We were pretty hooked onto using some plugins which are not supported in pipelines anymore and would like to implement their usage in shared-libraries of our pipelines. One of the main items required for that would be to get hold of Jenkins Instance, can someone share a way to do that ?

• Are there any restrictions or proper way to get hold of "Jenkins.getActiveInstance()" under "src" or "vars" folder ?

I have tried to get Jenkins.getActiveInstance() under src code as well vars code but it returns null, am I missing something here? any help will be appreciated.

thanks
