title: Error creating Runnable jar in eclipse
body: <p>I have a project that I'd like to make a Runnable Jar from.
  I have a Run Configuration that works from within Eclipse.
  When I try to Export a Runnable Jar, I get this error for every .jar the project uses:
  "Fat Jar Export: Could not find class-path entry for "</p>
  
  <p>Any ideas on what I need to do to make this work?</p>
