title: Include external module in Android Library aar
body: <p>I have a simple enough Android Library <code>build.gradle</code> file (irrelevant parts removed),</p>
  
  <pre><code>apply plugin: 'com.android.library'
  
  repositories {
      maven { url 'https://dl.bintray.com/alexeydanilov/maven' }
  }
  
  dependencies {
      compile 'com.danikula:videocache:1.0.1'
  }
  </code></pre>
  
  <p>And I would like to be able to build an Android Library <code>.aar</code> which has all the files I want in it, but also all the files which come down from the <code>videocache</code> external module.</p>
  
  <p>I've tried many different techniques to try and achieve this (another project, changing settings of 'transitive', attempting 'export = true') but all have proven unsuccessful and I'm not sure what else I can try.</p>
  
  <p>If I download the source .jar file drop it in to libs, add the necessary bits to the settings file, it packages into the <code>.aar</code> correctly, but I can't seem to find any way to do it via referencing the external module like this.</p>
