Groovy to call a Jenkins pipeline on another Jenkins instance

Question

There's a Jenkins pipeline in an instance , say A. I want to call another pipeline from Jenkins instance B in one of the stages in Jenkins instance A. How do I write a groovy for that? I had a look at this answer but it wasn't useful for me.

You can use jenkins plugin Parameterized Remote Trigger

It's easy to use.

You just need to configure jenkins instance B in manage jenkins. It uses jenkins api in backend.

For groovy help you can check http://${JENKINS_URL}/pipeline-syntax

Option 1: You can use HttpBuilder to trigger a remote build. Still you would need the Parameterized Build plugin.

import groovyx.net.http.HTTPBuilder
import static groovyx.net.http.ContentType.URLENC
 
def http = new HTTPBuilder( 'http://server/job/myjob/buildWithParameters' )
def postBody = [parameter: value] // will be url-encoded
 
http.post( path: '/', body: postBody,
           requestContentType: URLENC ) { resp ->
 
  println "POST Success: ${resp.statusLine}"
  assert resp.statusLine.statusCode == 201
}

Option 2: Or use cURL like described here: https://stackoverflow.com/a/42947382/519852

Anyway, in both cases it would only trigger the build and not wait for it to finish nor get its result.
