Yesterday, Kohsuke announced that the 'jruby' branch of jenkins-core had been merged to master. This doesn’t mean that we’re done and that you can go forth and write pure ruby plugins…​ not by any stretch of the imagination. Instead, what it does mean, is that the Jenkins mainline is much more friendly to runtime analysis of classes with which it is not familiar. The problem When analyzing...

We’ve done meetups, we’ve done sessions, we’ve done workshops, now it’s about time we went ahead and did user conference don’t you think? Our pals over at CloudBees (Harpeet specifically) have taken the initiative in starting to organize just that: a Jenkins User Conference on October 2nd. If you have your calendar at the ready, you’ll notice that October 2nd is the Sunday before JavaOne kicks...

Let me preface this entire post with this: I love Contegix. While working on some infrastructure tasks I had long-since put-off for the Jenkins project, I noticed something this weekend that scared the hell out of me. At some undetermined time, our MirrorBrain installation stopped redirecting to our mirror network. Absolutely zero downloads were being redirected, meaning that cucumber, the 1U machine graciously colocated by Contegix had served up far more bits than...

You know that the night is going to be productive whenever @kohsukekawa shows up, and last night was no exception. We talked about problems on the horizon, potential solutions, and then I spent the last half hour ripping a bit of code. The truth of the matter is that most of the changes that have to be done to Jenkins core have already been made,...

We have released 1.409.1, our first long-term support (LTS) release, from the Jenkins project. The idea of the LTS release is to provide a second release line the favors more stability and bug fix only maintenance. This release line branches off from a bit old Jenkins release (in this case 1.409), and we will only put important backported bug fixes. We’ll keep releasing 1.409.2, 1.409.3,...

I’ve just added three events coming up in the next few weeks to the Jenkins calendar. Conveniently, they are all events I’ll be attending while traveling around Western Europe! The Cologne JUG is having a meetup on Saturday, June 25th, starting at 2pm. We’ll be talking about Jenkins, maybe doing some coding, and then heading out for drinks and more talk! You can find more...

This post is long over-due and I really apologize for that. Some months ago we put out the call for "more agent machines!" through the mailing lists, sky-writers and twitter. We had a serious problem, for a continuous integration project, a large number of our plugins and dependencies weren’t being built in a continuous and automated fashion! We had some builds on a couple of flakey machines on home...

[Editor’s Note: This is a guest post from Jenkins community member Tom Rini] Alternatively: How to make your parallel jobs kick one last job at the end Many of us have had occasion to think: "I could make this project build quicker if I could just run parts in parallel and then one final job to wrap it up." Well, good news! Jenkins is here to help!...
