2 files found with path 'META-INF/LGPL2.11'

Question

Does anybody knows how to debug this? I cannot figure out which libraries are generating the problem.

Side note, it only happens when I try to run Android tests so my best guess is it's related to some testing library.

    testImplementation "androidx.room:room-testing:$version_room"
    testImplementation 'junit:junit:4.13.2'
    androidTestImplementation 'androidx.test.ext:junit:1.1.3'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'
    androidTestImplementation 'androidx.test.espresso:espresso-contrib:3.4.0'
    // Compose Tests
    androidTestImplementation "androidx.compose.ui:ui-test-junit4:$version_compose"
    debugImplementation "androidx.compose.ui:ui-test-manifest:$version_compose"
    // Hilt test
    androidTestImplementation "com.google.dagger:hilt-android-testing:$version_hilt"
    kaptAndroidTest "com.google.dagger:hilt-android-compiler:$version_hilt"
    debugImplementation 'androidx.fragment:fragment-testing:1.3.6'

Answer 1

This happened for me when I added androidTestImplementation "androidx.compose.ui:ui-test-junit4:$version_compose".

Referring to the advice in this posting, I decided to use pickFirst as opposed to exclude.

According to the PackagingOptions documentation, pickFirst will allow for the first occurrence of the file to be packaged with the APK, whereas exclude would exclude all occurrences of the file.

This ended up working for me:

android {
    packagingOptions {
        pickFirst 'META-INF/AL2.0'
        pickFirst 'META-INF/LGPL2.1'
    }
}

Answer 2

So the exclude and pickFirst already deprecated in kotlin DSL. put the following in your build.gradle.kts:

android {   
    packagingOptions {
        resources.excludes.apply {
            add("META-INF/LICENSE")
            add("META-INF/*.properties")
            add("META-INF/AL2.0")
            add("META-INF/LGPL2.1")
        }
    }
}

Answer 3

This worked out for a similar issue for me:

android {
    packagingOptions {
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/*.properties'
        exclude 'META-INF/AL2.0'
        exclude 'META-INF/LGPL2.1'
    }
}
