The Job DSL plugin currently has support for configuring the ghprb plugin. But the config format for the ghprb plugin has changed a lot with recent versions which makes it hard for the Job DSL to support newer features while keeping compatibility with older versions.

It would be better to move the DSL support to the ghprb plugin by using the Job DSL extension point. That would assure that the DSL will always generate the correct configuration for the ghprb plugin.
