title: Manage aar dependencies in my aar
body: <p>We ship an aar to our customer(say A). Now our code uses a 3rd party AAR (say B). Now when we use this 3rd party AAR we add a compile dependency in our AAR's gradle. </p>
  
  <pre><code>compile 'B@aar'
  </code></pre>
  
  <p>The problem is that our customer wont have B.aar in their repo and we cant explicitly provide them a 3rd party AAR. How can I bundle B as a dependency in my aar?</p>
