关键错误信息2： Could not transfer artifact com.＊:＊:pom:＊ from/to snapshots (http://dev-mvn.***.com/content/repositories/snapshots/)

关键错误信息3： Return code is: 401, ReasonPhrase: Unauthorized. -> [Help 1]

提取关键错误信息：Could not transfer …… from/to snapshots …… Return code is: 401, ReasonPhrase: Unauthorized.

很明显了，deploy的时候，权限不够大。于是排查maven setting配置文件，最终在……配置节点中增加如下配置，问题解决：

解决问题：

    snapshots
    deployment
    l****11

参考信息：

 
  
  
   
   snapshots
   
   my_login
   
   my_password
   
   ${usr.home}/.ssh/id_dsa
   
   some_passphrase
   
   664
   
   775
  
 

解决这个问题最关键要明白，下面配置的作用。
