DISCLAIMER: I'm running ubuntu 7.10

Any new info on the issue?  (I'm not sure it's i386 specific?)

Adding ant-launcher.jar to plugins/org.apache.ant_1.6.5/META-INF/MANIFEST.MF 
allowed me to launch (default) ant tasks.  (basically following 
debian/patches/eclipse-ant-manifest.dpatch)

That still left me with the problem that eclipse couldn't generally 
parse ant build.xml files.

After poking around for some time I just threw up my hands and
created a "combined" jar file with the contents of both ant.jar
and ant-launcher.jar and used it in place of the (symlink)
/usr/lib/eclipse/plugins/org.apache.ant_1.6.5/lib/ant.jar

Eclipse seems to be behaving perfectly fine now.


After my adventures I'm wondering if it would make sense to:
) Update to eclipse 3.3
) Upgrade the eclipse plugin to a version specifically for (ant) 1.7
) Make an ant 1.6 package available for packages that require it.
