The problem is during the build of the apk for the release, when the build for the debug happens - everything is ok, what should I do?

Question

Android

Hello, while building an apk for release (Generate Signed APK...), an error occurs
:app:transformClassesWithJarMergingForRelease FAILED
Error:Execution failed for task ':app:transformClassesWithJarMergingForRelease'.
> com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry:
(I also want to note that during the debug build everything is OK and no errors occur)
Here is the action log:

Here is my build,gradle(Module:app)

apply plugin: 'com.android.application'

        multiDexEnabled true
    }
    buildTypes {
        release {
            minifyEnabled false

}
configurations {
    all*.exclude group: 'com.android.support', module: 'support-v4'
}

build.gradle(project)

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.2'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

Well, what kind of files do I have in the project

? Guys, help, I looked around everything I could, I didn’t find anything useful in Google.

Answer 1

1. Try temporarily removing the com/unity3d/ads/android/BuildConfig.class file so that it is not visible to the compiler during compilation.
Perhaps this is the problem.
2. Clean the project before release.
