Spotbugs is a utility used in Jenkins and many other Java projects to detect common Java coding mistakes and bugs. It is integrated into the build process to improve the code before it gets merged and released. Findsecbugs is a plugin for Spotbugs that adds 135 vulnerability types focused on the OWASP TOP 10 and the Common Weakness Enumeration (CWE). I’m working on integrating...

Google Summer of Code (GSoC) is as program where students are paid a stipend by Google to work on a free open source project. Students work on the project full-time for four months (May to August). Mentors are actively involved with students starting at the end of February when students start to work on and submit their applications. (see the timeline) We are looking for project ideas and mentors...

In September 2019 we announced support of GitHub as a source of documentation for the Jenkins Plugin Site. Thanks to Zbynek Konecny and Olivier Vernin and other contributors, now it is possible to store plugin documentation right inside plugin repositories instead of Jenkins Wiki which was historically difficult to maintain for plugin maintainers and for the Jenkins infrastructure team. This blogpost may be interesting to plugin maintainers and...

This is one of the Jenkins project in GSoC 2019. We are working on adding support for Multi-branch Pipeline Jobs and Folder Organisation in GitLab. The plan is to create the following plugins: GitLab API Plugin - Wraps GitLab Java APIs. GitLab Branch Source Plugin - Contains two packages: io.jenkins.plugins.gitlabserverconfig - Manages server configuration and web hooks management. Ideally should reside inside another plugin with name GitLab Plugin. In future, this...

I have been working on improving the performance of the Role Strategy Plugin as a part of my Google Summer of Code project. Since there was no existing way to measure performance and do benchmarks on Jenkins Plugins, my work for the first phase of the project was to create a framework for running benchmarks in Jenkins plugins with a Jenkins instance available. To make our job...

Two months ago I published an introductory article on the journey of becoming a Jenkins contributor. In that first article, the jenkins.io site was reviewed, learning about the multiple ways in which we can participate and contribute. Then, a first—​basic—​contribution I made to the site repository was described. Now, in this new article we will be exploring more advanced contributions, committing code to the actual Jenkins core. Getting started...

As a software engineer, for many years I have used open source software (frameworks, libraries, tools…​) in the different companies I have worked at. However, I had never been able to engage in an open-source project as a contributor, until now. Since I made my first—​ridiculously simple—​commit into Jenkins, six months ago (in September, 2018), I have been attempting to contribute more to the Jenkins project. However, contributing...

This is a joint blog post prepared by the Java 11 Support Team: Adrien Lecharpentier, Ashton Treadway, Baptiste Mathus, Jenn Briden, Kevin Earls, María Isabel Vilacides, Mark Waite, Ramón León and Oleg Nenashev. We have worked hard for this and it’s now here. We are thrilled to announce full support for Java 11 in Jenkins starting from Jenkins 2.164 (released on Feb 10, 2019) and LTS...

Mentors get actively involved with students starting at the end of February when students start to apply (see the timeline). We are looking for mentors and project ideas to participate in the 15th edition of the...
