kotlin - Kotlin java.lang.ArrayIndexOutOfBoundsException:448

Question

我正在学习 Kotlin，但我的电脑使用 Intellij 太糟糕了。我下载了 VSCODE 并遵循了所有步骤。我的意思是 Code Runner、Kotlin 语言扩展和添加到路径。但是当我跑来编写任何代码时。像这样

fun fun main(args: Array<String>) {
print("Hello")
}

VScode 返回此消息

您使用什么 Java 版本？试试看java -version。您可能需要 Java 11（或 8）。另外，我fun fun在代码片段中看到，可能是拼写错误

我发现了与 https://youtrack.jetbrains.com/issue/KT-21303相关的问题

尝试使用新版本的 Kotlin 编译器，例如1.3.21
