Maven常见问题

1、关于Pom基础的group问题

         问题描述：

                   新建了一个多模块项目，父模块继承自spring-boot-starter-parent，父模块中未指定group.id，导致在子模块一直报找不到父模块的错误。

         解决方案：

                   在父模块中加入group.id配置。

         问题原因分析：

                   如果模块中不指定group.id属性，默认模块继承其父模块的group.id属性。像此种情况，我新建的父pom和springboot的group不属于同一group，但在子模块中指定了不同于springboot的group.id，导致报不能解析父模块的pom。

 

2、Maven的顶级POM
