Hi,
I have a 3.2.2 based plug-in that after installed, the value set for the
Ant home under Window->Preferences->Ant->Run time->Classpath->Ant Home
Entries(Default) is changed, causing Ant build to be broken.
After the installation is done the value previously set to the location
of the org.apache_ant_1.7.0 plug-in (eclipse\plugins) is changed to
(..configuration\org.eclipse.osgi\bundles\578\1\.cp\) which happens to
be an older version of Ant (1.5.2).
Note that plug-in that is being installed, does not depent on ant
itself, it only requires the org.eclipse.osgi plug-in.
Any ideas on how to prevent this from happening ?
Thanks,
-MD

Hi Darin,
The plug-in is something that I wrote, so I know that does not pack an
ant jar with it. The only connection that I could find so far is that
my plug-in requires the org.eclipse.osgi to be present, and from there
it points to a ant.jar file that is part of the eclipse configuration
directory, rather that taking one from the plugins directory.
As I was trying to rule out conflicts with third party plug-ins or
corrupt jar files, I tested and was able to duplicate the problem even
on a fresh install on the 3.2.2 SDK. And I still have the problem, and
the following error shows up on the log file.
