title: android studio "Use gradle wrapper" grayed out
body: <p>I try to import an eclipse project into Android studio.
  In the <a href="http://developer.android.com/sdk/installing/migrate.html">migration instructions</a> it says "In the following dialog, leave Use gradle wrapper selected and click OK. (You do not need to specify the Gradle home.)"</p>
  
  <p>The problem is that the ""Use gradle wrapper" is unselected and grayed out. </p>
  
  <p>Any suggestions?</p>
