Jenkins

Welcome back to the Plugin of the Month series, where we highlight useful and impactful plugins from the Jenkins ecosystem. For June 2026, we’re featuring the Build Discarder Plugin. Do you maintain a Jenkins server with thousands of active users? And even more builds? Spring cleaning? Or you just want to keep things neat and tidy? A global configuration for your build items can help, because this is one of those things that is easy to forget until it becomes a problem. This month, we are highlighting the Build Discarder Plugin. What is the Build Discarder Plugin? Jenkins comes with a built-in build discarder that can...

Have you ever pushed a Jenkinsfile change only to discover a syntax error after Jenkins has started running the pipeline? Or had to wait through a full CI cycle just to learn that you have missed a closing bracket? I have built jenkinsfilelint to catch these problems early — right at commit time, before the code ever reaches the CI. What is jenkinsfilelint? jenkinsfilelint is a command-line tool and a pre-commit hook that validates Jenkinsfiles through your real Jenkins instance. Instead of trying to parse Jenkins Pipeline syntax locally — which is notoriously difficult since Jenkinsfiles are Groovy-based with server-side resolution — it...

We’re happy to announce that the most requested feature for the Pipeline Graph View plugin (and for Blue Ocean before it) is finally here: a new layout that renders nested pipelines in full detail. Pipelines with nested parallel stages (like CI → Run tests → Frontend → cypress above) or nested sequential stages (like CD above) benefit from this change the most. Upgrade the Pipeline Graph View plugin to version 918.vf572523124f2 or later to use the new layout. Previously, a fixed column-based layout was used for displaying the pipeline graph. It supported one level of parallel nesting and the display of...

Hey everyone! I’m Mohammed Faheem, a software engineering student and a Google Summer of Code 2026 contributor with Jenkins. This summer, I’ll be working on Jenkins email notifications using Outlook SMTP with OAuth, focused on adding a secure OAuth-based authentication flow for sending email notifications through Microsoft Outlook SMTP, as well as supporting other OAuth providers. Project Description This project aims to enhance the Jenkins Email Extension (email-ext) plugin by introducing OAuth support for SMTP using the client credentials flow. As providers continue deprecating legacy username/password authentication, Jenkins users need a modern and reliable way to keep CI/CD notifications working. The work includes supporting...

Hello everyone, I’m Daniele, an Italian computer science student, and this summer I’ll be working on the AI ​​Chatbot to Guide User Workflow plugin during GSoC 2026. I started contributing to Jenkins many months ago, and after following the official communication channels, I noticed how difficult it can be for beginners to understand the functionality of complex software like Jenkins. My goal is to create a plugin that’s useful for Jenkins beginners, but can also help every developer debug their own failed Jenkins executions, reducing the time spent fixing a specific error and maximizing productivity. The plugin will allow you to connect the current application...

cdCon 2026 just wrapped up in Minneapolis and this included announcing the winners of the Continuous Delivery Foundation and Jenkins Community Awards. The CD Foundation provides awards for the Top CDF ambassador, contributor, documenter, and end user. Anyone that is part of the CD Foundation can be nominated for these. Additionally, as a graduated project, Jenkins has three of its own awards: Most Valuable Jenkins Advocate Most Valuable Jenkins Contributor Jenkins Security MVP Thanks to the voters and to everyone who nominated candidates. We extend special thanks to all the nominees for their work in Jenkins. The project thrives because of its community, and the award recipients are outstanding...

Hello everyone! I’m Mallikarjun G D, a second-year B.E. Computer Science and Design student at Dayananda Sagar College of Engineering, Bengaluru (India). This summer I’m a GSoC 2026 contributor with Jenkins, working on Continue AI-Powered Chatbot for Quick Access to Jenkins Resources. Project Description This project is a continuation of a Jenkins plugin that embeds an AI chatbot into the Jenkins UI, allowing users to query documentation, plugin details, and community resources without leaving Jenkins. My work this summer extends that base with three core features: An LLM-as-a-Judge evaluation pipeline using a curated golden dataset and DeepEval metrics to score retrieval and answer quality. GraphRAG via NetworkX for...

Hello everyone! I’m Vatsal Verma, a final-year student and a Google Summer of Code 2026 contributor with Jenkins. This summer, I’ll be working on Retool jenkins.io website Success Stories which aims to modernize the tech stack, improving the submission workflow, and enhancing the overall UI/UX experience of the website. Project Description This project aims to migrate the Jenkins.io Success Stories website from Gatsby to Vite, enabling faster builds, improved developer experience, and better performance. It focuses on modernizing the UI/UX with a responsive, accessible, and user-centric design. A key objective is redesigning the story submission workflow by moving from Decap/Netlify CMS to a...

Welcome back to the Plugin of the Month series, where we highlight useful and impactful plugins from the Jenkins ecosystem. For May 2026, we’re featuring the Coverage Plugin. Quality assurance is a pillar of modern CI/CD. Knowing how much of your code is actually tested—and how effectively those tests find bugs is crucial for maintaining a healthy codebase. This month, we are highlighting the Coverage Plugin, a comprehensive solution for collecting, aggregating, and visualizing code and mutation coverage reports in Jenkins. What is the Coverage Plugin? The Coverage Plugin is the modern successor to several older, format-specific coverage plugins. Instead of installing a different plugin for every...
