Is there a way how to convert Jenkins project into Pipeline?

Question

I do have existing project which has a few steps and I would like to have exactly same thing with multibranch support. Multi branch project is looking good but I need to use Pipeline and create Jenkinsfile, but when it comes to Pipelines I do struggle to find good documentation and examples.

So an idea is that it would be really handy, if I can convert existing project into Pipeline because that would really help.

Is there a way how this can be done or do I have to write Jenkinsfile from scratch?

Not used it but you could try https://wiki.jenkins.io/display/JENKINS/Convert+To+Pipeline+Plugin — Chris Yallop, Feb 15 '18 at 10:38
agree, seems like a reasonable question to me. i wonder what guildine was violated. — Ray Tayek, May 01 '21 at 20:22
Not my close vote, but questions asking for software recommendations are explicitly off-topic here. This could perhaps be refactored into a "how can I" question but then the OP should contain at least a modicum of research effort. — tripleee, Jul 28 '21 at 08:05
I disagree, pipeline is something what you need to program also question popularity clearly shows people are interested so "purity of questions" vs reality of real world problems. — Zdenek Machek, Jul 29 '21 at 09:11

I don't know a tool that converts existing project to pipeline project, so I guess you'd have to start from scratch.

The documentation is not great but there are plenty of resource to follow:

Jenkins.io book pipeline section
Pipeline steps and workflow-basic-steps
fabric8 - great examples on how to use the Shared Groovy Library Plugin
http://your-jenkins/pipeline-syntax/ - Pipeline Snippet Generator and /pipeline-syntax/globals for global variable reference

@RMorrisey your-jenkins is meant as *your* jenkins host url address. The pipeline-syntax page is part of jenkins installation. – Tzafrir Mar 15 '18 at 18:38

I haven't tried it, but I've seen that others have. Use this to translate your current project's config.xml: https://github.com/visualphoenix/jenkins-xml-to-jobdsl

See https://stackoverflow.com/questions/8424228/export-import-jobs-in-jenkins for how to obtain the XML. – tripleee Jul 28 '21 at 08:37
