Join me for Jenkins World 2016

Tue, 07/26/2016 - 02:00
Jenkins World, September 13-15 at the Santa Clara Convention Center (SCCC), takes our 6th annual community user conference to a whole new level. It will be one big party for everything Jenkins, from users to developers, from the community to vendors. There will be more of what people always loved in past user conferences, such as technical sessions from users and developers, the Ask the Experts booth and plugin development workshop, and even more has been added, such as Jenkins training pre-conference, workshops and the opportunity to get certified for free. Jenkins World is a not-to-be-missed. For me, the best part of Jenkins World is the opportunity to meet...

Blue Ocean July development update

Tue, 07/19/2016 - 02:00
The team have been hard at work moving the needle forward on the Blue Ocean 1.0 features. Many of the features we have been working on have come a long way in the past few months but here’s a few highlights: Goodbye page refreshes, Hello Real Time updates! Building upon Tom's great work on Server Sent Events (SSE) both Cliff and Tom worked on making the all the screens in Blue Ocean update without manual refreshes. SSE is a great technology choice for new web apps as it only pushes out events to the client when things have changed on the server. That means there’s a lot less traffic going between your browser and...

Sending Notifications in Pipeline

Mon, 07/18/2016 - 02:00
This is a guest post by Liam Newman, Technical Evangelist at Cloudbees. Rather than sitting and watching Jenkins for job status, I want Jenkins to send notifications when events occur. There are Jenkins plugins for Slack, HipChat, or even email among others. Note: Something is happening! I think we can all agree getting notified when events occur is preferable to having to constantly monitor them just in case. I’m going to continue from where I left off in my previous post with the hermann project. I added a Jenkins Pipeline with an HTML publisher for code coverage. This week, I’d like to make Jenkins to notify me when builds start and when...

New packages for Jenkins 2.7.1

Thu, 07/14/2016 - 02:00
We created new native packages for Jenkins 2.7.1 today. These replace the existing packages. Due to a release process issue, the packaging (RPM, etc.) was created the same way as Jenkins 1.x LTS, resulting in problems starting Jenkins on some platforms: While we dropped support for AJP in Jenkins 2.0, some 1.x packages had it enabled by default, resulting in an exception during startup. These new packages for Jenkins 2.7.1, dated July 14, have the same scripts and parameters as Jenkins 2.x and should allow starting up Jenkins without problems. If you notice any further problems with the packaging, please report...

Jenkins 2 hits LTS

Thu, 07/07/2016 - 02:00
It’s been almost three months since we’ve released Jenkins 2.0, the first ever major version upgrade for this 10 year old project. The 2.x versions since then has been adopted by more than 20% of the users, but one segment of users who haven’t seen the benefits of Jenkins 2 is those who has been running LTS releases. But that is no more! The new version of Jenkins LTS release we just released is 2.7.1, and now LTS users get to finally enjoy Jenkins 2. This release also officially marks the end-of-life for Jenkins 1.x. There won’t be any future release of...

Publishing HTML Reports in Pipeline

Fri, 07/01/2016 - 02:00
This is a guest post by Liam Newman, Technical Evangelist at Cloudbees. Most projects need more that just JUnit result reporting. Rather than writing a custom plugin for each type of report, we can use the HTML Publisher Plugin. Let’s Make This Quick I’ve found a Ruby project, hermann, I’d like to build using Jenkins Pipeline. I’d also like to have the code coverage results published with each build job. I could write a plugin to publish this data, but I’m in a bit of hurry and the build already creates an HTML report file using SimpleCov when the unit tests run. Simple Build I’m going to use the HTML Publisher Plugin to...

GSoC: External Workspace Manager Plugin alpha version

Thu, 06/30/2016 - 02:00
Currently it’s quite difficult to share and reuse the same workspace between multiple jobs and across nodes. There are some possible workarounds for achieving this, but each of them has its own drawback, e.g. stash/unstash pre-made artifacts, Copy Artifacts plugin or advanced job settings. A viable solution for this problem is the External Workspace Manager plugin, which facilitates workspace share and reuse across multiple Jenkins jobs and nodes. It also eliminates the need to copy, archive or move files. You can learn more about the design and goals of the External Workspace Manager project in this introductory blog post. I’d like to announce that an alpha version of...

Migrating from chained Freestyle jobs to Pipelines

Wed, 06/29/2016 - 02:00
This is a guest post by R. Tyler Croy, who is a long-time contributor to Jenkins and the primary contact for Jenkins project infrastructure. He is also a Jenkins Evangelist at CloudBees, Inc. For ages I have used the "Build After" feature in Jenkins to cobble together what one might refer to as a "pipeline" of sorts. The Jenkins project itself, a major consumer of Jenkins, has used these daisy-chained Freestyle jobs to drive a myriad of delivery pipelines in our infrastructure. One such "pipeline" helped drive the complex process of generating the pretty blue charts on This statistics generation process primarily performs two major tasks, on rather large sets of...

Faster Pipelines with the Parallel Test Executor Plugin

Thu, 06/16/2016 - 02:00
This is a guest post by Liam Newman, Technical Evangelist at Cloudbees. In this blog post, I’ll show you how to speed up your pipeline by using the Parallel Test Executor Plugin. So much to do, so little time…​ Every time I’ve moved a team to continuous integration and delivery, one problem we always encounter is how to run all the tests needed to ensure high-quality changes while still keeping pipeline times reasonable and changes flowing smoothly. More tests mean greater confidence, but also longer wait times. Build systems may or may not support running tests in parallel but only on one machine even while other lab machines sit idle....

Jenkins Pipeline Scalability in the Enterprise

Wed, 06/15/2016 - 02:00
This is a guest post by Damien Coraboeuf, Jenkins project contributor and Continuous Delivery consultant. Implementing a CI/CD solution based on Jenkins has become very easy. Dealing with hundreds of jobs? Not so much. Having to scale to thousands of jobs? Now this is a real challenge. This is the story of a journey to get out of the jungle of jobs…​ Start of the journey At the beginning of the journey there were several projects using roughly the same technologies. Those projects had several branches, for maintenance of releases, for new features. In turn, each of those branches had to be carefully built, deployed on different platforms and versions, promoted...

GSoC Project Intro: Support Core Plugin Improvements

Tue, 06/14/2016 - 02:00
About me I am Minudika Malshan, an undergraduate student in Computer Science and Engineering from University of Moratuwa, Sri Lanka. As a person who is passionate in open source software development and seeking for new knowledge and experience, I am willing to give my contribution for this project. LinkedIn | Twitter Abstract The Support-Core Plugin provides the basic infrastructure for generating "bundles" of support information with Jenkins. There are two kinds of bundles. Automatic bundles: Bundles which are generated and get saved in $JENKINS_HOME/support once per hour starting 15 seconds after Jenkins starts the plugin. The automatic bundles are retained using an exponential aging strategy. Therefore it’s possible...

Save up to 90% of CI cost on AWS with Jenkins and EC2 Spot Fleet

Fri, 06/10/2016 - 02:00
This is a guest post by Aleksei Besogonov, Senior Software Developer at Amazon Web Services. Earlier this year, we published a case study on how Lyft has used Amazon EC2 Spot instances to save 75% on their continuous delivery infrastructure costs by simply changing four lines of code. Several other EC2 customers like Mozilla have also reduced costs of their continuous integration, deployment and testing pipelines by up to 90% on Spot instances. You can view the current savings on Spot instances over EC2 On-demand instances using the Spot Bid Advisor: AWS Spot instances are spare EC2 instances that you can bid on. While your Spot instances may be terminated...
