Hudson or Jenkins Parameterized Builds using dynamic choices

Question

Is there a plugin or ability to write some type of JSP or script to allow a Hudson or Jenkins parametrized build to generate the dropdown choices dynamically.

For example if we have a single parametrized build that operates on one of the workspaces being managed in Hudson (where we'd rather not create a job per workspace). We "create" new workspaces daily and we'd like the parametrized build to be able to display those workspaces in a dropdown box as a parameter to that job.

It'd be nice if I could just embed a JSP script or something that would be executed to return a list of choices.

The exact behavior you are looking for doesn't exist yet as far as I'm aware, but the Extended Choice Parameter plugin comes close.

If that doesn't work, it would also not be a very complicated plugin to write. If you want to take a stab at writing it yourself, you can take a look at this introduction to the plugin environment and this more comprehensive overview of plugin development (there's much more information there than you'd actually need; you might want to just extend the Extended Choice Parameter instead, since it already has the infrastructure set up).

If you don't want to do it yourself, you could create a feature request in Jenkins' issue tracker (assuming you don't find another feature request that would also satisfy your needs; I didn't see one, but I don't know much about your environment), and somebody else might pick it up.

In the meantime, I think you could use the Extended Choice Parameter, combined with a script that automatically wrote to a file whenever anybody created a new workspace.
