title: My maven Java project in Eclipse doesn't generate jar file
body: <p>If I use command line command like "mvn compile" and "mvn install", I see a jar file under target directory.</p>
  
  <p>But if I build the same project from Eclipse using m2e plugin, I don't see a jar file but only compiled class directories under target directory but they are empty. Any insight on this problem? </p>
