title: Gradle error on Android Studio startup
body: <p>Every time I start Android Studio I get the following error:</p>
  
  <blockquote>
    <p>Gradle 'VertretungsplanProject' project refresh failed: Could not
    fetch model of type 'IdeaProject' using Gradle distribution

  <p>My project looks like this:</p>

  <p>When I want to compile now this error appears:</p>
  
  <blockquote>
    <p><strong>Deprecated make implementation</strong><br>
    Old implementation of "Make" feature is enabled for this project.
    It has been deprecated and will be removed soon.
    Please enable newer 'external build' feature in Settings | Compiler.</p>
  </blockquote>
  
  <p>After changing this setting to <code>Use external build</code> everything is working fine.
  But this appears every time I start Android Studio and this is really annoying. </p>
  
  <h1>UPDATE</h1>
  
  <p>I deleted the <code>android-support-v4.jar</code> from the <code>libs</code> folder and simply wrote <code>compile 'com.android.support:support-v4:18.0.0'</code> to the <code>build.gradle</code> of ActionbarSherlock. Then the <code>android-support-v4.jar</code> is used from the installed SDK.</p>
