It’s been a long time coming, but, thanks to Jay, who’s really kicked some ass to make this happen, the long suffering Rcov port to JRuby finally is bearing fruit. The first gem is now available.
There are a few known issues. Performance isn’t that great. And there is some slight variation between what Rcov reports in JRuby vs. MRI. But Jay’s been using it in his build environment, and so should you. So go ahead and grab the gem and help us make it great!
