我正在尝试几天来构建我的android项目(主要包含kotlin)...我试图改变所有版本的版本,并且我在构建时不断收到同样的错误!

我得到的消息看起来像这样:

Kotlin编译器:

org.jetbrains.kotlin.codegen.CompilationException: Back-end (JVM) Internal error: wrong code generated

Java编译器:

org.jetbrains.kotlin.codegen.CompilationException: Back-end (JVM) Internal error: Couldn't transform method node:

java.lang.IllegalArgumentException

我没有做任何可能导致它发生的戏剧性变化......我试图重建,清理,删除所有内容,更改所有版本的版本,但我仍然无法摆脱它.

我怎么解决这个问题？

谢谢!

我正在使用Firebase Cloud Firestore，我希望当我获得一个内部包含引用字段的文档时，将引用字段作为文档接收，而不是作为对文档的引用...

我有一个用户集合和类集合（在学校），每个类都包含对用户（该类中的学生）的引用列表。当我使用document.get()（通过引用获取类）时，它返回一个包含DocumentReference（用户）列表的对象，因此我需要再调用document.get()大约 20 次才能将用户作为对象而不是作为对他们的引用。

我希望能够调用document.get()一次，它会将所有引用作为文档带给我，例如： 数据库和代码

有没有一种优雅的方法来做到这一点？
