Discard old builds: how to plug a different BuildDiscarder?

[martinda]

Hi,

I would like to implement a slightly modified build retention policy, and I do not get how to plug a different BuildDiscarder into the core. For example, if I have a modified version of:
https://github.com/jenkinsci/jenkins/blob/master/core/src/main/java/hudson/tasks/LogRotator.java

then I'd like to register it so it becomes available as an option. How would I do that?

Thanks,
Martin

Have an inner DescriptorImpl class (of the appropriate descriptor type) and add an @Extension annotation.
