title: How can I create a self-consistent .jar file with Eclipse?
body: <p>I wrote my Java application in Eclipse. Now I would like to generate a .jar file which can be run on other systems from the command line. Is there a easy way to do it in Eclipse?</p>
  
  <p>In particular I am wondering what should I do with the jar files of external library that I use (should it be included into my .jar file?).</p>
  
  <p>Moreover, should I generate some manifest files?</p>
  
  <p><strong>ADDED:</strong></p>
  
  <p>I see the window in which I can choose "Extract required libraries into generated JAR" or "Package required libraries into generated JAR" and so on. I select the first option, I specify export destination but "Next" button is not activated yet. What else should I specify. I am offered to launch a configuration but i do not want to. Every configuration is associated with a fixed set of parameters given in the command line and I do not want that.</p>
