How to pass output from one pipeline to another in jenkins

I'm new to Jenkins and I've been tasked with a simple task of passing the output from one pipeline to the other.

Lets say that the first pipeline has a script that says echo HelloWorld, how would i pass this output to another pipeline so it displays the same thing.

I've looked at parameterized triggers and couple of other answers but I was hoping if someone could layout the step by step procedure to me.

If you want to implement it purely with Jenkins pipeline code - what I do is have an orchestrator pipeline job that builds all the pipeline jobs in my process, waits for them to complete then gets the build number:

Orchestrator job

def result = build job: 'jobA'
def buildNumber = result.getNumber()
echo "jobA build number : ${buildNumber}"

In each job like say 'jobA' I arrange to write the output to a known file (a properties file for example) which is then archived:

jobA

writeFile encoding: 'utf-8', file: 'results.properties', text: 'a=123\r\nb=foo'

archiveArtifacts 'results.properties'

Then after the build of each job like jobA, use the build number and use the Copy Artifacts plugin to get the file back into your orchestrator job and process it however you want:

Orchestrator job

    step([$class     : 'CopyArtifact',
          filter     : 'results.properties',
          flatten    : true,
          projectName: 'jobA',
          selector   : [$class     : 'SpecificBuildSelector',
                        buildNumber: buildNumber.toString()]])

You will find these plugins useful to look at:

If you are chaining jobs instead of using an orchestrator - say jobA builds jobB builds jobC etc - then you can use a similar method. CopyArtifacts can copy from the upstream job or you can pass parameters with the build number and name of the upstream job. I chose to use an orchestrator job after changing from chained jobs because I need some jobs to be built in parallel.
