(dear reader, this list is long outdated - please go to https://objectpartners.com/2015/05/14/list-of-groovy-versions-for-each-version-of-grails/ for a list that's regularly updated!)
As this is my first blog post, hello world!
Now that the formalities have been dealt with, here's a question I've had today: what version of Groovy does my Grails installation contain? Ok, that one is easy, hardly worth blogging about, but here's the quick answer anyway: start your favorite Groovy/Grails shell (two obvious candidates are grails shell and grails console) and execute the following:
println org.codehaus.groovy.runtime.InvokerHelper.version
But unfortunately, my Groovy version did not support a feature I wanted, so the next question was, what version of Grails would I have to upgrade to in order to get my feature? After some digging on the Grails JIRA, I compiled a table of Groovy/Grails versions that hopefully will help somebody else as well.
