- In Eclipse (go to Window > Preferences > General > Network connections).
- Select "Active Provider" as "Manual".
- Select HTTP and click edit.
- Enter the host and port
- Select "Requires Authentication" and enter the username and password.
Repeat Step 1 to 5 for Https.
In "proxy bypass" section click "Add host"
- Enter http://download.eclipse.org/releases/galileo/content.xmland OK
- 在 Eclipse 中（转到“窗口”>“首选项”>“常规”>“网络连接”）。
- 选择“Active Provider”作为“Manual”。
- 选择 HTTP 并单击编辑。
- 输入主机和端口
- 选择“需要身份验证”并输入用户名和密码。
对 Https 重复步骤 1 到 5。
在“代理绕过”部分点击“添加主机”
- 输入http://download.eclipse.org/releases/galileo/content.xml并确定
After spending an entire week with the issue, this solution finally worked for me

Maybe you're behind a firewall, and need to access the web through a proxy. Have you set a proxy in your web browser? If so, you need to set the same proxy in Eclipse (go to Preferences > General > Network connections).
也许您在防火墙后面，需要通过代理访问网络。您是否在网络浏览器中设置了代理？如果是这样，您需要在 Eclipse 中设置相同的代理（转到首选项 > 常规 > 网络连接）。

Well, try to enter this website: http://subclipse.tigris.org/update_1.6.x
好吧，尝试进入这个网站：http: //subclipse.tigris.org/update_1.6.x
If that link works, then it's not your fault. I've tried your link, and it doesn't work for me either.
如果该链接有效，那么这不是您的错。我试过你的链接，它对我也不起作用。
If the link I gave you doesn't work either, then the problem is on your side and you need to check your network settings.
如果我给您的链接也不起作用，那么问题出在您这边，您需要检查您的网络设置。

If you are behind a firewall, have set the proxy settings in the preferences correctly and it's still not working, Try setting -Dsun.net.client.defaultReadTimeout=<"amount in ms, e.g. 30000">in the eclipse.ini worked well for me. It looks like Eclipse has a quick timeout on that updatesite search. Some proxys can slow the process down by a few seconds and you get a timeout before the updatesite is loaded completely
如果您在防火墙后面，在首选项中正确设置了代理设置但它仍然不起作用，请尝试-Dsun.net.client.defaultReadTimeout=<"amount in ms, e.g. 30000">在 eclipse.ini 中进行设置对我来说效果很好。看起来 Eclipse 在该更新站点搜索上有一个快速超时。某些代理可能会使进程慢几秒钟，并且在更新站点完全加载之前您会超时
