1,由於預設外掛源在國外伺服器，大多數網路無法順利下載，需修改國內外掛源地址：
cd jenkins_home/updates
sed -i 's/http:\/\/updates.jenkins-ci.org\/download/https:\/\/mirrors.tuna.tsinghua.edu.cn\/jenkins/g' default.json && \
sed -i 's/http:\/\/www.google.com/https:\/\/www.baidu.com/g' default.json
然後重啟Jenkins：http://192.168.0.14:30006/restart

2,先安裝pipeline外掛。
pipeline {
   agent any

   stages {
      stage('1,拉取程式碼') {
		steps {
            echo "1"
        }
      }
	  stage('1,程式碼編譯') {
		steps {
            echo "2"
        }
      }
	  stage('1,單元測試') {
		steps {
            echo "3"
        }
      }
   }
}

拉取程式碼：

pipeline {
   agent any
   parameters {
		choice choices: ['192.168.0.11:/root/a.git', '192.168.0.11:/root/b.git', '192.168.0.11:/root/c.git'], description: '請選擇要釋出專案的git地址', name: 'git'
   
        choice choices: ['192.168.0.10', '192.168.0.11', '192.168.0.12'], description: '請選擇要釋出專案的伺服器', name: 'host'
   }

   stages {
      stage('1,拉取程式碼') {
		steps {
            echo "1"
        }
      }
	  stage('1,程式碼編譯') {
		steps {
            echo "2"
        }
      }
	  stage('1,單元測試') {
		steps {
            echo "3"
        }
      }
   }
}
