POTD: submit a patch to Jenkins, and let him test it for you

October 8th, 2012

Here’s my 2nd after-JavaOne “project of the day” Jenkins plugin. This has been in the back of my mind for quite some time, but it took this gentleman to grill me on this feature during JavaOne for me to finally put it together — so thank YOU for doing that. although I didn’t catch your name.

The plugin is called the “patch parameter” plugin. This plugin lets you submit a patch when scheduling a build, and that gets applied to the checked out source tree before a build would commence. Any failure to apply a patch will result in a build failure.

This plugin can be used for a “pre-tested commit” workflow. You can work on a change locally, have the diff tested on the server, then if you are satisfied, you can commit it. I can imagine this would be also an interesting building block for integration with code review tools.

I should also note that we have the Subversion Merge plugin for a different approach to a similar problem, and distributed VCS can generally do this better (for example I do one for Git in CloudBees Validated Merge plugin.)
