title: auto-generated java files in Eclipse
body: <p>How to understand which are the auto-generated files in a huge Java project developed in Eclipse?</p>
  
  <p>I am a newbie. For example, little by little, I am discovering that many files are generated by using <code>xcore</code> plug-in. Other with <code>xtend</code>. Just going through the code and trying I am learning and that's ok. The question is: is there a way to understand which files to modify to automatically regenerate the others? My error was to start modifying all the files manually.</p>
