title: Eclipse could not export android project to gradle based
body: <p>I followed <a href="https://developer.android.com/sdk/installing/migrate.html" rel="nofollow noreferrer">official documentation</a> tips and could no pass the problem that it displays windows with Exported modules, and even I tick "Force overiding of exsting files", nor finish does not bring any effect. Even we tick all submodules for main project it still blocked.</p>
  
  <p>Any ideas what might cause that problem?</p>
