This was actually a bug I wanted to fix with 3.2.2-4. It is fixed on
amd64. I tried that. But I can reproduce the bug on i386. The fix seems
to be in. I need to investigate that more...


Cheers,
Michael

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.
	(such as eclipse)

Hi,
Debian Eclipse and Ant apparently don't play together very well.
Will you handle this for lenny?
Since Ant has this omnipresent role in Java development, this bug IMHO
is release critical.

I downloaded ant 1.6.5 and changed my eclipse ant settings to point to
it, but it didn't help either; eclipse won't open or parse ant build.xml
files. (Note that I still have ant 1.7 on my system as well).
I also tried the merging trick mentioned, neither helped.

Error is:
java.lang.NoClassDefFoundError: org.apache.tools.ant.Main
just as with the other submitters of this bug.

best regards,
Erich Schubert

Date: Mon, 10 Nov 2008 09:18:40 +0100

Hi, I just want to confirm the mail by Bob Black. 
I used to run etch here at work, switched to lenny 
for openjdk and then eclipse started behaving funny. 
Some problemes were with plugins, and they were fixed
by upgrading plugins from eclipse, but then ant files
couldn't be used. Eclipse said it couldn't find 
tasks in them and the .log complained of class not found 
for ant classes. 

Then I did what Bob Black said and now it works. The only 
difference is this is lenny, not ubuntu.

Thanks all. I agree this bug is very annoying.
