Jenkins Pipeline

可以在pipeline工程中打開Pipeline Syntax
在代碼倉庫創建Jenkinsfile文件

pipeline {
    agent any
    stages {
        stage('ready') {
              steps {
                    sh 'echo "ready to build"'
              }
        }
        stage('Build') {
              steps {
                    echo "Building"
                    sh '''mvn clean install'''
              }
        }
        stage('Test') {
              steps {
                   echo "Testing"
              }
        }
        stage('Deploy') {
              steps {
                   echo "Deploying"'
                   archiveArtifacts artifacts: '**/target/*. jar', fingerprint: true, onlyIfSuccessful: true
                   sh '''cp ${WORKSPACE}/${buildPath}/target/*. jar ${uploadPath}
              }
        }
        stage('Clean') {
              steps {
                   echo "Cleaning"
              }
        }
    }
    post {
        succese {
            echo 'success build!'
            sh '''for((i=1;i<=`expr ${BUILD_NUMBER} - 5`;i++));
            do
            archivePath="${JENKINS_HOME}/jobs/${JOB_NAME}/builds/$i/archive/"
            if [ -d $archivePath ]; then
            echo "$archivePath文件夾已經存在"
            rm -rf $archivePath
            fi
            done'''
        }
    }
}

sh命令多行時需要三個單引號'

常用Step

echo, 打印消息。echo 'hello'
build, 構建其他jenkins job。build 'api-job'
sh, 執行linux腳本。
bat, 執行windows腳本。
archiveArtifacts artifacts, 歸檔打包好的文件archiveArtifacts artifacts: '**/target/*. jar'
fileExists, 判斷文件是否存在。fileExists 'mypath'
dir, 改變構建文件夾。

dir (mypath) {
      sh '''mvn clean install'''
}

常用的環境變量

${WORKSPACE} #構建工作區
${GIT_COMMIT} #git代碼構建時commit SHA1值
${JOB_NAME} #構建…工程名稱
