Eclipse 更新不起作用
我已经在 64 位 Windows 平台上安装了 Eclipse 3,6。 当我尝试通过帮助->安装新软件连接到更新站点时，它会出现以下错误：
Unable to connect to repository
http://download.eclipse.org/releases/galileo/content.xml
Connection refused: connect
我已尝试了所有可用的站点 - 它们都给了我相同的错误。 对话框显示：配置异常。
知道发生了什么吗？
I have installed Eclipse 3,6 on 64 bit Windows platform.
When I try to connect to update sites by going to Help->install new software it gives following error:
Unable to connect to repository
http://download.eclipse.org/releases/galileo/content.xml
Connection refused: connect
I have tried all available sites - they all give me the same error.
Dialog box shows: Provision exception.
Any idea what's happening?

对于 Https，重复步骤 1 到 5。
在“代理绕过”部分中单击“添加主机”
在花了整整一周的时间解决这个问题后，这个解决方案终于对我有用了
Repeat Step 1 to 5 for Https.
In "proxy bypass" section click "Add host"
After spending an entire week with the issue, this solution finally worked for me
也许您位于防火墙后面，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”）。
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).
好吧，尝试进入这个网站： http://subclipse.tigris.org/update_1.6.x
如果该链接有效，那么这不是您的错。我已经尝试过你的链接，但它对我来说也不起作用。
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。
Well, try to enter this website: 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.
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.
如果您位于防火墙后面，已在首选项中正确设置了代理设置，但仍然无法正常工作，请尝试设置
-Dsun.net.client.defaultReadTimeout=<“以毫秒为单位的金额，例如 30000”> 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减慢几秒钟，并且在更新站点完全加载之前您会遇到超时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
