Today I released a plugin that adds support for Microsoft's source control manager Team Foundation Server to Hudson (a continuous integration server). The plugin makes it possible to retrieve files and poll the server to detect changes on a project. If Hudson detects a change, a new build can be started automatically. Hudson will also display the changes that occurred in each build.
Configuring the plugin is easy as it is only requires the server URL and the path to the project. Hudson will take care of the rest, such as creating a workspace and work folder to store the files in.
The plugin supports both the command line client in the Team Explorer package from Microsoft and the command line client from Teamprise. An upcoming version of the plugin will add support for the opentf command line client.
So if you wanted to give Hudson a whirl but couldn't use it because you were using TFS, now is the chance to try it out! For more information about this plugin, check out the wiki. There are also several other .NET plugins for MSBuild, NAnt, NUnit, FxCop, StyleCop and compile warnings. I'm currently working on a plugin that integrates CodePlex into Hudson.
Update: The plugin can be downloaded here, or through the update manager in Hudson.
