Liquibase Runner Plugin 1.2.0
It's been a while since Jenkins introduced a new build configuration system – Pipeline: https://jenkins.io/doc/book/pipeline/
It's getting used more and more. The difference is: in a pipeline you don't have GUI-configurable steps, you define it with a Groovy script. So, plugins export functions.
I think, it would be a great improvement if Liquibase plugin for Jenkins supported the Pipeline.
