java - 在 Eclipse 中通过 RSE 插件运行远程 Java 程序时遇到问题

Question

我花了很多时间弄清楚如何使用 RSE 插件从本地 Eclipse 运行远程 Java 程序。

我能够使用 RSE 通过 eclipse 连接到我的远程计算机，并且在 Remote System Explorer 透视图上对 eclipse 上的远程 maven 项目执行 Create Remote Project 之后，我可以在 Java Perspective 下看到我的项目。

现在在 Java Perspective 下，当我继续创建一个构成 Hello World 程序的简单 java 文件时，它抛出一个错误，

我花了整整一天的时间来弄清楚问题出在哪里。如果有人以前遇到过这个问题，或者可以对这个问题有所了解，那将是非常值得赞赏的。

此外，如果您需要更多信息，请告诉我？

谢谢回溯到工作区.metadata目录下的.log

我会启动 Wireshark 来检查网络上到底发生了什么。事实上，你在暴风雪中盲目飞行。使用 Wireshark，您可能仍在暴风雪中，但至少不会盲目飞行。
