eclipse:add-maven-repo doesn't update correct Eclipse property file

Under Eclipse 3.0.1 the eclipse:add-maven-repo fails. From email:

Hi all,

I was wondering if the eclipse:add-maven-repo goal was failing for anyone else? I am scripting an install of Eclipse 3.0.1, and notice that the plugin seems to be referring to the wrong path, maybe used in one of the Eclipse 3.0 Milestone builds: /.metadata/.plugins/org.eclipse.jdt.core/pref_store.ini whereas it seems like it should be writing to .metadata/.plugins/org.eclipse.core.runtime/.settings/org.eclipse.jdt.co
re.prefs..?
