【问题讨论】：

主机名“evy01-proxy.eu.accor.net”对您有意义吗？ 是proxy的url Can't access Eclipse marketplace 的可能重复项 这是当代解决方案***.com/a/34204939/715269。 （从 4.3 版本开始）。那里的另一个答案适用于旧版本。 【参考方案1】：

对于某些代理服务器，Eclipse 4.4 使用的 HttpClient 库似乎存在问题。解决方法是通过将此行放入 eclipse.ini 中来使用 JRE http 客户端：

-Dorg.eclipse.ecf.provider.filetransfer.excludeContributors=org.eclipse.ecf.provider.filetransfer.httpclient4

Eclipse bug discussion

Disabling Apache HttpClient

【讨论】：

eclipse 4.3 或更高版本配置的正确参数将是-Dorg.eclipse.ecf.provider.filetransfer.excludeContributors=org.eclipse.ecf.provider.filetransfer.httpclient4，末尾为 4。不过谢谢！这对我有用。 我尝试安装此软件download.eclipse.org/rt/ecf/httpclient4/…，并按照“Eclipse 错误讨论”中的海报所述重新启动 Eclipse，并且成功了。 @SyAu：似乎代理身份验证在此安装后消失了。但是，安装像 Grails 这样较重的插件仍然会在中间抛出一堆读取超时错误。【参考方案2】：

我尝试了所有对我不起作用的东西。最后我发现，你必须允许来自 windows 防火墙（Windows 7）的 eclipse。

->转到控制面板>系统和安全>windows防火墙>允许程序或功能通过windows防火墙

->然后浏览eclipse.exe

->重启eclipse

【讨论】：

【参考方案3】：

1.转到

窗口->首选项->常规->网络连接。

2。更改设置

Active Provider-> Manual-> 并检查---> HTTP, HTTPS and SOCS

重启 Eclipse 并享受吧！

【讨论】：

【参考方案4】：

在 linux64 上，我与 luna 有类似的问题，而 Kepler 连接正常。 我在某处看到您应该清除网络连接中的 SOCKS 条目并处于手动 Active Provider 中。 然后重新启动 Eclipse 以应用更改。 它对我有用。

【讨论】：

谢谢丹尼斯，我在 ubuntu 64 中遇到了类似的 luna 问题，清除系统网络代理中的 socks 条目就像一个魅力。 :) 霓虹灯也是如此。谢谢！【参考方案5】：

只需在 eclipse.ini 中添加这一行

Dorg.eclipse.ecf.provider.filetransfer.excludeContributors=org.eclipse.ecf.provider.filetransfer.httpclient4

然后重启eclipse！

如果仍然存在，请检查Tools &gt; preferences &gt; general &gt; Network connections中的网络连接参数

【讨论】：

【参考方案6】：

我找到了解决方案。我更改了我的 Eclipse 版本。我现在使用 Eclipse Indigo，因为所有 4.x 版本都不能在我的计算机上运行。提醒一下，我使用的是 Windows XP 32 位...史前机器。

【讨论】：

我不认为降级 Eclipse 是最好的解决方案。一般来说，降级任何东西都是最后的手段，因为您缺少修复、更新等。
