Maven 使用技巧

  1. 多module,分stage 分开打包
    1. 目录结构 (a,b 依赖common)
      1. assembly
      2. commont
      3. a
      4. b
      5. pom.xml
    2. assembly/pom.xml 通过参数-Ddeploy.app=a 控制哪个模块

1. 编译a test 包:mvn clean package -am -pl assembly -Ddeploy.app=a -Ddeploy.stage=test
1. 编译b prod 包:mvn clean package -am -pl assembly -Ddeploy.app=b -Ddeploy.stage=prod
