Exclude .jar from compilation in Android Studio using Gradle

Question

I currently have something similar in the build.gradle file.

dependencies { compile 'com.android.support:support-v4:13.0.+' compile ('com.xxx:xxx-commons:1.+') { } } 

There is a problem because jUnit and hamcrest-core are present in the com.xxx:xxx maven repository, creating this error:

 Gradle: Origin 1: /Users/yyy/.gradle/caches/artifacts-26/filestore/junit/junit/4.11/jar/4e031bb61df09069aeb2bffb4019e7a5034a4ee0/junit-4.11.jar Gradle: Origin 2: /Users/yyy/.gradle/caches/artifacts-26/filestore/org.hamcrest/hamcrest-core/1.3/jar/42a25dc3219429f0e5d060061f71acb49bf010a0/hamcrest-core-1.3.jar Gradle: Execution failed for task ':android:packageDebug'. > Duplicate files copied in APK LICENSE.txt File 1: /Users/yyy/.gradle/caches/artifacts-26/filestore/junit/junit/4.11/jar/4e031bb61df09069aeb2bffb4019e7a5034a4ee0/junit-4.11.jar File 2: /Users/yyy/.gradle/caches/artifacts-26/filestore/junit/junit/4.11/jar/4e031bb61df09069aeb2bffb4019e7a5034a4ee0/junit-4.11.jar 

Since jUnit actually includes the hamcrest library these days, there is a way to actually exclude the jar, which is: hamcrest-core-1.3.jar Or exclude all .txt files or exclude jUnit together from the maven repository (it is not used).

Any other ideas that might be helpful?

Yes, you can exclude transitive dependencies :

In your case, it will be:

 dependencies { compile 'com.android.support:support-v4:13.0.+' compile ("com.xxx:xxx-commons:1.+") { exclude group: 'junit', module: 'junit' } } 

or

 configurations { all*.exclude group: 'junit', module: 'junit' }
