I hate tooling around Scala with libGDX so much - Gradle, Gradle Android plugin and ProGuard are just awful.

For example today I got during compilation: "Warning: Exception while processing task java.io.IOException: Please correct the above warnings first."

Grepping build log for (case insensitive) "warn" returns only the message above to correct warnings.

What the hell? I am required to correct not existing or invisible warnings or what? I hate you Gradle and ProGuard, I really do! >:(
