| Issue using AntRunner inside a plugin [message #272406] |

I am trying to use the AntRunner class in org.eclipse.ant.core to run a
build script from within a plugin. The function this is in is called from
the "start" function of the plugin activator. The code is as follows:
try{
antRun.setBuildFileLocation(installTarget);
antRun.setArguments(arg);
antRun.run();
}catch(Exception e){e.printStackTrace();
throw new Exception("Install Failed");}
(antRun was declared as a new AntRunner previous to this code)
I have added org.eclipse.ant as a dependency for the plugin this is in.
The problem I am having is that when I package/export the plugin and try
to test it, I get a classnotfound style exception on AntRunner - however I
am using classes from two other plugins in the activator and elsewhere
without problem. I have tried packaging the class I am using AntRunner in
into its own jar and using the extraClassPathEntries extension point to
add it to the ant classpath without any change. The other plugins I am
using classes from are those that are dependencies of the plugin when the
project if first created - ant is the first one I tried to add. I did
follow the steps to export (Organize manifest, externalize strings, check
build cnfiguration, and then export), so I don' think th eproblem is there.
So what I want to know is what step in using AntRunner within an eclipse
plugin am I missing?
Thanks for any help

A little more clarification: I have tried to use the import packages
feature as well, and I have tried manually adding "org.eclipse.ant.core"
to the "uses" section of the Manifest file for the package which the class
using AntRunner is in. I have also looked at the dependencies that were
part of the default plug-in project (and are working) and can see no
differences in how they are setup compared to the dependency on
org.eclipse.ant.core. I am using a new eclipse environment (Ganymede)
which is updated, and no other plugins have been installed (Its the Java
dev version). I have verified that org.eclipse.ant.core is one of the
installed plugins. I cannot modify org.eclipse.ant.core, so Buddy
classloading wouldn't work - and when I tried to add an entry to use the
"global" policy the manifest file did not indicate that it recognized the
"Eclipse-BuddyPolicy" entry as an entry. From the error it seems to be
searching the plugin for a source file for AntRunner - though I can't see
a difference between my use of AntRunner and the Activator's use of Bundle
Context, which the plugin has no problems finding. The exact error is:
!ENTRY org.eclipse.osgi 4 0 2009-07-20 18:28:37.687
