Couple of Groovy static analysis tools

I stumbled across a couple of static analysis tools for Groovy/Grails that mirror our Java-based ones. Might be useful to throw into our CI config…

1) CodeNarc – Like Checkstyle but for Groovy.
2) Grails Test Coverage plugin – a nice Grails plugin that wraps Cobertura, which already supports Groovy. (We use Emma for our Java.)
