## Maven坐标的概念 ##

给每个jar包定义一个坐标，我们在项目中通过这个坐标来引用需要的jar包。坐标的作用用于唯一标识每个jar包。

## dependencyManagement ##

<dependencyManagement> 
    
         
            <dependencies> 
                <dependency> 
                </dependency> 
            </dependencies> 
        </dependencyManagement>

通过以上三层结构就可以在仓库里面定位到一个jar包，坐标的每个组成部分都对应仓库里面的一级目录结构。如果之前已经访问过，则在本地仓库中也可以找到。

有一些groupId项目名字对应两级目录，而artifactId和version元素都对应一级目录
