As of eclipse 3.6, i am getting this error during our automated build process:

[taskdef] Could not load definitions from resource net/sf/antcontrib/antlib.xml. It could not be found.

cruisestart:
[java] java.lang.NoClassDefFoundError: org/eclipse/equinox/launcher/Main

What is the value of ${equinoxjar}?

The class org/eclipse/equinox/launcher/Main is contained in the equinox launcher (org.eclipse.equinox.launcher) not in org.eclipse.osgi.
