Keeping up with our goal to clean up some of the technical debt inside Jenkins Core and reduce the maintenance overheads, we are happy to report we were able to remove a long-deprecated Apache Commons Digester library. Jenkins Core does not depend anymore on Apache Commons Digester v.2.1, a version that has been released in 2010. Some plugins will require update to operate properly after the...

There are now three different Docker Hub repositories that are or have been used as the "official" Jenkins image. This article aims at providing a clarification about which one is the current official one (as of December 2018 :-)). The official one docker pull jenkins/jenkins i.e. https://hub.docker.com/r/jenkins/jenkins/ is the right repository to use. I also documented some time ago on my blog the recommended way to run Jenkins using...

Evergreen is a distribution of Jenkins we are working on that provides an easy to use and automatically upgrading experience. This year at the conference, there will be not just one, but two talks to present Evergreen to the Jenkins community: Continuously Delivering an Easy-to-Use Jenkins with Jenkins Evergreen, by R. Tyler Croy. Safely Upgrading Jenkins Every Single Day, by Baptiste Mathus. Tyler will present the overall Jenkins...

Jenkins Essentials has been renamed to Jenkins Evergreen since this was written. Jenkins Essentials is about providing a distribution of Jenkins in less than five minutes and five clicks. One of the main ideas to make this a reality is that Jenkins will be autoconfigured with sane defaults for the environment it is running in. We are happy to report we recently merged the change that provides...

For users of the weekly release, this means that Jenkins 2.54 must have a Java 8 runtime installed on the system in order to run. Those using the jenkinsci/jenkins:latest Docker container won’t...

Earlier this month, a full-day event about Jenkins Pipeline was organized in Toulouse, France with the Toulouse JAM. After a warm-up on the previous Tuesday where Michaël Pailloncy had given a talk at the local Toulouse Devops user group about Jenkins Pipeline ecosystem, we were ready for more digging :-). The agenda We had planned the day in two parts: Morning would be a more driven workshop with...

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...

Like for last year’s article about the same subject, yet another recent discussion about finally requiring Java 8 to run future versions Jenkins pushed me to gather some more factual data around it. What follows contains some opinions or statements which may not be seen as purely factual or neutral. Note that this represents by no mean the general position of the Jenkins governance board....
