title: Eclipse Plugin project with other project dependencies
body: <p>I have an Eclipse plugin project, and it depends on other projects that I have in my Eclipse workspace. After adding the project dependencies under "Java Build Path" -> "Projects" tab, and also selecting the project in the "Order and Export" I get a java.lang.NoClassDefFoundError.</p>
  
  <p>I'm assuming that the other projects have not been properly included into the plugin. Does anyone know how to fix this?</p>
  
  <p>Thanks,
  James</p>
