【问题讨论】：

  • 您是否使用代理连接到互联网？
  • 通过网络连接我选择手动设置HTTP。我也尝试了其他两个选项 Native 和 direct 但未连接。
  • 这是否意味着“是的，我必须使用代理才能连接到 Internet”？
  • 是的，我必须使用连接。

标签： java eclipse


【解决方案1】：

设置代理时，请确保选择Active Provider: Manual，然后再次检查您的代理设置（主机和端口）。我在工作站上将 Eclipse 连接到 Internet 时遇到了类似的问题，结果问题出在 Active Provider 设置上。

【讨论】：

  • 我检查它是正确的。我打开了eclipse的网络浏览器并打开了google，它是打开的问题是当页面打开时立即eclipse退出。
【解决方案2】：

有时您需要采取不同的方法来告诉 Eclipse 需要使用哪个代理：

-Dhttps.proxyPort=8080
-Dhttps.proxyHost=name.of.proxy
-Dhttp.proxyPort=8080
-Dhttp.proxyHost=name.of.proxy

你可以把它放到你的 eclipse.ini 中。

如果您的代理需要您进行身份验证并且仅支持 Windows 凭据，那么引入一个像 CNTLM 这样的中间代理可能会有所帮助。 CNTLM 然后接收您的凭据以通过代理进行身份验证，并为您的应用程序提供一个代理，该代理不需要需要身份验证。但如果您需要，这取决于您的设置。

【讨论】：

  • 谢谢，我试过了，但还不行。我编辑了当我再次运行 eclipse 时得到的问题的代码，你能再次检查代码吗？
  • 查看this链接以获取有关如何安装cntlm的详细步骤，您需要将系统代理设置指向ctlm服务器localhost：3128（默认端口）
【解决方案3】：

Marged 的​​答案是对的，但你必须设置

-Dhttps.proxyPort=8080
-Dhttps.proxyHost=name.of.proxy
-Dhttp.proxyPort=8080
-Dhttp.proxyHost=name.of.proxy

在您的小程序内运行配置 WM 参数。 运行配置 > 参数 > VM 参数

【讨论】：

    【解决方案4】：

    您可以通过使用任何 VPN 服务来避免它，您的 IP 发出了太多请求，很可能是因为您在制作项目时经常使用它，谷歌认为它是一个系统产生的重复请求。 你可以通过使用VPN暂时避免它。享受..!!
