Recently when trying to debug an issue I was having in Grails, I found that the root cause was actually a Groovy bug. After checking the bug tracker, I discovered that the bug was fixed in a future version of Groovy. Unfortunately this would mean having to update Grails, but I couldn’t find a definitive answer on WHICH Groovy version went with a specific version of Grails. Turns out there is no single source that lists this data, even independently for each version. I was able to find a blog post that covered up to Grails 1.3.7 but it hadn’t been updated since 2010. Using that post as a starting point, I decided to compile a list of the Grails-Groovy versions, and the documentation/source of where I gathered the info. I started with Grails 1.2.0, and only included full releases.
If there are any errors/updates, please let me know. I’ll do my best to keep this info up-to-date!
