In my daily work I often have to create or modify Jenkinsfiles and more often than I would like, I make mistakes. It is a very tedious workflow when you make a change to your Jenkinsfile, create a commit, push the commit and wait for your Jenkins Server to tell you, that you have missed a bracket. The Command-line Pipeline Linter (https://jenkins.io/doc/book/pipeline/development/) does a great...

Kohsuke here. This is a message for my fellow Jenkins developers. Jenkins has been on an amazing run, but I believe we are trapped in a local optimum, and losing appeal to people who fall outside of our traditional sweet spot. We need to take on new efforts to solve this. One is “cloud native Jenkins” that creates a flavor of Jenkins that runs well on...

In January we announced the release of SCM API 2.0. After the original release was published we identified four new high-impact issues. We decided to remove the new versions of the plugins from the update center until those issues could be resolved. The issues have now been resolved and the plugins are now available from the update center. Summary for busy Jenkins Administrators Upgrading should make multi-branch projects much better....

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...

With more than a thousand public plugins in the Jenkins community now, it should come as no surprise that some of them are no longer actively maintained. Plugin authors move on when they change jobs, or lose interest in the plugin, and that’s fine. Plugins are hosted on the Jenkins project infrastructure after all, and when a maintainer moves on, others can continue their...

This is a guest post by Manuel Recena Soto (aka recena). Users of the plug-in know that it has undergone very important changes in the last two years. Unfortunately, some of these changes resulted in regressions for some users that weren’t properly addressed in subsequent releases. Many users were therefore forced to keep using an older release of the plugin to keep their instances running. To fix...

Depending on how long you have used Jenkins, your...
