title: Eclipse plugin dependency on SWT classes not being resolved
body: <p>I have an eclipse plugin project which uses some swt objects, eg -</p>
  
  <pre><code>import org.eclipse.swt.widgets.Composite;
  </code></pre>
  
  <p>When I try to compile it with the 'Target Platform' set to 'Running Platform (Active)', it compiles fine and I dont need to import any swt specific plugins.</p>
  
  <p>However, I created a target platform with Eclipse 3.6.0 and if I set it as the active platform the project has compile errors wherever swt classes are used and cannot resolve them.</p>
  
  <p>Which plugin should I add a dependency to, to resolve these errors?</p>
  
  <p>I tried adding 'org.eclipse.swt' but that does not seem to help.</p>
