At Jenkins World last month, we continued the tradition of "lunch-time demos" in the Jenkins project’s booth which we started in 2016. We invited a number of Jenkins contributors to present brief 10-15 minute demos on something they were working on, or considered themselves experts in. Continuing the post-Jenkins World tradition, we also just hosted a "Jenkins Online Meetup" featuring a selection of those lunch-time demos. I would like...

After a few months of work on its key features, I’m happy to announce the 1.2 release of Declarative Pipeline! On behalf of the contributors developing Pipeline, I thought it would be helpful to discuss three of the key changes. Parallel Stages First, we’ve added syntax support for parallel stages. In earlier versions of Declarative Pipeline, the only way to run chunks of Pipeline code in parallel was to use the parallel...

While at Jenkins World, Kohsuke Kawaguchi presented two long-time Jenkins contributors with a "Small Matter of Programming" award: Andrew Bayer and Jesse Glick. "Small Matter of Programming" being: a phrase used to ironically indicate that a suggested feature or design change would in fact require a great deal of effort; it often implies that the person proposing the feature underestimates its cost. — Wikipedia In this context the "Small Matter" relates to Jenkins Pipeline and...

This is a guest post by Brian Dawson on behalf of CloudBees, where he works as a DevOps Evangelist responsible for developing and sharing continuous delivery and DevOps best practices.

This is a guest post by Mark Waite, who maintains the git plugin, the git client plugin, and is a technical evangelist for CloudBees, Inc. The Jenkins project booth at Jenkins World 2017 will include the "Pull Requests Corner", recruiting new Jenkins contributors. We think there are many people who will attend the conference without realizing how easy it is to help the Jenkins project, and how much the help is...

This is a guest post by Alyssa Tong, who runs the Jenkins Area Meetup program and is also responsible for Marketing & Community Programs at CloudBees, Inc. Jenkins World 2017 is a week away. Like last year, we are bringing back the lunch-time demos in the Jenkins project’s booth. These are quick 15 minute How-to demos by Jenkins experts. These demos will not be live streamed, nor recorded, so come early to...

This is a guest post by Andrew Bayer, who is one of the authors of the Declarative Pipeline plugin, and is a software engineer on the Pipeline team at CloudBees, Inc. A year ago at Jenkins World 2016, we unveiled Declarative Pipeline, a structured way to define your Pipeline. It’s been a great year for Declarative and Pipeline in general, with the release of Declarative Pipeline 1.0 in February, multiple releases since...

This is a guest post by Guy Salton, Sr. Professional Services Engineer for CA BlazeMeter. Jenkins Pipeline is an important Jenkins feature for creating and managing a project in Jenkins. This is opposed to the traditional way of creating a Jenkins project by using the Jenkins GUI. When running your open-source load test, Jenkins Pipeline enables resilience, execution control, advanced logic and Version Control management. This blog post will explain...

There are upcoming changes in Jenkins "core" which may require extra steps when upgrading Jenkins. If you use configuration management for Jenkins agents, please read this announcement carefully. If you have ever seen messages like "Channel is already closed" or "Remote call failed" in your build logs, you have already met Jenkins Remoting. Remoting is an agent executable (aka slave.jar) and a library implementing the communication layer between...

This is a guest post by Pui Chee Chen, Product Manager at Microsoft working on Azure DevOps open source integrations. Recently, we improved the Azure Credential plugin by adding a custom binding for Azure Credentials which allows you to use an Azure service principal (the analog to a service or system account) via the Credentials Binding plugin. This means it’s now trivial to run Azure CLI commands from a Jenkins Pipeline. We...
