+ About two years ago, we bumped our runtime JRE requirement from Java5 to Java6. And so the time has come once again for us to finally move on to Java7. Because of all the new language features, many of us the developers really wanted to move right on to Java8, but after much discussion we settled to move to Java7 first and then to...

This is a guest post from Owen Mehegan (aka autojack) In 2014 Google announced that they will be shutting down their OpenID 2.0 authentication endpoint and replacing it with Google+ Sign-in, a library built on top of OpenID Connect. The old Google endpoint will shut down on April 20th, 2015! Accordingly, if you are using the Jenkins OpenID plugin to authenticate users with the ‘Google...

Jenkins started with a notion of jobs and builds at heart. One script is one job, and as you repeatedly execute jobs, it creates builds as records. As the use case of Jenkins gets more sophisticated, people started combining jobs to orchestrate ever more complex activities. A number of plugins have been developed to enable all sorts of different ways to compose jobs, and many...

Jesse and I will walk through the source code of the workflow plugin, highlights key abstractions and extension points, and discuss how they are put together. If you are interested in developing or retrofitting plugins to work with workflows, I think you’ll find this session interesting. The event will be on Google Hangout tomorrow. The time of the day is the same as usual office hours....

(This is a guest post from Michael Neale) Recently at the Docker Conference (DockerCon) the Docker Hub was announced. The hub (which includes their image building and storage service) also provides some "official" images (sometimes they call them repositories - they are really just sets of images). So after talking with all sorts of people we decided to create an official Jenkins image - which is hosted...

This is a guest post from Tom Fennelly Over the last number of weeks we’ve been trying to "refresh" the Jenkins UI, modernizing the look and feel a bit. This has been a real community effort, with collaboration from lots of people, both in terms of implementation and in terms of providing honest/critical feedback. Lots of people deserve credit but, in particular, a big thanks...

The other day I was explaining how to implement a new workflow primitive to Vivek Pandey, and I captured it as a recording. The recording goes over how to implement the Step extension point, which is the workflow equivalent of BuildStep extension point. If you are interested in jumping on the workflow plugin hacking, this might be useful (and don’t forget to get in touch...

+ One of the current efforts under way in the dev list is driven by Tom Fennelly et al, who is working on introducing a series of small ball improvements to the user interface in Jenkins. If this is something you are interested in (and who aren’t?), you should see Kevin Burke’s manifest that sets out the plan of attack, and This mega thread on...

Over the past 30 days or so, the acceptance test project has made a great progress. This project consists of a reusable harness that can be used by plugin developers and users to write functional test cases. These tests can be run against Jenkins instances that are deployed in all sorts of different ways, and can interact with complex real fixtures. These tests can be...

This week I’m going to do an office hour on how to write an acceptance test in Jenkins acceptance test harness. The event is on Wednesday 11am PT. This new Selenium-based test harness is full of page objects and other abstractions that let you write blackbox integration tests on Jenkins and its plugins, as well as how they behave under various environments. Unlike our regular office...
