  依賴管理dependencyManagement
   假設不使用依賴管理。子pom會繼承父pom中配置的所有依賴，子pom中僅僅需配置本身特需的依賴便可了，
   這樣儘管簡化了子pom的配置。但是強制性給子pom加上多餘的依賴。
   
   使用依賴管理，子pom中要配置本身需要的依賴。假設這些依賴在父pom中配置了，
   子pom僅僅需指定這些依賴的groupId和artifactId
   
   
  依賴管理的導入
   將proj-A中的依賴管理導入此pom的依賴管理中
   
   <scope>import</scope>僅僅用在依賴管理配置中。且<type>pom</type>
