Surya walked us through the dotCI source code yesterday, and a bunch of ideas about how to reuse pieces are discussed. The recording is on YouTube, and my notes are here....

Tomorrow in Jenkins office hours, Surya Gaddipati will be going over DotCi, a package of features that integrates Jenkins closely with GitHub, configuration via .ci.yml file in source tree, built-in Docker support and MongoDB backend. I think there’s a number of interesting pieces here that could be split into individual plugins for reuse, and possible alignment with existing efforts like Script Security plugin or Literate...

Today on IRC, I was asked how someone new to the project can get started working on Jenkins, when s/he has no particular preference or pet-peeve. This is a good question for which the project should have a canned answer ready, so here is one approach — adopt a plugin! Often, a Jenkins plugin gets developed by someone to scratch his own itch. That person shares...

+ One of the few plugins that I still personally maintain is Active Directory plugin. In the past few months, I’ve been making steady improvements in this plugin, thanks to various inputs and bug reports given to me from the ClodBees customers. One of the recent fixes was to get the "remember me" feature finally working for Active Directory. This requires a relatively new Jenkins 1.556,...

+ I recently had an opportunity to visit a big Jenkins user on site, and one of the things they’ve told me is that building projects in the Maven job type is substantially slower than doing the same with the freestyle project type. This is partly expected, because this job type does more for you. For example, it automatically archives your build artifacts, fingerprints all the...

(This is a guest post by Stephen Connolly) Every developer, at some stage, will be handed a project to maintain that somebody else was responsible for. If you are lucky, the developer will not have left the organization yet and you get a brief Knowledge Transfer as the developer packs up their desk before heading on to their new job. If you are unlucky, you...

This is a guest post by Mike Rowan, VP R&D at SendGrid. Q: Tell us a bit about what your service and plugin do. Who is it for? What are the highlights of your plugin? A: Loader.io is a simple-to-use cloud-based load testing service. The service is designed for developers and people who need to ensure applications are performing as they should. It allows developers to...

This Wednesday’s Jenkins office hours is all about the Git plugin refactoring that’s going on. Git plugin is one of the most popular plugins out there, and it’s been around for quite some time. Combine that with the fact that there are so many different ways to use Git, it was inevitable that Git plugin became quite a capable but complex plugin over time. It...

As the usage of Jenkins expands, we started seeing users who run multiple 100s of agents on one controller, and thus it became a lot more important for us to scale well to even larger number of agents. While I was looking at the thread dump of a large system, I started noticing that there are a large number of threads lying around pumping InputStream...

The last Jenkins office hour of the year hosts Robert Sandell and Tomas Westling, who will go over newly open-sourced metadata plugin from Sony Mobile Communications (more about this story on their website). This team from Sony Mobile has been known for several other popular plugins, including the Gerrit trigger plugin. And I think this latest batch of plugins will not disappoint! As I understand,...
