This blog post gives an introduction to the new design for the login and signup forms and Jenkins is (re)starting pages introduced in Jenkins 2.128. The first part of the blog post is an introduction to the new design and UX for Jenkins users. The later part is talking about extensibility in a more technical manner, aimed at plugin developers. Overview The recent changes to some core pages...

Last week I participated in the Jenkins & Java 10 Online Hackathon. It was my first Jenkins hackathon and I roped in Jonah Graham to do some pair-programming. The hackathon featured JDK Project Jigsaw committers Mandy Chung and Paul Sandoz, as well as Jenkins creator Kohsuke Kawaguchi. It was a great opportunity for me to learn a lot about Jenkins and Java 10. Why Java 10? With the Java 8 EoL data looming, the...

I use macOS day to day, and often struggle to keep my devtools up to date. This isn’t any fault of packaging or tools, more just that I get tired of seeing the beachball: The demands on dev machines grow, developers are now working across a more diverse set of technologies than just a JVM or a single scripting language these days. This keeping up to date is...

(adapted from this blog post by Daniel Nurmi) As more and more Jenkins users ship docker containers, it is worth thinking about the security implications of this model, where the variance in software being included by developers has increased dramatically from previous models. Security implications in this context include what makes up the image, but also the components of the app that get bundled into...

Everybody is welcome to join, independently of their Jenkins experience and amount of time they have available. After the kick off on Monday Jenkins contributors have been working on Java...

A couple of weeks ago, Tyler mentioned some developer improvements in Essentials that had been recently introduced: the ability for ci.jenkins.io builds to get deployed automatically to an “Incrementals” Maven repository, as described in JEP-305. For a plugin maintainer, you just need to turn on this support and you are ready to both deploy individual Git commits from your repository without the need to run heavyweight traditional Maven releases, and to depend directly on similar commits...

This sort of slid under the radar in the middle of some bigger changes for the JEP-202 reference implementation, so I wanted to call it out now. Arguably this could deserve a retroactive JEP, though I would rather fold it into a JEP for JENKINS-49651 (see below). As of Jenkins 2.118, or plugin parent POM 3.7, you can mark any Java member (class, method, constructor, field, or I suppose also...
