kind: pipeline
type: docker
name: default
steps:
  - name: build-package # 流水线名称
    image: maven:3.8-openjdk-8 # 定义创建容器的Docker镜像
    volumes: # 将容器内目录挂载到宿主机，仓库需要开启Trusted设置
      - name: maven-cache
        path: /root/.m2 # 将maven下载依赖的目录挂载出来，防止重复下载
      - name: maven-build
        path: /app/build # 将应用打包好的Jar和执行脚本挂载出来
    commands:
      - mvn -Dmaven.test.skip=true -P dev clean package
      - cp target/*.jar /app/build/*.jar
      
volumes: # 定义流水线挂载目录，用于共享数据
  - name: maven-build
    host:
      path: /data/app/maven/build # 从宿主机中挂载的目录
  - name: maven-cache
    host:
      path: /data/app/maven/cache

总结：用到 image: maven:3.8-openjdk-8镜像构建的，代码和编译后代码都在此容器中,所以要通过配置映射到宿主机中好操作！
