title: Obfuscation across multiple gradle modules with proguard possible?
body: <p>I have a Gradle project containing the main module and one library module and each one is set up with proguard.</p>
  
  <p>My problem is, that the class which is obfuscated in the library module to "A" or similar is still referenced from the main module with the original name, lets say "MyUtil", which doesn´t exist anymore.</p>
  
  <p>I don´t want to exclude this class from the obfuscation if possible, so is there any way to do obfuscation accross modules?</p>
