Android Studio: Exclude resource file under resources sourceSets
Solution 1:
Exclude paths aren't currently supported for Android sourceSets. You can track this at bug https://code.google.com/p/android/issues/detail?id=64957
This is happening because Android sourceSets aren't the same as Java sourceSets; they're a custom implementation in the Android plugin, and don't automatically pick up all the features of their cousins. This will need to be specially implemented for Android, and it hasn't been done yet.
