Several people have asked for this on EAP and seemed to like the IDE. I tried making a test patch to do it and it works OK, it seems harmless. The problem is that people do not always see the status
 bar in the Main Window and when compilation succeeds, only that status message is shown, which does not reassure them that it was OK. Printing a message in the Compiler window makes it clear, esp. fo
r new users, that the compilation finished. Also for very long compilations, if you e.g. open another file while the compile is running, the message Opening XXX.java... will appear and disappear, and
afterwards (if you were not watching carefully) it is not clear whether the compilation finished or is still going on.

For failed compiles, there is presumably some error message so this is not necessary.

Suggested patch: in CompilerDisplayer.java, change:

    MessageFormat msg = task.isSuccessful() ? compSuccess : compUnsuccess;
    setStatusText(msg.format (new Object[] { task.getDisplayName() }));

to:

    if (task.isSuccessful ()) {
      String msg = compSuccess.format (new Object[] { task.getDisplayName () });

      setStatusText (msg);
      println (msg);
    } else {
      setStatusText (compUnsuccess.format (new Object[] { task.getDisplayName () }));
    }
