下次我尝试再次下载时，出现错误:

No repository found at http://download.jboss.org/jbosstools/updates/stable/kepler/.

我的互联网连接没有问题，但我不确定为什么在安装软件 JBoss Tools 时会出现此类错误。
请提出任何解决方案。

Answer 1

我刚刚遇到了同样的问题，而且我使用的是直接连接。检查网络连接，我注意到它被设置为“ native ”(可能是 Eclipse Kepler 的默认设置，因为我的安装是相当新的)。

通过将网络连接“Active Provider”从Native 更改为Direct 解决了这个问题。

Eclipse 中的网络配置路径: Windows>>首选项>>常规>>网络连接
