JavaOne activities around Hudson

Posted by kohsuke on May 28, 2009 at 11:59 AM PDT

JavaOne is just a few days ahead now, so let me recap what's happening around Hudson during JavaOne.

On Sunday, we have Unconference (RSVP) and a party at the Thirsty Bear (RSVP to "RSVP-ThirstyBear2009 at sun dot com".) The great thing

Hudson swarm slave plugin

I run a budget-less Hudson cluster, just like many of you do, and one of the challenges is to have enough computing resources in a cluster.

Project of the day: SSH daemon for EC2 Windows AMIs

Posted by kohsuke on May 20, 2009 at 1:07 AM PDT

In my attempt to make Hudson EC2 plugin (which I blogged earlier) work with Windows AMIs, I wrote a little SSH daemon.

Hudson EC2 plugin

Continuous Integration often requires a heterogeneous environments; for example, the GlassFish build requires Linux, Solaris, and Windows, and the JDK build requires something like 10 different environments, each carefully created so that we can test what we need to test.

Unfortunately, heterogeneous environments reduce the resource utilization — you can easily have some Windows slaves

Hudson Selenium Grid Plugin

Posted by kohsuke on May 16, 2009 at 7:45 AM PDT

I've released href="http://wiki.hudson-ci.org/display/HUDSON/Selenium+Plugin">the

can start using Selenium Grid without installing it on individual
machines in the cluster manually.

This one is from Kiyotaka, who wrote a Hudson plugin called GCrawler.

GCrawler (1) searchs Google Code and discovers all Grails projects, (2) reads Subversion repository to figure out metadata, and

This is from Seiji Sogabe, who is a Hudson committer. He put together a chart of the hudson.war size from 1.100 to 1.300.

Hudson CLI and Groovy shell

Posted by kohsuke on May 2, 2009 at 8:26 AM PDT

"You can do everything from GUI" has always been one of Hudson's strengths, and we also have the REST API, but at the same time, CLI is also very useful for improving automation around administration, builds, and so on. So starting Hudson 1.302, I added a CLI agent to Hudson.
