Using the Snippet Generator tool in Jenkins 2, I can setup a plugin like I would within a job, and then it will generate me the Groovy I can use in my Pipeline script.
But what if the plugin I am interested in instrumenting isn't listed in the "Sample Step" drop down in the Snippet Generator? How do I determine how to create a script block to instrument the plugin I want to use?
In my case, I would like to use the "Flexible Publish" plugin within my Pipeline script.
You can't use plugins which are not compatible with pipeline generally. Plugins need to be modified more or less to be compatible. See https://github.com/jenkinsci/pipeline-plugin/blob/master/COMPATIBILITY.md
To be complete you need to know that snippet generator only shows compatible plugins that declare a specific help page in plugin's code. If we take the example of docker-workflow plugin, you can see in the code that it defines a help page for DockerDSL, which means that a Snippet Generator will be available for DockerDSL step.
Therefore you should always check Jenkins plugins compatibility page (as arasio mentionned it) and not what you see in Snippet Generator.
