title: Unity Gradle build failed when version changed after adding google plugins
body: <p>I'm a beginner developer in Unity and trying to build a game. But whenever I add a google plugin(either it is firebase, AdMob or play games services) and try to change my version number or name, grade build failed with tons of errors.</p>
  
  <p>I think something in player settings and the files which google added conflicts. How do I fix this?</p>
