title: Gradle Build gets stuck at Executing tasks: [:app:generateDebugSources, :app:generateDebugAndroidTestSources]
body: <p>I am running Android Studio 1.3.2 on Ubuntu 14.04, with build-tools version 23.0.0. </p>
  
  <p>Whenever I load any project, after the indexing is complete, Gradle shows Gradle Build Running and no matter how long I leave it, it shows no progress or errors.</p>
  
  <p>I have tried these solutions:</p>
