我最近转向Eclipse 2020-06进行JEE开发，事实证明这是一个挫折。无论何时需要采取措施，它都会保持冻结状态：进入类定义，按ctrl键并选择任何项（类，方法等）。蚀日志充满了这些错误：

我当前使用的插件是JBoss Tools，Spring STS，Subeclipse和Dark Theme。 我试图再次下载整个IDE，并取消选中有关验证的大多数选项，但无济于事。有什么想法吗？

非常感谢您！

转到Windows->首选项->语言服务器。禁用所有复选框，应用并关闭。重新启动IDE。它为我解决了问题。

答案 1 :(得分：0)

就我而言，它是 Language Servers 中的“Camel LSP server for java”。禁用后，GUI 再次响应

答案 2 :(得分：-1)

重新启动 IDE 将解决此问题。
