Following today's (Thursday 2nd June) upgrades to JIRA and FishEye the JBoss Community Team are proud to announce the availability of Crucible and GreenHopper. We've also taken the opportunity to rename fisheye.jboss.org to source.jboss.org since both FishEye and Crucible are now served from that domain:
http://source.jboss.org - click on the Projects menu item to see projects configured for Crucible and the Reviews menu item for a list of code reviews
In both cases project teams should contact the JBoss Community Team to enable the features for their projects. Crucible code reviews are intended to be used for periodic reviews of the code in addition to GitHub's code review functionality which is generally used when accepting patches.
