Continuous Information - Jenkins Newsletter vol. 4

Volume 4 of Continuous Information came out last night. It contains insights and highlights from founder Kohsuke, the latest growth stats, upcoming event info, Jenkins resources, and more.


  • Jenkins has nearly 20,000 more active installations than it had last June, up from 43,500 to more than 61,000
  • Nearly 100 plugins have been added since late last Fall when we did the last Jenkins survey. Now there are more than 730 plugins
  • Bay Area JUC (Oct 23), JUC Israel (Jun 6) and several other Jenkins events around the world have open registration
  • Latest, greatest Jenkins improvements include a new LTS based on 1.509, more context menu improvements, and master/slave data transfer performance improvement
  • There's also a Security advisory out recommending upgrade to at least 1.502
  • A plethora of Jenkins and Continuous Delivery resources

Giving Back to the Community: 3 Ways to Keep Jenkins Growing

With more than 600 plugins, Jenkins has a vibrant community and we're dependent on YOU to keep it that way. Here are 3 ways you can give back to the community to ensure that everyone benefits and Jenkins keeps growing...

Giving it back to the community #1: vendor+community=win

Jenkins is becoming ubiquitous enough that tool vendors and service providers often find their users asking them to provide Jenkins plugins. The challenge for these companies is that they don’t necessarily possess the necessary Jenkins expertise to do one.

Here at the Jenkins project, what we are trying to do is to work with these people to deliver a plugin. It gets the job done a whole lot more quickly if the vendor brings in their expertise on their tool/services and we bring in our expertise on Jenkins plugin development.

For example, we recently worked with SOASTA to help them open-source the plugin they developed in house, then help them add a whole bunch of new functionalities. By open-sourcing a plugin in the Jenkins project, vendors win as the community helps fix bugs and improve plugins. The Jenkins project wins by building relationship with vendors. And finally the users win by having more integrations.

Registration & Call for Papers Open for JUC Palo Alto

This year, the West Coast Jenkins User Conference will be in Palo Alto rather than San Francisco. If you’re nearby – or even if you’re not – join Kohsuke and other fellow developers for a solid day of Jenkins.

The Call for Papers is open until June 9 (scroll to bottom of page for form).

Munich Hackathon

It's been a while we had a hackathon in Germany. Let's get together, get some coding done, and get to know fellow Jenkins developers! The date is June 15th Saturday.

TNG Technology Consulting, where Stefan Wolf (dependency graph viewer plugin, etc) works, will be hosting us (thanks!)

We'll try to arrange some themes or agenda, based on who's coming and how many of us will be there. For example,

  • If there are many people who have never done a plugin development, we can do a plugin development tutorial.
  • If we see a concentration of devs in a specific area of Jenkins (say mobile), we can try some focused development in a specific area.
  • If you have things you need from the core to do what you want, this is the chance to get that implemented on the spot!
  • If you want to see a certain development happen in Jenkins but don't know how, please make a pitch to us in the form of presentations (short or long) would be welcome

Finally, assuming there's interest, we'll head out somewhere for a dinner afterward.

Neuroscientists embrace continuous integration served by Jenkins

As recently exemplified by several reports on this blog, automation tools such as continuous integration servers, that help to defuse the exploding complexity of software under the ever-increasing pressure to deliver, are steadily gaining well-deserved mindshare in the industry.

However, it is not just developers of enterprise software who need solutions to the complexity problem. Scientists are arguably even worse off: most of them are not trained as software engineers, yet, in the last decades, creating custom software has become an integral part of virtually any research activity, be it data analysis, simulation or experiments. Frequently, there is a great emphasis on numerical accuracy and reproducibility of results, which requires extensive testing. As a coup de grâce, most publicly funded research projects are running on tight budgets, excluding the possibility of hiring professional contractors to outsource required software development work.

Enter Jenkins the Butler!
