A bug was introduced in Jenkins versions 1.645 and 1.642.2 which caused Jenkins to send anonymous usage statistics, even if the administrator opted-out of reporting usage data in the Jenkins web UI. If you are running one of the affected versions, the best/easiest solution is to upgrade. The bug does not affect Jenkins 1.653 or newer, or Jenkins LTS 1.642.4 or newer. If you cannot upgrade, it is possible to immediately disable...

The student projects we are primarily interested in would improve the overall Jenkins user experience...

On December 15, the Toulouse JAM was co-hosted with the Toulouse JUG and Toulouse DevOps. Indeed it made sense since Jenkins is written in Java, makes use of Groovy code in many places (system groovy script, job dsl, workflow…​), and it also made sense to co-organize with the local DevOps community since Jenkins is also a great tool to enable Continuous Integration, Continuous Delivery and automation in general. There were 103 RSVPs, with...

As I mentioned in yesterday’s post, we’re planning a "Contributor Summit" on February 1st, after FOSDEM 2016 (January 30th/31st), to focus on Jenkins 2.0. Since many of us are already planning, the Monday following the event turned out to be the ideal time to discuss 2.0. If you’re not already familiar with some of the key proposals that were put forth, you can review them...

Special thanks to the JAM organizers and co-organizers who made it all happen in these cities: Lima, Peru St.Petersburg, Russia Toulouse, France Bay Area, CA On December 9 Lima...

While we are gearing up for FOSDEM 2016 early next year in Brussels, I wanted to remind the Jenkins community about our Travel Grant Program. We’re a little late on mentioning it, but the board has allocated the money to help Jenkins contributors travel to Brussels to participate in FOSDEM and the Jenkins Contributor Summit which we will be hosting the day after, Feb...

A lot of people are using the Workflow plugin, but as with any scripting environment, users often have to start from scratch and learn the same lessons and shortcuts that other users have already learned. While there are blog posts from developers and users in various places, and some samples in the Workflow plugin documentation, more examples and tips and tricks are always, always...
