title: Exception while doing past iteration backup: Source
body: <p>I am working on Android project. I connected my phone to Android Studio in order to test the app. After second upload <code>Gradle Build</code> failed and gave this error:</p>
  <blockquote>
  <p>Error:Execution failed for task ':app:buildInfoDebugLoader'.</p>
  <p>Exception while doing past iteration backup : Source /home/ziyaddin/AndroidStudioProjects/Test/app/build/intermediates/builds/debug/19181584762318/classes.dex and destination /home/ziyaddin/AndroidStudioProjects/Test/app/build/intermediates/builds/debug/19181584762318/classes.dex must be different</p>
  </blockquote>
  <p>What can be the reason for that? How to solve this problem?</p>
