我在Linux虚拟机上安装了Nexus 2.8。启动它，可以很愉快地浏览到存储库。如果我从存储库视图中查看存储库，它们都在服务中，并且没有一个被阻止。
我可以浏览单个repo索引，但有一件事我担心的是，当我更新或重建索引时，我得到以下内容，其中显示0扫描，更新读取等。

我的公共存储库已配置，以便所有存储库都位于可用的存储库框中。我不认为我需要为此做任何其他配置，因为我还没有开始玩它只是想让默认设置先工作。我已经为每个repo设置了下载远程索引为true。
当我尝试通过eclipse创建maven项目时，我无法创建它。我在控制台中收到以下错误

我可以浏览遥控器并看到这些罐子存在，所以为什么我不能在我的eclipse IDE中下载它们？

我已经设置了代理配置，因为我在防火墙后面并且确认它有访问权限，因为没有抛出任何错误并且可以运行运行状况检查，尽管它返回0但不会抛出任何错误。
任何人都知道为什么这不起作用？
此外，如果我把它放在网址
我得到以下输出

答案 0 :(得分：2)
您的公共存储库组必须将左侧列中的所有存储库标记为“Ordered Group Repositories”，而不是在可用的存储库列表中。在http://books.sonatype.com/nexus-book/reference/config-sect-repo-group.html和http://books.sonatype.com/nexus-book/reference/confignx-sect-managing-groups.html
中查看有关该详细信息此外，您应通过使用存储库配置中的“浏览远程”选项卡确认您可以通过代理配置访问远程存储库（以Central开头）。
检查完所有内容并修复后，我会删除本地Maven存储库（〜/ .m2 / repository）并尝试命令行构建。一旦有效......将Eclipse与M2e一起使用..
