title: Google Cloud Speech API protobuf is causing 'debugAndroidTestCompile' not found
body: <p>I have copied and compiled the source code for speech api last month on this location <a href="https://github.com/GoogleCloudPlatform/android-docs-samples/tree/master/speech/Speech" rel="nofollow noreferrer">https://github.com/GoogleCloudPlatform/android-docs-samples/tree/master/speech/Speech</a> 
  and works. Now, when I revisited it, I'm having a <strong><em>Configuration with name 'debugAndroidTestCompile' not found.</em></strong> error.</p>
  
  <p>What is causing this? If you ask me how did I know it is the one, I did the process of elimination. I removed one by one on the gradle file and sync. When I removed <strong><em>apply plugin: 'com.google.protobuf'</em></strong> the error disappears.</p>
