[platform-ant-dev] How do I run the org.eclipse.ant.core plugin in a run

[Matt_Conway@xxxxxx]

I'm trying to hack the org.eclipse.ant.core plugin to get it working with 
ant 1.5.  Unfortunately I must be doing something wrong because I can't 
seem to run my local version (unedited even) in a runtime-workbench 
instance.  I use CVS to checkout org.eclipse.ant.core as a project, add 
ECLIPSE_HOME/plugins/org.apache.ant_1.4.1/ant.jar as a build library, 
rebuild the project, "Create Plug-In JARs" from plugin.xml (neccessary?), 
set the Plugin dev preferences for the target platform to have all plugins 
but org.eclipse.ant.core, then Run->Debug As->Runtime-workbench.  The 
workbench instance starts up ok, but when I run a simple build.xml inside 
it, AntRunner fails to instantiate InternalAntRunner - a java.lang.Error 
gets thrown due to the use of the ant classes like Project, etc - I 
printed the stack trace below.   There must be something simple I'm doing 
wrong - probably to do with pointing the running plugin to ant.jar (I _do_ 
do so in the Ant preferences page in the runtime-workbench instance - in 
the debugger I can access the Project class in the display pane no 
problem).  Any help appreciated,
