Uhh, I don't know. All the groovy knobs on Jenkins (especially the cloudbees enterprise one) and nexus enabled a ridiculous amount of customisation which while it made me a load of consultancy money, I think taught me the lesson that most of the time it's better to adapt your apps to your CI and infra, than to try and adapt your CI and infra to your apps.

I much prefer GitLab + k8s to the nightmare of groovy I provided over the last decade anyway..
