what kind of example(s) are you specifically looking for?
the pipeline syntax generator can be used to create the snippet needed for the Jenkinsfile. under sample step select step
and find the Artifact Resolver step in the list of build steps. fill out the fields accordingly and click the generate button to get the snippet.
if you're looking for something else, let me know. i will be cutting a release w/ this in it once i make sure i have all the prereqs to do so taken care of.
