How to pass parameter to downstream job in Pipeline job?

Issue

I would like to pass a parameter value to a downstream job in a Pipeline job.

Environment

CloudBees Jenkins Enterprise
Pipeline

Resolution

Example:

Assume that I have a downstream freestyle job named downstream-freestyle, that contains two String parameters, named ParamA and ParamB.

In the upstream Pipeline job:

node {
    paramAValue = "paramAValue"
    paramBValue = "paramBValue"
    build job: 'downstream-freestyle', parameters: [[$class: 'StringParameterValue', name: 'ParamA', value: paramAValue], [$class: 'StringParameterValue', name: 'ParamB', value: paramBValue]]
}
