后端 (JVM) 内部错误。为什么我会收到此 IDE 错误，而具有相同代码的其他人却不会？

Question

我是使用 Kotlin 开发程序的小组的一员。我最近从开发分支中提取了新代码。问题是我得到了这个奇怪的错误。我是唯一得到它的人；我的队友有相同的代码，并且对他们来说运行良好。

我已经尝试用谷歌搜索错误。我没有找到任何帮助，因为它非常具体。另外，就像我说的，我的队友不会收到此错误。因此它可能与代码无关。

我得到的错误是这样的：

我确定这与我的 IDE 或某些本地设置有关。同样，我的队友没有收到此错误。错误 EndRoundState.kt 中提到的文件看起来像这样。如果这有助于澄清我的问题。

我只想让代码在我的机器上编译，就像它为我的同事所做的那样。它确实通过 Maven 编译，而不是通过 IntelliJ。

非常感谢！

Answer 1

我通过卸载 IntelliJ 包括所有 settings/plugins 并重新安装解决了这个问题。卸载 IDE 而不删除 settings/plugins 无效。

Answer 2

我通过升级 kotlin 插件修复了。我的插件版本目前是 1.3.41-release-IJ2018.2-1

Answer 3

我在我们的一个测试用例中遇到过这个问题，我们的函数名称很长。假设这台开发机器是 Windows 10 机器，并且 Windows 有长文件名问题的历史，https://community.spiceworks.com/topic/2006950-file-path-too-long-shortening-names-is-only-the-solution.

尝试查看文件名或函数名是否太长并缩短。它确实帮助我将 93 个字符的测试函数名称减少到 70 个字符。

还要检查您是否使用了奇怪的字符和表情符号，有时它们会扰乱文件生成。

玩得开心，注意安全。

Answer 4

在我的例子中，这是由于使用我的自定义 suspend operator fun plusAssign 并通过 += 调用它造成的。当我 将 += 替换为显式 plusAssign 时，它可以正常编译。我也可以在其他地方使用相同的 += 就好了。不知道发生了什么。

后端 (JVM) 内部错误。为什么我会收到此 IDE 错误，而具有相同代码的其他人却不会？

Back-End (JVM) internal error. Why do i get this IDE error but others with the same code do not?
