jenkins - 如何使用 Jenkins 管道脚本克隆 github 存储库？

Question

我对 CI/CD 概念比较陌生。

我正在尝试使用 Jenkins 中的声明性管道(没有 SCM)克隆 Github 存储库。

如果我在没有任何凭据的情况下执行此操作，那么我可以在控制台输出中看到 Jenkins 已经在尝试克隆该存储库，但需要很长时间。我已经可以看到，在 Jenkins 工作区中，我有一个名为我的 github 存储库的文件夹，但它只有一个 .git文件夹里面，它需要永远但永远不会拉 repo 。在互联网上搜索后，我发现缺少访问存储库的权限。

然后我在 Jenkins 中添加了我的 Github 存储库的凭据。我有以下脚本。

pipeline {
   agent any
   stages {
      stage('clone repo') {
          steps {
              withCredentials(usernamePassword(credentialsId :jenkins-user-github ,passwordVariable: 'GIT_PASSWORD', usernameVariable: 'GIT_USERNAME' )){
              // Get some code from a GitHub repository
              bat("""
              git config --global credential.username {GIT_USERNAME}
              git config --global credential.helper "!echo password={GIT_PASSWORD}; echo"
              git clone https://github.com/aakashsehgal/FMU.git

              echo "pulled the code"
              """)

          }


         }

         }
      }

}

但我收到以下错误:

知道我在这里缺少什么吗？

Answer 1

您在阶段中使用用户名和密码时出现语法错误。你应该像 ${GIT_USERNAME}而不是 {GIT_USERNAME}独自的。

话虽如此，您需要明确提及您需要 check out 哪个分支。

我假设您希望默认情况下结帐到 master 分支。所以使用下面的:

pipeline {
   agent any
   stages {
    stage('Checkout') {
      steps {
        script {
           // The below will clone your repo and will be checked out to master branch by default.
           git credentialsId: 'jenkins-user-github', url: 'https://github.com/aakashsehgal/FMU.git'
           // Do a ls -lart to view all the files are cloned. It will be clonned. This is just for you to be sure about it.
           sh "ls -lart ./*" 
           // List all branches in your repo. 
           sh "git branch -a"
           // Checkout to a specific branch in your repo.
           sh "git checkout branchname"
          }
       }
    }
  }
}

如果您想在默认情况下结帐到特定分支，请在您的管道阶段使用以下内容。使用以下部分，您将不需要运行 git checkout分别指挥。

pipeline {
   agent any
   stages {
        stage('Checkout') {
            steps {
                checkout([$class: 'GitSCM', branches: [[name: '*/branchname']], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: 'jenkins-user-github', url: 'https://github.com/aakashsehgal/FMU.git']]])
                sh "ls -lart ./*"
            }
        }     
    }
}
