Whilst trying to run mvn grails:exec with more complicated requests it kept erroring:

Whilst trying to install the Nimble plugin for Grails using Maven I ran in to a spot of bother!

I’ve started investigating Grails for some projects and have been making some good headway and I like to use Maven for everything as it’s amazing, and generating projects is easy.

I need to write some backup software for our hosted Google Apps, so as we’re a Java shop I’m going to be using the Java API. Also we’re heavy users of Hudson and Maven so want to get the checked out source building with that.

There is a Google Code project called google-apis-mavenized which looks like it has done most of the work for us, but it does not build when it’s checked out.
