Proper use of grails:exec

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

After some playing about, I finally found the correct runes

Woo hoo!

Latest release information is not available for plugin ‘nimble’, specify concrete release to install

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

An investigation in to the available plugins yielded

nimble <0.3-SNAPSHOT (?)> -- Nimble


So a bit of reading and thinking and specifically talking to another Grails developer, I found the solution

Integrating Grails and Maven

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.
