This plugin allows Hudson to invoke Rake tasks as build steps.
The plugin detects the ruby VM installed on the host and it allows you to include new instances. You can configure Hudson to allow that each project will select the installation that will use.

This plugin works as other builders like Ant builder or Gant builder. You just need to specify the Rake tasks to run but you can also configure other Rake options.
