I had the same problem and the testlib depended on lib.
So what I did is:
- use gradle-android-test-plugin (I currently use the deprecated one from
Jake, but any should do)
- in lib, create a new task to create a jar of the files that will be
needed by the app
> task packageTests(type: Jar, dependsOn: 'compileDebugTestJava') {
> from files('src/test/java')
> }
>
- now in the app, I reference the lib code for tests:
> testCompile fileTree(dir: '../libraries/common/common-lib/build/libs',
> include: 'common-lib.jar')
>
- and I add a dependency so the new lib task will be called automatically:

Perhaps there are more elegant ways to make it work, but it works for me :)
