今天deploy一个jar包到私服上时，一直报错，原因一大串：

Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.7:deploy (default-deploy) on project ussp-common-parent: Failed to deploy artifacts: Could not transfer artifact com.ussp.common:ussp-common-parent:pom:1.0.0-20190214.060901-540 from/to snapshots (http://192.168.1.45:8081/nexus/content/repositories/snapshots/): Failed to transfer file: http://192.168.1.45:8081/nexus/content/repositories/snapshots/com/ussp/common/ussp-common-parent/1.0.0-SNAPSHOT/ussp-common-parent-1.0.0-20190214.060901-540.pom. Return code is: 401, ReasonPhrase: Unauthorized. -> [Help 1][ERROR]

可以看到最后显示，返回码是401，跟授权或权限相关。可是我的settings.xml文件里面的用户权限足够，怎么还报权限不足呢？我找了一大圈，终于发现是pom.xml文件与settings.xml关于授权相关的配置没对应起来导致的，下面是我pom中的配置：

    		
     			
      
       releases
      			
      
       Nexus Release Repository
      			
      
       http://192.168.1.X:8081/nexus/content/repositories/releases/
      		
     		
     			
      
       snapshots
      			
      
       Nexus Snapshot Repository
      			
      
       http://192.168.1.X:8081/nexus/content/repositories/snapshots/
      		
     
    

下面是我settings.xml的配置:

    	
     
      nexus-releases
     	
     
      admin
     	
     
      admin
     	
    	
    	
     
      nexus-snapshots
     	
     
      admin
     	
     
      admin
     
    

比较可以看到 pom中repository和snapshotRepository两个库的id没有与settings.xml中对应起来。修改一致即可发布成功。
