body: <p>When trying to install the ADT plugin following Android Developper Site' <a href="http://developer.android.com/sdk/eclipse-adt.html" rel="nofollow">instructions</a> on a freshly installed Eclipse, I obtained the following error message:</p>
  
  <pre><code>An error occurred while collecting items to be installed
