解决Jenkins上git时出现“ERROR: Timeout after 10 minutes”的时间超时问题

环境：使用jenkins通过pipeline拉取github代码

最近在Jenkins上新建Job时，使用Pipeline流水线方式自动化发布项目报错具体如下：

ERROR: Timeout after 10 minutes”

分析原因：

1.Github属于国外网站，经常访问不稳定，一般需要梯子

2.代码仓库文件过大，请求超时

解决方式：

在pepeline脚本中的extensions（扩展插件）中添加设置timeout时间为30min，默认为10min，即可解决


   stages {
        stage('拉取源码') {
            steps {
                checkout([
                    //详情看https://www.cnblogs.com/liucx/
                    $class: 'GitSCM', branches: [[name: "${branch}"]],
                    doGenerateSubmoduleConfigurations: false,extensions: [[$class:'CheckoutOption',timeout:30],[$class:'CloneOption',depth:0,noTags:false,reference:'',shallow:false,timeout:30]], submoduleCfg: [],
                    userRemoteConfigs: [[credentialsId: 'github', url: "${project_url}"]]
                ])
            }
        }
