篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了获取已推送更改的已更改分支的名称,Jenkins管道脚本相关的知识,希望对你有一定的参考价值。

我正在努力用我的项目设置我的CI / CD。我的SCM是gitlab,CI是jenkins。

我创建了一个非常好用的管道脚本。此外,我能够设置gitlab webhook,它可以在没有任何问题的情况下触发jenkins中的构建。

这是我的示例管道脚本:

    def running(gitlabBuildName) {
    updateGitlabCommitStatus(name: "${gitlabBuildName}", state: 'running')
}

def success(gitlabBuildName) {
    updateGitlabCommitStatus(name: "${gitlabBuildName}", state: 'success')
}

def failure(gitlabBuildName) {
    updateGitlabCommitStatus(name: "${gitlabBuildName}", state: 'failed')
}

properties ([
    [$class: 'GitLabConnectionProperty', gitLabConnection: 'gitlab'],
    pipelineTriggers([[
        $class: "GitLabPushTrigger",
        triggerOnPush: true,
        triggerOnMergeRequest: true,
        // triggerOpenMergeRequestOnPush:"both",
        //triggerOnNoteRequest: true,
        //noteRegex: "CI_STAGE_BUILD_THIS",
        // skipWorkInProgressMergeRequest: true,
        // ciSkip:false ,
        //setBuildDescription: true,
        //addNoteOnMergeRequest:true,
        addCiMessage: true,
        addVoteOnMergeRequest: true,
        acceptMergeRequestOnSuccess: true,
        branchFilterType: "NameBasedFilter",
        //targetBranchRegex: "some-branch",
        includeBranchesSpec: "master,stage,prod",
        excludeBranchesSpec: "dev"
    ]])
]);

pipeline {
    agent {
        label 'amazon-cloud'
    }
    options {
        gitLabConnection('gitlab')
        timeout(time:1, unit: 'HOURS')
    }
    environment {
        WORK_DIR = "${WORKSPACE}/${BUILD_NUMBER}"
    }
    stages {
        stage('PREDEPLOYMENT:: Cleanup the VM. '){
            steps{
                running("${JOB_NAME}")
                echo "Running for ${JOB_NAME}"
                echo "Deleting previous images. "
                dir("$WORKSPACE"){
                    sh 'rm -rf *'
                }
            }
            post{
                success {
                    echo "Success: VM cleaned up for further tests "
                }
                failure {
                    echo "Error: Some error occured while cleaning up the system"
                    failure("${JOB_NAME}")
                }
            }
        }
        stage('CHECKOUT: Checkout the 1st project Repos '){
            steps {
                checkout([$class: 'GitSCM', branches: [[name: "my-dev"]],
                doGenerateSubmoduleConfigurations: false,
                extensions: [[$class: 'RelativeTargetDirectory', relativeTargetDir: '$BUILD_NUMBER/my-node-1']],
                            submoduleCfg: [], userRemoteConfigs: [[credentialsId: "${GIT_SSH_KEY_ID}",
                            url: 'https://git_url/project_name1.git']]])

                checkout([$class: 'GitSCM', branches: [[name: "my-dev"]],
                doGenerateSubmoduleConfigurations: false,
                extensions: [[$class: 'RelativeTargetDirectory', relativeTargetDir: '$BUILD_NUMBER/my-node-2']],
                            submoduleCfg: [], userRemoteConfigs: [[credentialsId: "${GIT_SSH_KEY_ID}",
                            url: 'https://git_url/project_name2.git']]])



            }
            post {
                success {
                    echo "Success: Git checkout done for repos. "
                    echo "=========="
                    echo "${env.GIT_BRANCH}" // prints null
                }
                failure {
                    echo "Error: Some error occured while Git checkout of repos."
                    failure("${JOB_NAME}")
                }
            }
        }
        stage('CHECKOUT: Checkout the project2 Repos '){
            steps{
                checkout([$class: 'GitSCM', branches: [[name: "new-ui"]],
                doGenerateSubmoduleConfigurations: false,
                extensions: [[$class: 'RelativeTargetDirectory', relativeTargetDir: '$BUILD_NUMBER/project_name2']],
                            submoduleCfg: [], userRemoteConfigs: [[credentialsId: "${GIT_SSH_KEY_ID}",
                            url: 'https://git_url/project_name2.git']]])
            }
            post {
                success {
                    echo "Success: Git checkout done for project_name2 repos. "
                }
                failure {
                    echo "Error: Some error occured while Git checkout of project_name2 repos."
                    failure("${JOB_NAME}")
                }
            }
        }
        stage('BUILD: Temp: Prints env variables. ') {
            steps {
                echo "${BRANCH_NAME}"
            }
            post {
                success {
                    echo "Success: Successfully created the latest local build and tagged it."
                }
                failure {
                    echo "Error: Couldn't create the image. "
                    failure("${JOB_NAME}")
                }
            }
        }

        stage('Cleanup: Clean the VM Now. ') {
            steps {
                //sh 'docker rmi $(docker images -a -q) | echo "Not able to delete some images"'
                cleancleanWs()
            }
            post {
               success {
                   echo "Success: Cleaned up the vm. "
                   success("${JOB_NAME}")
                }
                failure {
                   echo "Error: Some error occured while cleaning up the vm. "
                   failure("${JOB_NAME}")
                    //cleanWs()
                }
            }
        }

    }
}

但上面代码的问题是我无法通过任何ENV变量找到分支名称。

对于exa。当更改被推送到分支时,我的jenskins作业会运行。但是我希望得到已经结帐的分支名称(推送更改的地方)并且依赖于此,我想在分支是“阶段”时运行一些额外的脚本。

我试图使用“env.BRANCH_NAME”等,但都显示为null。

任何人都可以帮助我,只需获得分支名称。

答案

env.BRANCH_NAME只能在multiBranchPipeline上工作,所以切换你的项目,你将获得分支名称:)
