Error updating jars with Eclipse GWT 2.0 plugin

Question

Ever since updating our project to the newest version of the Eclipse GWT plugin and GWT 2.0 we get an error when starting Eclipse.

This is the error message:

An internal error occurred during: "Updating project/war/WEB-INF/lib with jars from GWT - 2.0.0".

Here is the exception message:

java.lang.IllegalArgumentException: Attempted to beginRule: R/, does not match outer scope rule: P/project

Everything works just fine, I just get this error when Eclipse starts up. I've done everything I can think of to fix it, but it still happens.

Any ideas? Is anyone else getting this error?

Answer 1

This was seen when, for instance, using a too old version of subclipse (see this thread, and bug 129045 or bug 128709)

This is linked to a change in the ISchedulingRule modifyRule(IResource resource) of the Resources component.

So are you using a compatible version of eclipse (i.e 3.5x) with GWT2.0?
