<p>When I launch an ant script from Eclipse 3.4.x it prints the output to console until certain stage. After that it often hangs (wait forever). Last lines that I see at the screen (console) - partial output from my obfuscator.</p>

<p>Under Eclipse 3.3.2 everything works fine (the same project, workspace, settings, JVM etc.).</p>

<p>Does anybody have the same issue? Any thoughts how to fix it?</p>

One possible cause is that you are
running out of memory
Also try to run ant with the
```
-diagnostics
```
option.
You can check your
memory usage
and your
eclipse.ini
.
Another classic culprit is a
blocking access to a locked resource
(like an access to a file already being used by another process): try to close a many applications you can and relaunch ant.
