title: Add external jars to Eclipse plugin classpath
body: <p>In the manifest file for an eclipse plugin its possible to add jar files and
  folders to the classpath (on the <em>Runtime</em> tab).</p>
  
  <p>In the root of my plugin I have a folder <code>lib</code> containing <code>a-1.0.1.jar</code>, <code>b-1.0.0-SNAPSHOT.jar</code>. But only when I select each jar separately:</p>
  
  <pre><code>Bundle-ClassPath: .,
   lib/a-1.0.1.jar,
   lib/b-1.0.0-SNAPSHOT.jar
  </code></pre>
  
  <p>...can they be used inside my project. Why is it not possible to add them to the classpath by adding the common root folder only:</p>
  
  <pre><code>Bundle-ClassPath: .,
   lib/
  </code></pre>
  
  <p>?</p>
