I am working on the custom bundle of Jenkins based on the 2.0 baseline. In this custom bundle I would like to extend the functionality of the default UpdateCenter.
- Ability to extend REST API (new commands for very custom cases)
- Ability to manage update sites from the code according to the installation settings
- Ability to alter UpdateCenter UIs and maybe tweak the installation Wizard
According to the current Jenkins design, it cannot be done via a classic extension point in a plugin, but it can be done in a library. Since UpdateCenter can unlikely provide extension points for our cases, it seems the best way would be to override the UpdateCenter instance.
I propose to add a system property, which would allow to instantiate Jenkins with a custom UpdateCenter.
