Jenkins通过Pipeline流水线方式编译Java项目

记录一下本人流水线配置，前提使用的jenkins:lts镜像然后自己通过dockerfile添加了JDK1.8和mvn插件，因为Jenkins镜像中的java版本过高编译我的项目会有问题所以新加一个1.8的。

docker-compose启动Jenkins

services:
  jenkins:
    image: jenkins-mvn:lts  
    container_name: jenkins
    restart: on-failure:3
    user: root

    network_mode: host

    environment:
      TZ: Asia/Shanghai
      LANG: zh_CN.UTF-8
      LANGUAGE: zh_CN:zh
      LC_ALL: zh_CN.UTF-8

    volumes:
      - /data/jenkins/jenkins-data:/var/jenkins_home   # Jenkins数据目录持久化
      - /usr/bin/docker:/usr/bin/docker   # 宿主机docker命令
      - /var/run/docker.sock:/var/run/docker.sock  # docker.sock用于执行宿主机容器命令
      - /etc/localtime:/etc/localtime:ro           # 时区同步
      - ./settings.xml:/opt/maven/conf/settings.xml  #私服配置

启动之后安装Jenkins推荐插件，然后再一下插件
