I would get the IJavaProject associated with the resource change event
[see org.eclipse.jdt.core.JavaCore.create(IProject)] and then see if you
can inspect its build path through the IJavaProject API.
Does the resource delta include the .classpath file? I'd expect it
would; that way you can distinguish changes that affect build path from
other project changes.
Hope this helps,
Eric

I don't think there is any notification API at that level; that's why I
suggested getting the IJavaProject from the IProject in the delta.
You might have better luck by posting the question to the
eclipse.tools.jdt newsgroup; maybe the JDT gurus there know of an
alternative API that would help.
