title: Uploading ProGuard Mapping Files to Firebase
body: <p>Am trying out the recently released feature that allows uploading of ProGuard mapping file to Firebase (<a href="https://firebase.google.com/docs/crash/android" rel="noreferrer">https://firebase.google.com/docs/crash/android</a>) using gradle task.  The following is the task I'm running.  </p>
  
  <pre><code>./gradlew -PFirebaseServiceAccountFilePath=xxxxx.json :app:firebaseUploadReleaseProguardMapping
  </code></pre>
  
  <p>However, it doesn't seem to be recognizing service account file.  Has anyone had any luck getting this working?  I've also tried defining <code>FirebaseServiceAccountFilePath</code> in gradle.properties.</p>
  
  <pre><code>* What went wrong:
  Execution failed for task ':app:firebaseUploadReleaseProguardMapping'.
  &gt; Service account file path has not been defined! Service accounts are used to authorize your mapping file uploads.  Learn more at
