title: More than one library with package name
body: <p>My Gradle dependencies includes:</p>

  <p>I am getting BUILD FAILED with error:</p>
  
  <blockquote>
    <p>Error:Execution failed for task ':app:processDebugResources.
    Error: more than one library with package name 'com.google.android.gms'
      You can temporarily disable this error with android.enforceUniquePackageName=false
    However, this is temporary and will be enforced in 1.0</p>
