列出 git 个分支作为声明性管道中的动态参数

List git branches as dynamic parameter in declarative pipeline

我正在努力将动态选择参数包含到我的声明性管道中。我尝试了很多来自各地的不同建议,但这些建议并没有真正帮助,因为我现在完全迷失了方向:-)

对于所需的功能:我有一个用于 jenkins 管道的 Jenkinsfile(声明式)。我想要一个参数,它允许我从要在管道中使用的 git 存储库中选择一个特定的分支。

jenkinsfile 的基本结构:

pipeline {

    agent { node { label "XXX-XXX-XXX" } }

    options {
        gitLabConnection('XXX-XXX-XXX')
    }

    stages {
        stage("STAGE A") {
            parallel{
                stage("A"){
                    steps {
                        // DO STUFF
                    }
                }
                stage("B"){
                    steps {             
                        // DO STUFF
                    }
                }
            }
        }
    }
}

我尝试在管道中使用以下代码片段添加参数。我无法动态填充选择列表。它要么是空的,要么产生了错误。

parameters {
        choice(
            name: 'CHOICE_2',
            choices: 'choice_1\nchoice_2\nchoice_3\nchoice_4\nchoice_5\nchoice_6',
            description: 'CHOICE_2 description',
        )
}

或者,我尝试在管道声明之外添加以下内容。作为示例,我留下了一个脚本变体。同样,我无法填充选择列表。该字段留空:

node {
    label "XXX-XXX-XXX"
    properties([
        parameters([
            [$class: 'ChoiceParameter', 
                choiceType: 'PT_SINGLE_SELECT', 
                description: 'The names', 
                filterLength: 1, 
                filterable: true, 
                name: 'Name', 
                randomName: 'choice-parameter-5631314439613978', 
                script: [
                    $class: 'GroovyScript', 
                    script: [
                        classpath: [], 
                        sandbox: false, 
                        script: '''
                            def gettags = "git ls-remote git@XXX-XXX-XXX.git".execute()
                            def tagList = []
                            def t1 = []
                            String tagsString = null;
                            gettags.text.eachLine {tagList.add(it)}
                            for(i in tagList)
                                t1.add(i.split()[1].replaceAll('\^\{\}', ''))
                            t1 = t1.unique()
                            tagsString = StringUtils.join((String[])t1, ',');

                            return tagsString
                                '''
                    ]
                ]
            ], 
        ])
    ])
}

此时我尝试了太多不同的方法,想退后一步。

任何人都可以通过方法和一些提示或资源来支持我吗?

谢谢并致以最诚挚的问候,

我建议您构建一个包含远程分支列表的文件,之后您可以有一个阶段来批准并选择正确的分支 - 您是否尝试过多分支管道?也许它适用于您的用例...

pipeline {

    agent { node { label "XXX-XXX-XXX" } }

    options {
        gitLabConnection('XXX-XXX-XXX')
        skipDefaultCheckout() //this will avoid to checkout the code by defaul
    }

    stages {
        stage("Get Branches from Git Remote"){ // you might need to tweak the list retrieved from git branches cmd
            steps{
                 withCredentials([usernamePassword(credentialsId: 'git-credential', passwordVariable: 'key', usernameVariable: 'gitUser')]) {
