Customizing parameters

Declarative Pipeline supports parameters out-of-the-box, allowing the Pipeline to accept user-specified parameters at runtime via the parameters directive. Configuring parameters with Scripted Pipeline is done with the properties step, which can be found in the Snippet Generator.

If you configured your pipeline to accept parameters using the Build with Parameters option, those parameters are accessible as members of the params variable.

Assuming that a String parameter named "Greeting" has been configuring in the Jenkinsfile, it can access that parameter via ${params.Greeting}:

// Declarative //
pipeline {
    agent any
    parameters {
        string(name: 'Greeting', defaultValue: 'Hello', description: 'How should I greet the world?')
    }
    stages {
        stage('Example') {
            steps {
                echo "${params.Greeting} World!"
            }
        }
    }
}
// Script //
properties([parameters([string(defaultValue: 'Hello', description: 'How should I greet the world?', name: 'Greeting')])])

node {
    echo "${params.Greeting} World!"
}
