title: Gradle - build sass per productflavor (multi folder)
body: <p>We created an Android app with a webview which shows a local website from the assets folder.</p>
  
  <p>The project has different Product Flavors to generate diffent apps with different styles and content but with the same codebas (native Java and HTML / JS).</p>
  
  <p>For each flavor we want to define a diffent sass file with the colors and tweaks for that specific flavour.</p>
  
  <p>I know that I need to create a task in gradle which builds the CSS files but I have no idea where to start:</p>
  
  <ul>
  <li>How do I get the url of the assets folder of a specific flavour?</li>
  <li>Can I use a special gradle plugin for building sass or do I have to create a task which executes the "sass" command?</li>
  <li>When I use another gradle plugin like compass, how do I configure the right folders for each flavour? The plugin settings are in the top level and not in the Android plugin level.</li>
  </ul>
