Unable to generate signed APK - duplicate entry: javax/annotation/CheckForNull.class

Question

 Error:Execution failed for task ':app:transformClassesWithJarMergingForRelease'. > com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: javax/annotation/CheckForNull.class

Below is my app level gradle file. I tried removing appcompat, support v4, but it was no help. The app is working fine otherwise, I'm getting the error only when I'm trying to generate a signed apk.

Also, there are two CheckForNull class, infact there are duplicate classes in jsr-305. The screenshot:

What would be a wise solution to this problem?

It seems to me, that you there are at least two libraries in your `build.gradle`, which both have `javax` as their dependency (aka transitive dependency). So, you are importing two different versions of `javax` lib into your codebase, and that's why you have doublicated classes. Just look thtough all the dependencies `./gradlew app:dependencies` and find two libs that have dependency of `javax` and exclude that dependency for one of them. — azizbekian, Feb 15 '17 at 14:43

It's OK that jsr305 contains CheckForNull *et al.* twice: one entry is the source (java), the other is compiled (class). — Alex Cohn, Mar 14 '18 at 11:34

Please do clean for gradle build using command ./gradlew clean.
