Is it possible to "clean workspace as root"?

[alfred.perlstein]

Our build process needs to create some files as root.

We are using sudo for this.

The problem we are having is that the jenkins system doesn't appear allow you to make your own "clean workspace" hook.

Because of this cleaning the workspace is run as "jenkins" and the "rm -rf" fails due to bad permissions.

Is there a way to override the "rm -rf" for clean workspace to use "sudo rm -rf" please?

thank you,
