title: How to edit a gradle dependency
body: <p>I'm working on an android project that uses the following dependency in my gradle file;</p>
  
  <pre><code>compile 'com.mapzen:on-the-road:1.1.1'
  </code></pre>
  
  <p>I would like to edit one of the files in order to add some missing features and contribute to the project. </p>
