San Francisco Jenkins Meetup - Wednesday, April 13th

Engine Yard!We're happy to announce that there'll be a Jenkins meetup in San Francisco on Wed., Apr 13th, generously hosted by Engine Yard. The meetup will start at 6:30 - you can find more information here. Dr Nic Williams of Engine Yard will talk about their use of Jenkins with Ruby, and Kohsuke will give an update on the JRuby plugin development work he and cowboyd have been working on. If you're interesting in giving a short talk on your usage of Jenkins, plugin work, or whatever, there should be time for an open mic. Hope to see you there!

Windows installers are now available

Good portion of Java developers use Windows, so we tend to think the opposite is true, that a good portion of Windows folks use Java. But this is not true.

As Jenkins gains traction among .NET developers, it's becoming increasingly clear that Java is very alien to them. They naturally have no idea of what a war file means, and often don't even have Java installed, and so it was just not easy enough for them to start using Jenkins.

I'm happy to report that I've finally fixed this problem with the new Windows installer. It is primarily packaged as an MSI file — a common format that seasoned Windows devs/admins are familiar with. It can, for example, be deployed remotely on a large number of servers via Active Directory remotely. Or you can just double-click it to install it interactively. It bundles JRE, so no separate Java installation is needed.

The package also contains the bootstrap setup.exe, to install .NET 2.0 runtime if it's not installed yet. Between that and JRE, it got all the dependencies covered. I tested that by installing it on a fresh Windows XP install.

So I hope this makes Jenkins more attractive to .NET and other developers who live and die by Windows.

The polls are open for the Jenkins Logo Contest!

After a number of absolutely fantastic logo submissions from a number of designers, I'm extremely pleased to open the polls on the vote for the brand new Jenkins logo!

The thumbnails do not do any of these logos justice in my opinion, so I recommend opening each logo up in its own tab to get the full effect :)

I plan to end voting March 28th at 12:01 UTC.

Updated Usage Stats Available!

Updated usage statistics are now available at This data has been scrubbed of distinguishing information as much as possible, filtered for installations we've seen at least twice a month with at least one job set up, and split up into monthly JSON files. Starting with August, we only have data on installations of version 1.368 or later - before that, reports go to the old Oracle-owned server, and we aren't able to retrieve them. So that's why you'll see a fairly hefty drop in install count, etc from July to August.

I haven't had a chance to do any analysis to speak of on the data. I intend to get the plugin usage spreadsheet updated n the next few days, but I wanted to make this data available to you all ASAP. If you come up with any interesting analysis or use of the data, please let us know!

Upcoming Jenkins events in Tokyo

I'll be visiting Tokyo again for the week of 2/21 for a number of events.

Tokyo Jenkins User Meetup

The Japanese Jenkins user community may not be as visible from outside but very strong. This is the 2nd meet up in Tokyo, and once again we maxed out the 80 people room capacity in just a few days (but you can still RSVP for the social event after the meetup.) This meetup is focused on Java & Jenkins, so we have a number of speakers lined up to discuss hwo they use Jenkins in their Java projects. This will be the first user meetup event after the name has changed to Jenkins.

CloudBees Jenkins training in Tokyo

I'll deliver this one-day training course, all about Jenkins from the setup to continuous deployment to code analysis. If you are interested, you can find more details about this.

Japan Grails/Groovy User Group (JGGUG)

Jenkins internally use Groovy a lot in many places (as well as some of its peripheral tools depend on Groovy.) So I'll be speaking in the JGGUG meetup event, on behalf of the Jenkins project, and highlight those usages and how much we all love Groovy. Yes, I do.
