Ant: Jar task fails with NoClassDefFoundError [message #65069]

I am trying to get my Ant build file to work from within Eclipse. I'm
using Eclipse 2.1.1 build 200305071103 with Ant 1.5.3 (April 16 2003).
When the build gets to creating a jar file it fails with:

jar:
[copy] Copying 8 files to S:\dev\eCommerce\bilby\build
[jar] Building jar: S:\dev\eCommerce\bilby\build\bilby.jar
BUILD FAILED: java.lang.NoClassDefFoundError
Total time: 14 seconds

The other targets work ... compiling, running tests etc, just not jar.
The build works when run outside Eclipse.

I have copied the latest ant.jar, optional.jar and junit.jar into the
plugin directory. I am running this with JDK 1.4.1_01.

Any ideas? Is there another jar I need to add to the Ant runtime classpath?

Have you tried running with -debug or -verbose to determine the exact class
that is not found?

You do not need to do this.
