java.lang.IllegalArgumentException：并行执行阶段时需要指定的命名参数

Question

我有一个管道，我想在其中并行运行阶段（这是动态的，因此我有以下代码-

pipeline {
        agent any

        stages {
            stage("Dynamic stages") {
                steps {
                    script {
                        def tests = params.VMs.split(',')
                        for (int i = 0; i < tests.length; i++) {
                            parallel {
                                stage("Test ${tests[i]}") {
                                    steps {
                                        echo "Executing stage ${tests[i]}"
                                    }
                                }
                            }
                        }
                    }
                }
            }
        }
    }

但它导致以下错误-

有人可以帮我解决这个问题吗？

[parallel需要一张地图：

                        def tests = params.VMs.split(',')
                        def builders = [:]
                        for (test in tests) {
                            builders[test] = {
                                stage("Test ${test}") {
                                    steps {
                                        echo "Executing stage ${test}"
                                    }
                                }
                            }
                        }
                        parallel builders
