如何更改 Eclipse 更新管理器的“读取超时”值？
I have slow internet connection and I cannot install any plugin, because Eclipse's Update manager throws me exception:
我的互联网连接速度很慢，我无法安装任何插件，因为 Eclipse 的更新管理器向我抛出异常：

As Frank mentioned you can set the timeout options in the eclipse.ini, here's the documentation.
正如 Frank 提到的，您可以在 eclipse.ini 中设置超时选项，这是文档。
"use -DpropName=propValue as a VM argument to the Java VM, set the desired property in the config.ini file in the appropriate configuration area"
“使用 -DpropName=propValue 作为 Java VM 的 VM 参数，在相应配置区域的 config.ini 文件中设置所需的属性”
I set the following to get round my timeout issue:
我设置了以下内容来解决我的超时问题：
-Dorg.eclipse.ecf.provider.filetransfer.retrieve.closeTimeout=3000
-Dorg.eclipse.ecf.provider.filetransfer.retrieve.readTimeout=3000

I got the error a lot with version 3.6, but adding the following line to the eclipse.ini helped me a lot:
我在 3.6 版中遇到了很多错误，但是在 eclipse.ini 中添加以下行对我有很大帮助：
-Dsun.net.client.defaultReadTimeout=30000
Add it right after the line with -vmargs
在带有 -vmargs 的行之后添加它

The easiest way to get around this would be to download the .jarfile of the plug-in you're trying to install and perform an offline installation.
解决此问题的最简单方法是下载.jar您尝试安装的插件文件并执行离线安装。
Edit:I tried to find a link to a how-to, but eclipse.orgkept timing out on me.
编辑：我试图找到指向操作方法的链接，但eclipse.org一直超时。

I believe that you were getting these timeout problems during the rollout of 3.5.1. Eclipse.org had several server and mirroring issues during this time, and this caused manhy people to experience timeouts when trying to update.
我相信您在 3.5.1 推出期间遇到了这些超时问题。在此期间 Eclipse.org 有几个服务器和镜像问题，这导致许多人在尝试更新时遇到超时。
In the future, when you see problems like this, you can try installing from a specific mirror. I find that installing from here tends to work well even when Eclipse.org is not:
以后遇到这样的问题，可以尝试从特定的镜像安装。我发现即使 Eclipse.org 不是，从这里安装也能很好地工作：

The timeout is not the cause, it's just the symptom, there might be "zombie" entries in the update sites.
超时不是原因，只是症状，更新站点中可能存在“僵尸”条目。

After removing those with empty "name" column it should work (faster).
删除那些带有空“名称”列的内容后，它应该可以工作（更快）。
