Application CLOSE after running org.apache.tools.ant.Main.main()
Hi ,
My Java Application (Swing) closed after executing
org.apache.tools.ant.Main.main(). Anybody have a clue to what have
happened?
I even created separate thread when running
org.apache.tools.ant.Main.main(). It did not help.
Thanks in advance !

This should be a taglib, surely, one that takes stuff inline...

Yes, I'm pretty sure thats the primary (only?) reason for the call to
System.exit.
But it seems folks should be integrating with Ant by emulating what
Main.main does rather than simply invoking it directly. I've toyed with
writing a servlet that ran Ant once upon a time. I just dug up the code
and here it is:
final Project project = new Project();
AntListener listener = new AntListener();
project.addBuildListener(listener);
File buildFile = new File(buildFile);
Throwable exception = null;
try {
project.fireBuildStarted();
project.init();
ProjectHelper.configureProject(project, buildFile);
project.executeTarget(project.getDefaultTarget());
}
catch (BuildException e) {
exception = e;
}
finally {
project.fireBuildFinished(exception);
Writer out = response.getWriter();
out.write(listener.getLog());
}
AntListener is just a BuildListener implementing class that collects all
the log messages for grabbing later (in the finally clause). This is
just a simple example, and one that probably needs lots of improvement
to be solid, but its better than calling Main.main, IMO.

I got bitten by a System.exit() call a while back (not Ant's main, but
another). I was wrapping a local utility in an Ant task and while the task
ran and the tool did its job, Ant would just abort with no errors, no
messages, nothing. After a little fiddling I discovered it was a call to
exit(). Is the reason for Ant's main calling System.exit() simply to return
an exit code to the OS? That's what it looks like. A cursory glance at
Ant's Main.start() method looks like one could use the
additionalUserProperties element to pass a property like "exit=true" or
something like that and then Ant could check that before calling
System.exit().

Ant's Main.main calls System.exit, that is why.
