title: Eclipse doesn't load plugins in the dropins folder
body: <p>I just downloaded Eclipse SDK 3.5.1 and want to install some add ons such as GEF, EMF, etc.</p>
  
  <p>I downloaded all the zip files for everything I needed and decided to install them in the dropins folder.  I read <a href="http://wiki.eclipse.org/Equinox_p2_Getting_Started" rel="noreferrer">http://wiki.eclipse.org/Equinox_p2_Getting_Started</a> and structured my dropin folder as specified:</p>
  
  <pre><code>eclipse/  
     dropins/  
       emf/  
         eclipse/  
           features/  
           plugins/  
       gef/  
         eclipse/  
           features/  
           plugins/  
       ... etc ...
  </code></pre>
  
  <p>When I start up Eclipse it does not recognize any of the features or plugins I have put into the structure above.  Any ideas?</p>
