More than one file was found with OS independent path 'META-INF/library_release.kotlin_module'

Hi, when I add the library to the app/build.gradle file:

debugImplementation "com.github.ChuckerTeam.Chucker:library:3.0.1"
releaseImplementation "com.github.ChuckerTeam.Chucker:library-no-op:3.0.1"

I get the following build error:

Execution failed for task ':app:mergeDebugJavaResource'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade
   > More than one file was found with OS independent path 'META-INF/library_release.kotlin_module'

Indeed, I have 2 libraries with this file, one of them is chucker:

There is a way to fix this with packagingOptions:

packagingOptions {
    exclude 'META-INF/library_release.kotlin_module'
}

However it seems that the root cause can be solved on the library, which is better because it avoids having everyone to add the exclude fix:

Takhion/android-extras-delegates#1
kosi-libs/Kodein#138

Would be nice if this was fixed at the library :)

I've found this related to the error: https://readyset.build/build-failures-kotlin-metadata-errors-f0090cdf948c

I've opened an issue on the other library too: kizitonwose/Calendar#65

Thanks for the report @AlbertVilaCalvo
