title: how do I add classpath to the exported runnable java .jar file using eclipse
body: <p>so my projects have a lot of classpath variables set in the run configuration -> classpath tab in eclipse...</p>
  
  <p>but once I exported the project as a runnable java jar file, none of these classpaths are exported to the jar's manifest file despite having specified this run configuration during the export dialogue....</p>
  
  <p>how do I get eclipse to add these classpath variables to the exported jar's manifest? </p>
  
  <p>besides doing everything manually of course...</p>
