Duplicate Entry Errors with Android and MultiDex about protobuf-gradle-plugin HOT 5 CLOSED

To get this bug to show up, simply add the following line to the android config block in the testProjectAndroid

multiDexEnabled true

That will make the testProjectAndroid fail with the following error:

Error:Execution failed for task ':testProjectAndroid:packageAllArmFreeappDebugClassesForMultiDex'.
> java.util.zip.ZipException: duplicate entry: com/squareup/okhttp/OkHttpTlsUpgrader$DummyAuthenticator.class

from protobuf-gradle-plugin.

This is interesting, but it doesn't look related to the protobuf plugin.
I tried to reproduce it with the way you provided, but it builds fine.
Can you try not loading the protobuf plugin and copy the generated files (under build/generated/source/proto/) into your source directory temporarily just to see if you still have the problem?

@zhangkun83 Yeah taking generated proto files and putting them into the src/ directory and then commenting out all the plugin code in the build.gradle allowed a successful build. Thoughts?

@zhangkun83 I was mistaken. Build Project (F9) succeds. But if you attempt to run the Android build configuration I'm getting the following error:

Error:Execution failed for task ':testProjectAndroid:packageAllArmFreeappDebugClassesForMultiDex'.
> java.util.zip.ZipException: duplicate entry: com/squareup/okhttp/OkHttpTlsUpgrader$DummyAuthenticator.class

from protobuf-gradle-plugin.

FYI, following the changes made in this commit: 47d1430 I was able to resolve the issues. Not sure exactly what the root cause was (I'd love to know) but I just wanted to let you know that this fixed the issue.
