下次我再次尝试下载时出现错误：

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

我的互联网连接没有问题，但我不确定为什么安装软件JBoss Tools时会出现这样的错误。
请建议任何解决方案。

Answer 1

我刚遇到同样的问题，而且我正在使用直接连接。 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，因为我的安装相当新）。

它是通过将网络连接“活动提供程序”从Native更改为Direct来解决的 。

Eclipse中网络配置的路径： Windows >>首选项>>常规>>网络连接

Answer 2

Eclipse Luna也出现同样的问题。 将Active Provider设置为Direct可以解决问题。

Answer 3

对我来说，上述答案不起作用，因为我们使用代理连接到互联网。 所以我们的设置是手动的网络

但我解决了它：

1. 转到Help - > Install New Software 。
2. 添加存储库链接http://download.jboss.org/jbosstools/updates/stable/kepler 。
3. 从选项中选择Hibernate Tools 。
4. 接受许可并继续安装。
5. 重启Eclipse和Hurray！
