Ant build classpath jar generates "error in opening zip file"

Question

I have a project built in eclipse with a dependencies on 3rd party jars. I'm trying to generate a suitable build file for ant - using eclipses built-in export->ant buildfile feature as a starting block.

When I run the build target I get the following error:

[javac] error: error reading /base/repo/FabTrace/lib/apache/geronimo/specs/geronimo-j2ee-management_1.0_spec/1.0/geronimo-j2ee-management_1.0_spec-1.0.jar; error in opening zip file

And the whole build file (auto-generated by eclipse) looks like this: (NB: the error above always references the first jar listed in the classpath)

    <property environment="env"/>

    </target>

</project>

(I know there's eclipse specific stuff in here. But I get the same results with or without it.)

I've done ye old google search and trawled around without success.

I can confirm that all the jars do really exist. I've also tried from the commandline and as sudo - again, same results.

Any help would be greatly appreciated.

Cheers

As per Martin Clayton's suggestions, my previous comment is copied below as an answer.

"Sigh. I'd figured that because I'd removed the first jars that originally caused this problem (I wasn't even convinced I really needed them any more) and the problem just moved to the next jar... well, that made me suspicious of a systemic fault. Turns out I did in fact have aload of garbage jars on the classpath. Must have screwed up a download or something at some point. Anyway, all fixed now. Cheers"
