注意：我经历了所有的可能性——marketplace.eclipse.org/catalogs/api*（不工作）——将“Active Provider”更改为“Manual”/“Direct”（不工作）——禁用代理条目/绕过（不工作）

For me I solved the problem by those steps:
对我来说，我通过以下步骤解决了这个问题：
Use the CNTLM proxy, which can be installed and run by following this GitHub readme file.
Go to-Window->Preferences->General->Network Connections
Click on an empty line and add a host and the same port that youn configured in CNTLM
使用 CNTLM 代理，可以按照此 GitHub 自述文件安装和运行。
转到-窗口->首选项->常规->网络连接
单击空行并添加主机和您在 CNTLM 中配置的相同端口

I tried all the suggestions but no success for Eclipse Neon and Oxygen. At last it worked for Eclipse Neon when I added below line in Configuration Settings in eclipse folder.
我尝试了所有建议，但 Eclipse Neon 和 Oxygen 没有成功。最后，当我在 eclipse 文件夹的 Configuration Settings 中添加以下行时，它适用于 Eclipse Neon。
-Djava.net.preferIPv4Stack=true
-Djava.net.preferIPv4Stack=true
Edit Configuration Settings in eclipse folder and add the below line and save it. It will work.
在 eclipse 文件夹中编辑配置设置并添加以下行并保存。它会起作用。

I tried all the suggestion above with Eclipse Photon. None worked. Finally got the marketplace to open by installing Eclipse to a path with no white spaces.
我用 Eclipse Photon 尝试了上面的所有建议。没有一个工作。最终通过将 Eclipse 安装到没有空格的路径来打开市场。

when launching, java application defaults to listening to ipv6 exclusively. Modify .ini configuration settings file present in the folder by adding -Djava.net.preferIPv4Stack=true below the -vmargs. This sets the java to prefer IPV4 stack.
启动时，java应用默认只监听ipv6。通过在 -vmargs 下方添加 -Djava.net.preferIPv4Stack=true 来修改文件夹中的 .ini 配置设置文件。这将 java 设置为更喜欢 IPV4 堆栈。
