It helps to create aggregators and parent projects.An aggregator or multi-module project assembles submodules coming from different sources. These submodules are regular Maven projects and follow their own build lifecycles. The aggregator POM has all the references of submodules under the modules element.管理继承和集成A parent project allows you to define the inheritance relationship between POMs. The parent POMshares certainconfigurations, plugins, and dependencies, along with their versions. Most elements from the parent are inherited by its children — exceptions include artifactId, name, and prerequisites.子模块之间依赖传递对父级项目执行maven命令时会对所有的子模块执行相同的命令。定义pom之间的继承关系统一管理依赖和一些插件
