title: RoomProcessor compilation or a circular dependency
body: <p>I've been struggling for days with and issue with Android Room component. </p>
  
  <p>All I did was upgrade my Android studio from 3.3 to 3.4.1, this comes with changes to gradle etc that are done. 
  I've even tried going back to 3.3, but nothing is working. 
  I've have run with <code>Run with --info or --debug option</code> to try see more details but nothing gives me more info. Please help</p>
