title: Remove Gradle Warnings: Could not find google-services.json
body: <p>Switched from <strong><code>google-services:3.1.1 to 3.2.0</code></strong> since then I get the following warning</p>
  
  <pre><code>Could not find google-services.json while looking in [src/nullnull/debug, src/debug/nullnull, src/nullnull, src/debug, src/nullnullDebug]
  
  Could not find google-services.json while looking in [src/nullnull/release, src/release/nullnull, src/nullnull, src/release, src/nullnullRelease]
  </code></pre>
  
  <p>I see in my gradle console that the <code>JSON</code> file is parsed from the right place, as it is expected if you didn't use any flavors.</p>
  
  <pre><code>Parsing json file: C:\testApp\app\google-services.json
  </code></pre>
  
  <p>So building works fine. </p>
  
  <p>But I really like a clean console output, so how can I remove this warning that seems not needed?</p>
