It is interesting having an open source project that is sufficiently old to start generating "lore" of some form or another. Jenkins is starting to get to be that age, having been started over 6 years ago. One of the most commonly asked questions, is about Jenkins' use of "blue balls" to indicate success by default. This is enough of an "issue" for some users...

Until now, Jenkins plugins written in Java or Groovy could only be built with Maven, using the maven-hpi-plugin to generate a proper manifest and archive which Jenkins can consume. But starting now, you can also use Gradle! See the wiki for information on how you can use Gradle and the new gradle-jpi-plugin to build, test and release your Java or Groovy Jenkins plugin....

As we approach the holiday season, which is when people start to feel more charitable, at least in the U.S. So I’d like to make one more plea, that the Jenkins project needs your help in paying its expense, and that we are still about $1000 shy of the goal we need to get to. So if you can, please help us by donating...

+ There’s currently a survey running to get a better sense of our use base. Those inputs help us steer the effort wisely, so we appreciate your taking time to fill it in. The result would be more useful if larger number of people participate, so feel free to encourage others to fill it in as well. In the same spirit of the fundraising drive in...

Since the end of April, Jenkins has been officially part of the SPI (Software in the Public Interest), an umbrella organization which offers a useful level of legal status for the project. Up until recently we had not taken proper advantage of this new legal umbrella, thankfully that’s changed as we’re now capable of accepting donations! For the project this is a big step forward as it will allow us to...

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...

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...

We’re happy to announce that there’ll be a Jenkins meetup in San Francisco on Wed., Apr 13th, generously hosted by Engine Yard. The meetup will start at 6:30 - you can find more information here. Dr Nic Williams of Engine Yard will talk about their use of Jenkins with Ruby, and Kohsuke will give an update on the JRuby plugin development work he and...

Good portion of Java developers use Windows, so we tend to think the opposite is true, that a good portion of Windows folks use Java. But this is not true. As Jenkins gains traction among .NET developers, it’s becoming increasingly clear that Java is very alien to them. They naturally have no idea of what a war file means, and often don’t even have Java...
