Hello, during build 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' android { compileSdkVersion 24 buildToolsVersion "23.0.1" defaultConfig { applicationId "com.example.subwaykiev10" minSdkVersion 15 versionCode 1 versionName "1.0" targetSdkVersion 23 multiDexEnabled true } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } } dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) testCompile 'junit:junit:4.12' compile 'com.android.support:appcompat-v7:24.1.1' compile 'com.google.android.gms:play-services:9.4.0' compile 'com.google.android.gms:play-services-location:9.4.0' compile 'com.google.android.gms:play-services-ads:9.4.0' compile 'com.google.android.gms:play-services-auth:9.4.0' compile 'com.google.android.gms:play-services-gcm:9.4.0' compile project(':unity-ads-1.5.8') compile project(':cheetah-mobile-3.4.7') //compile(project(':..:..:..:..:..:..:android_libraries:walletsdkandroidmodule')) { // exclude group: 'com.google.code.gson' //} } 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 }

So what kind of files do I have in the project? image

     duplicate entry: com/unity3d/ads/android/BuildConfig.class

    This means that you have 2 unity-ads libraries connected. You have connected two jar with different versions of this library. Check and delete one of them. Most likely, one is connected through a separate project (compile project (': unity-ads-1.5.8')), and the second lies in libs.

      Most likely the connected modules use the same libraries.

      Check is not difficult, simple way:

      Go to the Project -> External Libraries tab and analyze and compare the libraries used there.

      Then in build.gradle one of the conflicting libraries is included in the exclude corresponding module

      • I will soon test your solution and unsubscribe (waiting for the project to drop ) - Bellkross
      • There are no duplicate libraries, of course, of type firebase-analytics-9.4.0 and firebase-analytics-impl-9.4.0 But are they different libraries? - Bellkross
      • there may be classes with the same signature - the package name and the class name are the same - s_klepcha
      • Or rather, what specifically to look for? - Bellkross
      • @Bellkross pointed to one of the unity-ads-1.5.8 projects, look for the com.unity3d.ads.android.BuildConfig class there and in one of the jar-ok. These are not necessarily different versions of libraries. - s_klepcha
