  Today on IRC, I was asked how someone new to the project can get started working on Jenkins, when s/he has no particular preference or pet-peeve.

• Maven job type performance improvements in Maven plugin 2.2

  + I recently had an opportunity to visit a big Jenkins user on site, and one of the things they’ve told me is that building projects in the Maven job type is substantially slower than doing the same with the freestyle project type. This is partly expected, because this job type does more for you. For example, it automatically archives your...

• Reducing the # of threads in Jenkins: SSH agents

  As the usage of Jenkins expands, we started seeing users who run multiple 100s of agents on one controller, and thus it became a lot more important for us to scale well to even larger number of agents. While I was looking at the thread dump of a large system, I started noticing that there are a large number of threads...

• Office hours next week: metadata plugin

  The last Jenkins office hour of the year hosts Robert Sandell and Tomas Westling, who will go over newly open-sourced metadata plugin from Sony Mobile Communications (more about this story on their website).

• Building Jenkins plugins with Gradle

  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...
