Recently, the Jenkins project announced the release of Jenkins 2.0, a first major release after 10 years and 655 weekly releases. This has been a major milestone for Jenkins and its growing community of developers, testers, designers and other users in the software delivery process. With its rising popularity and wide adoption, the Jenkins community continues to grow and evolve into the millions. Jenkins community meetup activity has risen to an...

A few weeks ago, my colleague Brian Dawson and I were invited to present on Scaling Jenkins for Continuous Delivery with Microsoft Azure in Microsoft’s Reactor space. Azure is Microsoft’s public cloud offering and one of the many tools available to Jenkins users for adding elastic compute capacity, among other things, to their build/test/deploy infrastructure. While our presentations are applicable to practically any cloud-based Jenkins environment, Thiago Almeida and Oguz Pastirmaci from Microsoft...

We just released security updates to Jenkins that fix a number of low and medium severity issues. For an overview of what was fixed, see the security advisory. One of the fixes may well break some of your use cases in Jenkins, at least until plugins have been adapted: SECURITY-170. This change removes parameters that are not defined on a job from the build environment....

Over the past 10 years, Jenkins has really grown to a de-facto standard tool that millions of people use to handle automation in software development and beyond. It is quite remarkable for a project that originally started as a hobby project under a different name. I’m very proud. Around this time last year, we’ve celebrated 10 years, 1000 plugins, and 100K installations. That was a good time to retrospect, and we...

Last week, the infrastructure team identified the potential compromise of a key infrastructure machine. This compromise could have taken advantage of, what could be categorized as, an attempt to target contributors with elevated access. Unfortunately, when facing the uncertainty of a potential compromise, the safest option is to treat it as if it were an actual incident, and react accordingly. The machine in question had access to binaries published...

Those of you who routinely apply all plugin updates may already have noticed that the version numbers of the plugins in the Pipeline suite have switched to a 2.x scheme. Besides aligning better with the upcoming Jenkins 2.0 core release, the plugins are now being released with independent lifecycles. “Pipeline 1.15” (the last in the 1.x line) included simultaneous releases of a dozen or so...

In this post I will show how you can make your own DSL extensions and distribute them as a plugin, using Pipeline Script. A quick refresher Pipeline has a well kept secret: the ability to add your own DSL elements. Pipeline is itself a DSL, but you can extend it.
