We just released security updates to Jenkins, versions 2.44 and 2.32.2, that fix a high severity and several medium and low severity issues. For an overview of what was fixed, see the security advisory. For an overview on the possible impact of these changes on upgrading Jenkins LTS, see our LTS upgrade guide. I strongly recommend you read these documents, as there are a few possible side...

This is a guest post by Sam Van Oort, Software Engineer at CloudBees and contributor to the Jenkins project. Today I’m going to show you best practices to write scalable and robust Jenkins Pipelines. This is drawn from a combination of work with the internals of Pipeline and observations with large-scale users. Pipeline code works beautifully for its intended role of automating build/test/deploy/administer tasks. As it is pressed into...

As we get closer to Blue Ocean 1.0, which is planned for the end of March, I have started highlighting some of the good stuff that has been going on. This week was 10 steps forward, and about 1.5 backwards…​ There were two releases this week, b19 and b20. Unfortunately, b20 had to be released shortly after b19 hit the Update Center as an incompatible API change in a 3rd party plugin...

As we get closer to Blue Ocean 1.0, which is planned for the end of March, I have started highlighting some of the good stuff that has been going on, and this week was a very busy week. A new Blue Ocean beta (b18) was released with: Parametrized pipelines are now supported! i18n improvements Better support for matrix and the evil (yet somehow still used) Maven project type (don’t use it!) SSE fixes...

This is a guest post by Liam Newman, Technical Evangelist at CloudBees. Introduction With all the new developments in Jenkins Pipeline (and Declarative Pipeline on the horizon), it’s easy to forget what we did to create "pipelines" before Pipeline. There are number of plugins, some that have been around since the very beginning, that enable users to create "pipelines" in Jenkins. For example, basic job chaining worked well in many cases, and the Parameterized Trigger...

In the next few months, Jenkins will require Java 8 as its runtime. Back in last November, we discussed interesting statistics showing that Jenkins was now running Java 8 on a majority of its running instances. Timeline Here is how we plan to roll that baseline upgrade in the next few months. Now: Announce the intention publicly. April, 2017: Drop support for Java 7 in Jenkins weekly. With the current rhythm, that means...

The regressions discovered after release have now been resolved and this post has been updated with the correct plugin version numbers. See this post for more details. We are announcing the SCM API 2.0.x and Branch API 2.0.x release lines. Downstream of this there are also some great improvements to a number of popular plugins including: GitHub Branch Source BitBucket branch source Git Mercurial Pipeline Multibranch GitHub Organization Folders There are some gotcha’s that Jenkins administrators will need to...

As we get closer to Blue Ocean 1.0, which is planned for the end of March, I figured it would be great to highlight some of the good stuff that has been going on. It’s been a busy-as-usual week as everyone comes back from vacation. A couple of new betas went out this week. Of note: input to Pipelines is now supported, a much asked for feature (see below) A...
