pipeline参数化

parameters是参数的意思，parameters指令提供用户在触发Pipeline时应提供的参数列表。这些用户指定的参数的值通过该params对象可用于Pipeline步骤。

生成流水线

1. 字符串参数
   就是定义一个字符串参数，用户可以在Jenkins UI上输入字符串，常见使用这个参数的场景有，用户名，收件人邮箱，文件网络路径，主机名称的或者url等

parameters {
  string defaultValue: 'fea/v1.0.1', description: 'please give a name', name: 'branch', trim: false
}

2.选择参数
选择（choice）的参数就是支持用户从多个选择项中，选择一个值用来表示这个变量的值。工作中常用的场景，有选择服务器类型，选择版本号等。

parameters {
  choice choices: ['1.1', '1.2', '1.3'], description: 'select the version to test', name: 'version'
}

pipeline脚本

pipeline {
   agent any
options{  timestamps () }
environment {
parameters {
  string defaultValue: 'feature/v1.0.1', description: '请输入需要发布的分支', name: 'branch', trim: false
  choice choices: ['1.1', '1.2', '1.3'], description: 'select the version to test', name: 'version'
}
   stages {
      stage('get code ') {
         steps {
          sh("ls -al ${env.WORKSPACE}")
          deleteDir()  
          sh("ls -al ${env.WORKSPACE}")
          checkout([$class: 'GitSCM', branches: [[name: '*/master']], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[url: '[email protected]:front/dfc.git']]])   
	 
         }
      }

stage ('get branch-test'){
 steps {
      sh '''
echo $version
git checkout $branch
git pull origin $branch
echo "-------------"
/usr/local/bin/cnpm install
npm run build:test
'''
            }
          }

        }

    }
     

最后运行按键也变了
