title: Package does not exist when using separate App as a dependency
body: <p>I'm trying to compile an App utilising a separate App as a dependency but when I compile referencing modules from this library I see several "error:package does not exist" and "error:cannot find symbol class" messages from graddle. The following are my two build files. </p>

  <p>Can anyone help/experienced this before? Android Studio does not highlight any issues in the class and I can ctrl+click through to the packages referenced which seems to mean it is set up correctly...</p>
  
  <p>Thanks!</p>
