Off the top of my head, i wouldn't even bother writing a new plugin or updating one. Write a script in any language to collect all the information from each individual build/test and then aggregate that into a JUnit XML file.
Take a look at Tap plugin <https://wiki.jenkins-ci.org/display/JENKINS/TAP+Plugin>, it's similar to JUnit but simpler. and the artifact diff <https://wiki.jenkins-ci.org/display/JENKINS/Artifact+Diff+Plugin> plugin. Not sure if they will help you but i remember seeing these two when i was searching a few months ago. -- You received this message because you are subscribed to the Google Groups "Jenkins Developers" group.
