聚合类工程又一个个的子模块组成
pom文件也是由一个基础root pom文件 一层一层的依赖集成的关系组成
项目结构:
工程结构
videos -dev工程是root工程,也就是根节点,其他项目工程的pom依赖这上一个节点。
依赖关系是videos-dev <-videos-dev-common<- videos-dev-pojo<-videos-dev-mapper<-videos-dev-service<-videos-dev-api
1.项目搭建过程
新建一个空的maven项目
2.然后新建model,添加依赖
创建第一个子结构工程

maven project里 在根目录的maven里 install的时候报错解决方案:
1.在其他根节点的pom.xml里添加 <relativePath>../videos-dev-service/pom.xml</relativePath>
2.再添加<packaging>pom</packaging>
3.添加依赖:
1.<parent>
<relativePath>../videos-dev-service/pom.xml</relativePath>
</parent>
2.<packaging>pom</packaging>
3. <dependencies>
