Legacy UI whole app gradle 8.1.2

[sucicf1]

About this issue

• When I put the code to use in only one module it works with the following workaround:
  implementation("com.mikepenz:aboutlibraries:10.8.3") {
  exclude group: 'com.mikepenz', module: 'aboutlibraries-core'
  }
  But when I want to apply it to the whole app then it on synchronize gives an error without the above workaround or using the above workaround it gives a blank page in user interface of android app

Details

com.android.tools.build:gradle:8.1.2
id 'com.mikepenz.aboutlibraries.plugin' version "10.8.3"

[mikepenz]

Can you please provide more details? Which error do you get?

[sucicf1]

when I don't use the workaround sometimes I can sync and sometimes not the gradle files. But even if I can sync gradle files I get during building my apk the following error (similar error when I can't sync gradle files):

when I use the workaround I can sync gradle and build apk but running the app when it needs to display the package list it displays empty and in logcat I found the following:

[mikepenz]

This looks to be like 2 different reports.

For the first: It seems the jettifier is somehow duplicating classes. Do you really still need the jettifier in your app?

For the second. Please make sure the plugin is properly applied, and the generation of the meta data works. (the build folder should contain the json output, unless you have it configured to manually generate the data?)

[sucicf1]

Currently I have only one module and use the module wide solution. I can't remove jetifier without some medium work. On the other hand in the second case I see in logcat:
Unable to retrieve library information given the raw resource identifier.
Please make sure either the gradle plugin is properly set up, or the file is manually provided.
I am setting up the gradle plugin like following:

plugins {
    id 'com.mikepenz.aboutlibraries.plugin' version "10.8.3"
} 

Is that OK?

[sucicf1]

I removed the jetifier and still get the duplicate class error.

[mikepenz]

Could it be possibly similar problem like: #881 (comment)

[dhoehl]

I have the same issue on def latestAboutLibsRelease = '10.9.2.

    //implementation "com.mikepenz:aboutlibraries-core:${latestAboutLibsRelease}"
    //implementation "com.mikepenz:aboutlibraries:${latestAboutLibsRelease}"

produces:
java.lang.ClassNotFoundException: Didn't find class "com.mikepenz.aboutlibraries.util.AndroidExtensionsKt"

Using this workaround

implementation("com.mikepenz:aboutlibraries-core-android:${latestAboutLibsRelease}")
    implementation("com.mikepenz:aboutlibraries:${latestAboutLibsRelease}") {
        exclude group: 'com.mikepenz', module: 'aboutlibraries-core'
    }

works, but the list of libraries is empty.

My build.gradle

buildscript {
....
}

plugins {
    id 'com.mikepenz.aboutlibraries.plugin' version "10.9.2"
}

App level

plugins {
    id 'com.mikepenz.aboutlibraries.plugin'
}

Code to call the library:

            new LibsBuilder()
                    .withAboutIconShown(true)
                    .withAboutVersionShown(true)

                    .withListener(...)
                    .start(this);

Using library version 8.9.4 shows at least two items in the list: The AboutLibrary lib and FastAdapter (I guess used by AboutLibraries)

[mikepenz]

is the build/generated/aboutlibraries staying empty even when doing a clean build?

if you manually run the gradle task, would it have dependencies resolved?

./gradlew findLibraries

What gradle version are you using?

[dhoehl]

Using Gradle 8.4.

./gradlew findLibraries

let to

Error occurred during initialization of VM

Changing

to

solved this issue.

The library still isn't working after clean rebuild. (No build/generated/aboutlibraries folder available)

./gradlew findLibraries

When I try to build a realease build I also get this:

C:/Users/.../.gradle/caches/transforms-3/3da79f2f13a3f61c7d4287911f5a6908/transformed/aboutlibraries-10.9.2/jars/classes.jar!/META-INF/aboutlibraries.kotlin_module: Module was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.9.0, expected version is 1.7.1.

Project is written in java. Only external libraries might use kotlin. I do not have anything related to kotlin defined in my build.gradle files

[dhoehl]

Please have a look on this MWE: https://github.com/dhoehl/LibraryTest

It demonstrates the crash if this code is not used:

implementation("com.mikepenz:aboutlibraries-core-android:${latestAboutLibsRelease}")
    implementation("com.mikepenz:aboutlibraries:${latestAboutLibsRelease}") {
        exclude group: 'com.mikepenz', module: 'aboutlibraries-core'
    }

and it also demonstrates the missing json file (and resulting empty library screen. Simply change the build.gradle to reproduce both errors

    //Uncomment this and comment block (2) will let the app crash
    //Block (1)
    //implementation "com.mikepenz:aboutlibraries-core:${latestAboutLibsRelease}"
    //implementation "com.mikepenz:aboutlibraries:${latestAboutLibsRelease}"

    //Uncomment this and comment block (1) so the app will start library screen but without any library present
    //Block (2)
    implementation("com.mikepenz:aboutlibraries-core-android:${latestAboutLibsRelease}")
    implementation("com.mikepenz:aboutlibraries:${latestAboutLibsRelease}") {
        exclude group: 'com.mikepenz', module: 'aboutlibraries-core'
    }

[mikepenz]

Thank you for this. I'll try to come to this as soon as possible

[dhoehl]

I have some new insights:

Using this at top level gradle will reproduce the error (no json file in build folder)

plugins {
    id 'com.mikepenz.aboutlibraries.plugin' version "10.9.2"
}

But using this in top level gradle resp. in module gradle will produce the json file. In my MWE example this solves all issues and creates a full working library screen.

plugins {
    id 'com.mikepenz.aboutlibraries.plugin' version "10.9.2" apply false
}

plugins {
    id 'com.mikepenz.aboutlibraries.plugin'
}

In my production app this helped as well. The screen is not blank anymore and the app does not throw an exception. Nevertheless the json that is produced is empty. The build log gives me the following output for every library:

> Task :app:prepareLibraryDefinitionsDebug
--> Retrieved no components for: androidx.activity:activity:1.8.0
--> Retrieved no components for: androidx.activity:activity-ktx:1.8.0
--> Retrieved no components for: androidx.annotation:annotation-experimental:1.3.0
--> Retrieved no components for: androidx.annotation:annotation-jvm:1.6.0
--> Retrieved no components for: androidx.appcompat:appcompat:1.6.1
--> Retrieved no components for: androidx.appcompat:appcompat-resources:1.6.1
--> Retrieved no components for: androidx.arch.core:core-common:2.2.0
...

I could not figure out the difference between the MWE and my real app. But we are getting closer to a solution, I think.

I deleted .idea, .gradle and build dir still get the same result.

[dhoehl]

Add this org.gradle.unsafe.configuration-cache=false to your gradle.properties file. With the above fix and workarounds the library works again finally.

So it was the gradle configuration cache after all

[mikepenz]

Thank you for the update @dhoehl

[mikepenz]

Closing as config cache problems are tracked here: #839
