I am running a pipeline job and with this we need to pass a parameter to a downsteam job but its not working. We tried as follows:

Pipeline JOB:

node 
 parameters 
 choice(
 name: 'OS',
 choices:"WindowsnLinuxnMAC",
 description: "Choose Environment to build!")
 
 stage('Build') 
 if("$params.Environment" == 'Windows')
 
 paramAValue = "$params.Environment"
 build job: 'QA-Test-Windows',parameters: [[$class: 'StringParameterValue', name: 'ParamA', value: "$paramAValue"]]
 
 
 

QA-Test-Windows is a Freestyle job and in that we tried accessing the parameter in script as follows but its not working.

Write-output "OS selected for testing is $params.ParamA"

Write-output "OS selected for testing is $ParamA"

Tried accessing variables but its not working. Can anyone please help me on this. We tried creating QA-Test-Windows freestyle job as Pipelinejob but in this freestyle there are lot of Build steps.

I'm not sure what exactly wrong in your code, looks like there is mistake. Maybe you need to wrap your "$paramAValue" into too. when you tries to run downstream job?

But, according to what you want, I just tested this working solution:

I have two pipeline jobs (upstream and downstream):

• Downstream job has parameter with name OS




• Upstream job has choice parameter PickAnOS

and there is working pipeline script for upstream job, which runs downstream job with the selected parameter

pipeline 
 agent any
 parameters 
 choice(choices: ['Windows', 'Linux'], description: 'What OS?', name: 'PickAnOS')
 
 stages 
 stage("run downstream job") 
 steps 
 echo "You choose: $params.PickAnOS"
 build job: 'downstream_job', parameters: [string(name: 'OS', value: '$params.PickAnOS')]
 
 
 

I hope this helps

ON THE CALLING JOB:

pipeline 
 agent any

 parameters 
 string(defaultValue: "123", description: 'This is a parameter', name: 'PARAMETER01')
 

 stages 
 stage('Start')
 steps
 build job: 'ANOTHER_JOB_NAME', wait: false, parameters: [string(name: 'HELLO', value: String.valueOf(PARAMETER01))]
 
 
 

ON THE SECOND JOB:

pipeline 
 agent any

 parameters 
 string(defaultValue: "", description: 'K', name: 'HELLO')
 

 stages 
 stage('PrintParameter')
 steps
 sh 'echo $HELLO'
