 0.8.7 throw is not located on line 98, but on line 102:

https://github.com/jacoco/jacoco/blob/v0.8.7/org.jacoco.core/src/org/jacoco/core/internal/analysis/filter/KotlinInlineFilter.java#L102

[laalto]

Yeah, that's interesting. Using the jacoco gradle plugin with classpath "org.jacoco:org.jacoco.core:0.8.7" in project-level build.gradle. Digging deeper

[Godin]

Using the jacoco gradle plugin with classpath "org.jacoco:org.jacoco.core:0.8.7"

Regarding https://docs.gradle.org/current/userguide/jacoco_plugin.html
please see #1164 (comment) that states the same as in mentioned above Gradle documentation:
jacoco.toolVersion can be set to non-default value to use specific version including 0.8.7

For the other Gradle plugins, please refer to their documentation.

Thanks for the quick responses. Looks like the project had some legacy to be updated in its jacoco setup. jacoco.toolVersion didn't work though, needed to use a construct like in https://stackoverflow.com/questions/63479850/jacoco-gradle-plugin-ignoring-version to force 0.8.7 to be used and to get migration to kotlin 1.5.0 proceed further.

@laalto Even that is not working for me.. still seeing error on line 98 means it's not using 0.8.7. Any ideas why or what else can I try?

This worked in my case:
If you have a multi-module project, you can specify jacoco toolVersion in allProjects

allprojects {
    jacoco {
        toolVersion = "0.8.7"
    }
    //..
}

[Maksym-Motornyi]

To force use 0.8.7 version just add this to the project level gradle file:

subprojects {
    configurations.all {
        resolutionStrategy {
            eachDependency { details ->
                if ('org.jacoco' == details.requested.group) {
                    details.useVersion "0.8.7"
                }
            }
        }
    }
}

@Maksym-Motornyi Still got the error on line 98

java.lang.IllegalStateException: Unexpected SMAP line: *S KotlinDebug
	at org.jacoco.core.internal.analysis.filter.KotlinInlineFilter.getFirstGeneratedLineNumber(KotlinInlineFilter.java:98)

which by @Godin comment (#1155 (comment) ) means the project is still not using 0.8.7 version.

In my case is working fine when I run tests local with Android studio, but got the issue on a remote Jenkins machine.

[NikolayMetchev]

Have you updated the Jenkins Jacoco plugin https://plugins.jenkins.io/jacoco/?

Have you updated the Jenkins Jacoco plugin https://plugins.jenkins.io/jacoco/?

thank you! updating to 3.2.0 has fixed it.
