2. Add node properties environment variables, name: Path value: $Path;X;Y;Z
3. Run pipeline job that displays the path

pipeline {
    agent {
        label 'slave-1'
    }
    stages {
        stage('path') {
            steps {
                bat('path')
            }
        } //stage
    } //stages
} //pipeline
