Gradle BuildConfig.class build error

Question

Hi all,

I am using few SDK's, but this is more general question. When i try to build using new Gradle system then i get this:

[ERROR] [org.gradle.BuildExceptionReporter] > com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.dex.DexException: Multiple dex files define Lcom/twitter/sdk/android/core/BuildConfig;

I know, it's classic BuildConfig.class duplicate file error:)

things that do work:

Manualy repack all jar/aar from exported project without not needed classes/files (i did not try it, but i believe)
use DEPRECATED packageBuildConfig = false

I need different, cleaner, correct way to exclude classes or other files from compile/build.

I have already spend two days reading gradle manuals, tuts, posts, examples... google... but nothing works. You can see it in commented code.

I am new to Gradle (14 days) so maybe i am missing some obvious things. I think it should be done like this:

tell gradle somehow that i dont want some classes to unpack from jar/aar to buildfolder example: \twitter-core\build\intermediates\classes\release\com\twitter\sdk\android\core\BuildConfig.class or
if there is no way to exclude files from unpacking from jar/aar to buildfolder then there must be a way to exclude some classes from compiled build while compiling. or
if there is no way to exclude files from compiling then there must be a way to delete not needed files/classes from buildfolder before compiling.

i have tried every examples i can find but they do not work for me:( not needed files are unpacked, not deleted and compiled.

Can you please help me?

@Kodl Try disable tasks generateDebugBuildConfig and generateReleaseBuildConfig by placing this code at the end of mainTemplate.gradle for all your problem projects:

 ['crashlytics', 'crashlytics-wrapper', 'fabric', 'fabric-init', 'twitter-core'].each { name ->
 project(":$name").tasks.whenTaskAdded { task ->
     if (task.name == 'generateDebugBuildConfig' || task.name == 'generateReleaseBuildConfig' ) {
         task.enabled = false
     }
 }

}

Thanks for your answer. It seems that in new versions of Unity 2017.1 and updated SD$$anonymous$$s problem is gone. Previously i have resolved it like this for every troubled modules: afterEvaluate { project -> project.tasks.transformClassesAndResourcesWithSyncLibJarsForRelease { doFirst { file("$buildDir/intermediates/classes/release/com/twitter/sdk/android/unity/BuildConfig.class").delete() } } }

But now i have much more interesting problem. I will post question soon:)
