title: Eclipse 3.8.1 - hiding external jars from the project view
body: <p>The title more or less says it, I think.</p>
  
  <p>In earlier versions of Eclipse - windows or linux - when I've imported external jars, these haven't been visible in the project view, along with the packages, sources and other resources. </p>
  
  <p>Now, in Eclipse 3.8.1, in Ubuntu 14.04 LTS, this has changed. When I import some 50 external jars in my project, all of these are listed in the project view, cluttering the windows unnecessarily.</p>
  
  <p>I've been looking in the settings and preferences, but I cannot see a way to hide them. Anyone know how?</p>
