[FIXED] How to choose node label based on an expression?

Issue

I have this example pipeline

pipeline {
    parameters {
        string(name: 'PLATFORM', description: 'target platform to build to')
    }
    agent {
        node {
            /* I want to choose 'windows-machine' 
               when PLATFORM matches "windows.*" */
            label 'linux-machine'
        }
    }
}

I want jobs that target windows platforms to run on different nodes. How can you choose node labels based on whether pipeline parameters match an expression or not?

Solution

Instead of node, you can use agent selector label. Here is an example of how you can do this.

pipeline {
    parameters {
        string(name: 'PLATFORM', description: 'target platform to build to')
    }
    agent {label PLATFORM=='WINDOWS' ? 'windows': 'linux'}
    stages {
        stage('Test') {
            steps {
                script {
                    echo "test"
            }
        }
    }
}
}
