参数未传递给jenkins parallel build

Question

我有一个管道作业，我试图使用Jenkins Groovy并行运行两个buildnode上的ansible playbooks。我只需要在prod期间执行第二个块。

stage ("Ansible Deploy") 
    {   
        parallel (
        'master' : {    
            stage ('Ansible Deploy on master server')
            {
                dir('ansible')
                {
                echo "$playbook"
                echo "$inventory"
                echo "$ansibleVersion"
                }
            }
        },
        'node2' : { 
            if(environment == 'prod') {
                node("$buildAgent2") 
                { 
                 stage ('Ansible Deploy on node2')
                    {
                    dir('ansible')
                    {
                    echo "$playbook"
                    echo "$inventory"
                    echo "$ansibleVersion"
                    }
                    }
                } 
                    } else  {
                            echo 'Skipping this block, as it only applicable for prod'
                            }
            }
       )
}

这是我在控制台上获得的输出，我没有看到在并行块中传递给node2的构建参数。

基于运行的输出
