title: Could not get unknown property 'assembleRelease' for project
body: <p>After updating Android Studio to version 2.2 and the gradle plugin to 2.2.0, I get following error:</p>
  
  <blockquote>
    <p>Error:(32, 1) A problem occurred evaluating project ':jobdispatcher'.
    Could not get unknown property 'assembleRelease' for project ':jobdispatcher' of type org.gradle.api.Project.</p>
  </blockquote>
  
  <p>The problem is in the <a href="https://github.com/firebase/firebase-jobdispatcher-android/blob/master/jobdispatcher/build.gradle" rel="noreferrer">build.gradle</a> file of an imported jobdispatcher module:</p>
  
  <pre><code>task aar(dependsOn: assembleRelease)
  </code></pre>
  
  <p>What changes can I make to fix this?</p>
  
  <p>Note, this issue is very similar to, but still a bit different to, that reported <a href="https://stackoverflow.com/q/39590549/4070848">here</a>. </p>
