How can you pass same parameters to different builds without redundant code in Jenkins Pipeline

问题

How can you pass same parameters to different builds without redundant code in Jenkins Pipeline groovy. I don't want to repeat the parameters.

node('master') {
    parallel(
        "stream 1(X)" : {
        stage('X') {
            build 'Job1', parameters: [string(name: 'branch', value: 'trunk'), string(name: 'freq', value: 'Continuous')]
        }
        },
        "stream 2 (Y)" : {
            stage('Y') {
                build 'Job2', parameters: [string(name: 'branch', value: 'trunk'), string(name: 'freq', value: 'Continuous')]
            }
        }
    )
}

It is pretty easy : just add a function, say buildJob, that will take your job name as a parameter and then set all jobs parameters as you do it now :

node('master') {
    parallel(
        "stream 1(X)" : {
        stage('X') {
            buildJob("Job1")
        }
        },
        "stream 2 (Y)" : {
            stage('Y') {
                buildJob("Job2")
            }
        }
    )
}

def buildJob(jobName) {
    build name: jobName, parameters: [string(name: 'branch', value: 'trunk'), string(name: 'freq', value: 'Continuous')]
}
