关于连接的 Nexus Os 错误
Nexus Oss error regarding connection
我是新的 nexus oss ( 3.2.0) 安装和访问 nexus 后，我可以在日志中看到一些错误，看起来 nexus 和外界之间存在连接问题。
日志如下

有没有什么办法可以为 nexus 提供代理设置？有人可以指导我吗
我可以看到某些组件的状态显示为在线远程连接挂起。
信息性日志消息是因为您的计算机未与外界连接。这不是警告或错误，不会影响您的表现。
您看到的屏幕截图字符串是因为 NXRM3 系统中的混淆消息（以及与 NXRM2 的偏差）以及 NXRM3 当前未设计为在调用之前联系远程代理这一事实。此处描述了这种偏差：https://issues.sonatype.org/browse/NEXUS-9878
这些存储库实际上已准备好连接。如果它们失败了（例如，如果您尝试使用它们而您的计算机未连接到外界），则会出现这样的消息。一旦您与他们建立联系（例如从他们那里接收组件），他们将变为 "Online - Remote Available".
在 NXRM3 的下一个版本中，消息将从 "Online - Remote Connection Pending..." 更改为 "Online - Ready to Connect" 以帮助缓解这种混乱。 Public 票在这里：https://issues.sonatype.org/browse/NEXUS-11001
在系统 ----> HTTP 下有一个为出站连接添加代理的选项。
这样效果很好。
