jenkins - 如何在声明性 Jenkins 文件内的 Jenkins 多管道中设置响应式(Reactive)选择参数

Question

当我为扩展选择参数选择值时，我需要一个响应式(Reactive)选择参数来为我提供 1-3 个选项。

以下代码给我错误:

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed: WorkflowScript: 4: Build parameters cannot be defined as maps @ line 4, column 9. [$class: 'CascadeChoiceParameter', ^

1 error

pipeline {
    parameters {
        extendedChoice(defaultValue: 'none', description: 'Select the resource you want to modify', multiSelectDelimiter: ',', name: 'Resources', quoteValue: false, saveJSONParameterToFile: false, type: 'PT_SINGLE_SELECT', value: 'Compute, LIVE', visibleItemCount: 2) 
        [$class: 'CascadeChoiceParameter', 
        choiceType: 'PT_SINGLE_SELECT',
        description: 'Select a choice',
        filterLength: 1,
        filterable: true,
        name: 'choice1',
        referencedParameters: 'Resources',
        script: [$class: 'GroovyScript',
            fallbackScript: [
                classpath: [], 
                sandbox: true, 
                script: 'return ["ERROR"]'
            ],
            script: [
                classpath: [], 
                sandbox: true, 
                script: """
                    if (Resources == 'Compute') { 
                        return['aaa','bbb']
                    }
                    else {
                        return['ccc', 'ddd']
                    }
                """.stripIndent()
            ]
        ]
    ]

如何在声明性管道中实现这一目标？

谢谢

您可以使用以下代码来满足您的要求。

 properties([
    parameters([
        
        extendedChoice(defaultValue: 'none', description: 'Select the resource you want to modify', multiSelectDelimiter: ',', name: 'Resources', quoteValue: false, saveJSONParameterToFile: false, type: 'PT_SINGLE_SELECT', value: 'Compute, LIVE', visibleItemCount: 2),
        [$class: 'CascadeChoiceParameter', 
        choiceType: 'PT_SINGLE_SELECT',
        description: 'Select a choice',
        name: 'choice1',
        referencedParameters: 'Resources',
        script: [$class: 'GroovyScript',
            fallbackScript: [
                classpath: [], 
                sandbox: true, 
                script: 'return ["ERROR"]'
            ],
            script: [classpath: [], sandbox: false, script: '''
            def getChoice1(){
                def value = ""
                    switch(Resources) {
                        case "Compute":
                            value = ["aaa", "bbb"]
                            break
                        case "LIVE":
                            value = ["ccc", "ddd"]
                            break
                    }
            }
            def choice1 = getChoice1()
            return choice1
            '''
            ]
        ]
    ]
    ])
])

pipeline {
agent any
// do anything inside pipeline
}
