Hi guys, Can you give an example to pass parameters from one job to another job? (Pipeline project)
I have been stuck with this for a while now, kindly provide suggestions.

I'm trying the below, which did not work for me:(

Project Name: test2
node() {
stage 'pass params'
paramAValue = "paramAValue"
paramBValue = "paramBValue"
build job: 'test3', parameters: [[$class: 'StringParameterValue', name: 'ParamA', value: paramAValue], [$class: 'StringParameterValue', name: 'ParamB', value: paramBValue]]
}

Project Name: test3
node() {
stage 'retrieve params'
print "${env.paramA}"
}

stage ('pass params') {
def paramAValue = "paramAValue"
...
}

etc.

Also try:
echo paramA not print "${env.paramA}"

The preferred method of getting job parameters is to use the "params" map.

So use echo params.paramA

See https://jenkins.io/doc/book/pipeline/syntax/#parameters

Can someone please give an example of jenkins file which shows how to connect to jenkins slave and execute the shell scripts and python scripts residing in jenkins slave itself.
