IntelliJ 新 JavaFX 项目未完成工作 - InvalidModuleDescriptorException

我刚刚安装： IntelliJ IDEA 2021.2.3（社区版）和 jdk-16.0.2

在 IntelliJ 中我创建一个新项目：

文件->新建->项目

然后选择：

语言：科特林，

构建系统：Gradle，

项目SDK，16版本16.0.2

其他一切我都保持原样。

它创建了项目。

我去HelloApplication.kt并点击功能旁边的“播放main()” 。

我收到此错误：

Error occurred during initialization of boot layer java.lang.module.FindException: Error reading module: C:\Users\User\IdeaProjects\demo\build\classes\java\main Caused by: java.lang.module.InvalidModuleDescriptorException: Package com.example.demo not found in module

谁能指导我如何让它工作？为什么这个项目不能开箱即用？

javafx intellij-idea gradle kotlin

Kodein + Ktor = 冻结 kotlin.collections.HashMap 的突变尝试 - 为什么？

最近几天，我一直在为这个例外而苦苦挣扎。

我有一个具有这些依赖项的 kotlin 多平台项目：

科特林 = 1.5.10
编码=7.6.0
ktor=1.6.0（内部使用 kotlin 协程 1.5.0-native-mt）

在尝试在本机中使用 httpClient 时，我一直被提到异常：

我设法在测试中重现了该崩溃：
