Jenkins Sao Paulo Meetup this weekend

I'm going to visit Sao Paulo once again this weekend to attend the second annual Jenkins users meet-up. It's a whole day free event Saturday full of Jenkins goodness.

You'll hear from a number of active Jenkins folks, and I'll be presenting about what CloudBees (where I currently work) has contributed to the Jenkins project, including recent new OSS plugins and some services. I'm also stuffing my suitcase with lots of give-aways, including Jenkins stickers and popular Jenkins bobble heads. I don't intend to bring anything back to the U.S.

Bobble head

The morning half of the event is a cross-atlantic hackathon between Brazil and Copenhagen. you can check what's being planned on the western side of the ocean and the eastern side of the ocean. The afternoon half is a series of presentations. Please come join us. I'm really looking forward to seeing you!

I'll be in Sao Paulo for the whole Sunday and Monday as well.

Jenkins User Conference 2013 Palo Alto Wrap-up

It's been a month now, but I realized that I've never posted a wrap-up post of JUC 2013. So in the spirit of "better later than, never", here it goes.

First of all, I wanted to thank everyone who came. More than 400 of you came, and another 600 signed up for live streaming of events (and I know some people watched those live streams past midnight in their local time zone!). I did my part in signing bobble heads and answering questions, and I was able to finally put faces to some of the people who I actively interact in the community but never met before.

I tried to take as many pictures as I can, and Lisa and Alyssa had posted their pictures as well. If you have your pictures, please share it with us! My favorite is Jenkins cupcake:

Summary Report: Git Repository Disruption Incident of Nov 10th

As reported in various places, there was an incident in early November where commits in our Git repositories have become misplaced temporarily by accident. By the mid next week we were able to resurrect all the commits and things are back to normal now.

As there are many confusions and misunderstandings in people’s commentary, we wrote this post to clarify what exactly happened and what we are doing to prevent this.


In the early morning of Nov 10th 2013, one of the 680 Jenkins developers had mistakenly launched Gerrit with a partially misconfigured Gerrit replication plugin, while pointing Gerrit to his local directory that contains 186 Git repositories cloned from the Github Jenkins organization. These repositories were checked out about 2 months ago and weren’t kept up to date. Gerrit replication plugin had then tried to “replicate” his local repositories back to GitHub, which it considers mirrors, by doing the equivalent of “git push --force” instead of regular push.

Experimental Plugins Update Center

Lately there has been several cases where we wanted to deliver beta versions of the new plugins to interested users.

To simplify this, we have created a new "experimental" update center, where alpha and beta releases of plugins will be available. Users who are interested in downloading them can go to "Plugin Manager", then to the "advanced" tab, and type in in the update center URL field.

When you are looking for the "available" tab, plugins that are experimental are marked accordingly to help you decide which ones to install. Once you install the beta plugins that you wanted, you can switch back to the default update center.

If you are developing plugins and you want to distribute experimental plugins, all you have to do is to put "alpha" or "beta" in the version number of pom.xml. The backend infrastructure takes care of the rest.
