grails errors upgrading from 2.1.1 to 2.3.0

Hello,

I'm hoping someone may have some insight on how to resolve this issue.  I've been trying to upgrade from grails 2.1.1 to 2.3.0 on IntelliJ 11.1.5 and keep running into problems.

At first I had a missing method Exception for conf/groovy-starter.conf where the app would not even begin to compile, but then found a tip to remove javadoc and sourcs jars:

$ rm dist/grails-*-javadoc.jar

$ rm dist/grails-*-sources.jar

which seem to at least begin the build, however I now get this error:

junit#junit-dep;4.10: not found

I've tried a number of things already:

-download and adding the jar manually

-editing buildconfig.groovy for dependancies, plugins

-invalidating caches

with no effect. Any help would be much appreciated.

Thanks.
