I would like to run snippets of groovy code (that access classes defined in the workflowLibs.git repository) via the Jenkins CLI using the groovy and groovsh command support.

Currently Jenkins CLI starts executing the groovy code, but cant find the relevant classes (defined in workflowLibs.git repo).

I think this is just a matter of having the right classpath setup in the groovy/groovysh backend on the Jenkins server that is accessed via the CLI (as is done auto-magically for the script area within the workflow job definition).
