Watch Me Code, Episode 5 pipeline shared libraries

Watch Me Code - Episode 5

The build is defined in the vars/asfMavenTlpStdBuild.groovy file, that relies on the jenkinsEnv singelton.

Ideally you would put vars/jenkinsEnv.groovy in a separate repository (or at least a separate branch) and define two shared libraries:

  1. The shared library that defines jenkinsEnv
  2. The shared library that defines asfMavenTlpStdBuild

This way, to migrate to a different Jenkins master, we just need a different jenkinsEnv singleton that respects the same API contract.
