[news.eclipse.tools.gef] Attempting to export/deploy an Eclipse plugin I

[vijay.santhanam@xxxxxxxxx (Vijay Santhanam)]

Hi,

I've developed an Eclipse (3.5) plugin for my employer (a university) 
using Graphical Editing Framework (GEF).

Deploying the app should be as simple as pressing the "Export Wizard" link 
and entering an archive name and hitting "Finish".

But then I encounter the an error dialog protesting "Could not find one or 
more classes: "org.apache.tools.ant.launch.AntMain". Please check the Ant 
classpath."

But I've looked inside the Eclipse>Preferences>Ant>Runtime>ClassPath and 
found everything to be in order. I'm running OSX.

What's wrong? How do I set the class path so I can deploy my plugin.

Can anyone suggest any approach to investigate what's causing this problem?

Regards,
