我刚刚安装的Nexus 2.2-01后面的企业代理。 Maven的工作时，我直接到中央回购，但是当我配置<mirror>在%M2_HOME%\conf\settings.xml ，我不能做一个简单的mvn archetype:create或mvn clean 。
从Nexus的网络界面，我可以：
- 在中央“浏览远程”。
- “浏览目录”
- 和它说：“（不本地缓存）”中的“神器信息”选项卡，我可以下载的罐子
- 再看看在“http://127.0.0.1:8081/nexus/content/groups/public/”和“\关系\ Sonatype的工作\关系\存储\中央” .jar和.jar.sha1文件
...但由于某些原因，它不下载.pom文件
2.2的Nexus带着中央预配置的代理库，我可以浏览索引并从Web UI手动下载文件 - 那么，为什么不会从Maven的工作吗？
我已经配置了与身份验证默认HTTP代理服务器设置的Nexus，但仍然得到错误，如：
