java - Eclipse 在抛出 "Throwable during asyncExec Malformed class name"后崩溃

Question

我的 Eclipse 工作台在抛出错误后关闭:

Throwable during asyncExec
Malformed class name

附上截图。

错误如下

Answer 1

这是一个使用 eclipse scala-IDE 和 maven 的已知问题。当你有一个案例类时，它就会发生。 https://github.com/scala/bug/issues/2034

复制案例类并将其放入 scala 对象类(如内部类)，不要将其放在对象类之外。

或者切换到intellij，据我所知，这些是唯一的解决方案
