title: Running Proguard on Android app with libs written in Scala
body: <p>I have an android project that will be written in Java but will utilize some libs written in Scala. </p>
  
  <p>I'm using the AndroidProguardScala plugin to build be a minimal Scala lib, but it doesn't seem to pick up the fact that the JARs in my project also need some of the Scala API included, causing the app to fail when these methods are called. </p>
  
  <p>What am I missing?</p>
