maven聚合与继承
   聚合：一条命令构建多个模块
   <project>
       <modelVersion>4.0.0</modelVersion>

       <groupId>com.jubenxu.mvnbook.account</groupId>
       <artifactId>account-aggregator</artifactId>
       <version>0.0.1-SNAPSHOT</version>
       
       <packaging>pom</packaging>
       <name>Account Aggregator</name>
       <modules>
           
           <module>../account-email</module>
           <module>../account-persist</module>
           
           <module>../account-parent</module>
       </modules>

   </project>
   <packaging>元素的值为pom,<module>元素指定要聚合模块的POM文件目录。

   继承：简化配置
   父模块
   <project>
       <modelVersion>4.0.0</modelVersion>
