title: accidentally deleted the default output folder in eclipse
body: <p>I was rearranging some files in eclipse, and I accidentally deleted the default output folder.  This is the location where eclipse stores the class files.  Can anyone show how to recover it?  Or rebuild it from the .java files?  </p>
  
  <p>EDIT:  </p>
  
  <p>I just restored the project from backup files.  So this question is no longer relevant.  Unless some future reader did not backup their application before making this same mistake.</p>
