在Eclipse中通过RSE插件运行远程java程序时遇到问题

Question

我花了很多时间搞清楚如何使用RSE插件从本地Eclipse运行远程Java程序.

我能够使用RSE通过eclipse连接到我的远程机器,Create Remote Project在Remote System Explorer透视后在eclipse上进行远程maven项目之后,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,它会抛出一个错误,

我花了一天时间来弄清楚问题是什么.如果有人之前遇到过这个问题,或者可以对这个问题有所了解,那么这将是非常值得注意的.

另外,如果您需要更多信息,请告诉我？

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，您可能仍然处于暴风雪中，但至少您不会盲目飞行。
