Until now, Jenkins plugins written in Java or Groovy could only be built with Maven, using the maven-hpi-plugin to generate a proper manifest and archive which Jenkins can consume. But starting now, you can also use Gradle! See the wiki for information on how you can use Gradle and the new gradle-jpi-plugin to build, test and release your Java or Groovy Jenkins plugin....

It’s not often that I get to use that much hyperbole in a Jenkins blog post, but I think in this case it’s allowable. A journey that started over a year ago by Charles Lowell has reached a new level, thanks to lots of help from Kohsuke along with Hiroshi Nakamura and Jørgen Tjernø. As of today, with Jenkins 1.438, you can now download and...

[Editor’s Note: This is a guest post from Jenkins community member Tom Rini] Alternatively: How to make your parallel jobs kick one last job at the end Many of us have had occasion to think: "I could make this project build quicker if I could just run parts in parallel and then one final job to wrap it up." Well, good news! Jenkins is here to help!...

[Editor’s Note: For the past few weeks Jenkins community member Charles Lowell has been working with Kohsuke on adding support for building plugins in Ruby. As part of this effort, Charles has been hosting weekly hack sessions via WebEx] As always, last night’s Ruby Plugins hack session was a pleasure. Below is a quick notation of what items were discussed and/or accomplished followed by next...

Updated usage statistics are now available at https://jenkins-ci.org/census 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...

In late 2008, the Hudson team released version 1.264 which added an anonymous reporting feature (you can opt-out in the "Manage Hudson" screen). The reporting feature has been sending information back to the Hudson team to help us understand how Hudson is used in aggregate; the info being reported includes the number of jobs configured, agent configurations, what plugins (and what versions of those...

For as long as Hudson’s had a plugin model and development community, we’ve provided source code and binary hosting through our Subversion repo at java.net. But what if you’re a plugin developer and you don’t want to use Subversion? Well, we have an alternative for your source code: host it with Hudson on GitHub. To get this in place, send an email to dev@hudson.dev.java.net (or...

In my capacity as Build Guy at Digg, I’ve written up a blog post on our new continuous deployment/code review/pre-tested commit workflow. We’re using a combination of Hudson, Git and Gerrit, Selenium and more to make sure that every change going to Digg’s new site has been thoroughly tested. Read the whole post, with all the juicy details over on Digg’s Technology Blog!...

Hudson, like all web applications, is not immune from vulnerabilities that could open up attack vectors for malicious use. What puts Hudson in a league of its own compared to others is its ability to execute arbitrary commands on agent machines, or in the case of the EC2 plugin, execute arbitrary commands "in the cloud." In light of all this, Hudson is quite secure...
