title: How to add Gradle backing to existing project?
body: <p>In the process of trying to get my project running on Gradle I have installed and setup Gradle for my new project. </p>
  
  <p>My problem is that I keep getting an error <strong>"Module X is not backed by Gradle"</strong>. I've run <code>gradle setupBuild</code> and the files seem correct, but when running in Android Studio it won't stop the error.</p>
  
  <p>Here's a screenshot of what I'm getting:</p>

  <p>So I'm wondering how to add Gradle backing to the project within Android Studio if the project is already in there.</p>
