We recently released version 1.3 of Declarative Pipelines, which includes a couple significant new features. We’re going to cover these features in separate blog posts. The next post will show the new ability to restart a completed Pipeline run starting from a stage partway through the Pipeline, but first, let’s look at the new sequential stages feature. Sequential Stages In Declarative 1.2, we added the ability to define stages...

About API tokens Jenkins API tokens are an authentication mechanism that allows a tool (script, application, etc.) to impersonate a user without providing the actual password for use with the Jenkins API or CLI. This is especially useful when your security realm is based on a central directory, like Active Directory or LDAP, and you don’t want to store your password in scripts. Recent versions of Jenkins also make...

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 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...

In the meantime, Jenkins contributor Baptiste Mathus took some time to introduce and demonstrate...

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...

This week we have a Jenkins & Java 10 Online Hackathon. This is an open online event, where we work together on Jenkins core and plugins in order to find and fix compatibility issues, share experiences and have some fun. 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...
