我刚刚在一个公司代理后面安装了Nexus 2.2-01。当我直接进入中央回购协议时，Maven正在工作，但当我配置

通过Nexus web UI，我可以：

• 中环的“浏览远程”
• “浏览索引”
• 从“工件信息”选项卡上，我可以下载JAR（非本地缓存）
• 然后去看电影。罐子和瓶子。罐子sha1文件位于“http://127.0.0.1:8081/nexus/content/groups/public/以及“\nexus\sonatype work\nexus\storage\central”

...但是由于某些原因，它没有下载。pom文件

Nexus 2.2附带了一个用于中央预配置的代理存储库，我可以从web UI手动浏览索引和下载文件——那么为什么它不能在Maven上运行呢？

我已将Nexus配置为具有身份验证的默认HTTP代理设置，但仍会出现以下错误：
