如何在Kotlin Native中导入Java包 [英] How to import Java packages in Kotlin Native

问题描述

我正尝试导入Java包，以用于Kotlin本机，如下所示；

I'm trying to import Java package for use in Kotlin native as below;

/* main.kt */
import java.util.*

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

并使用以下命令进行编译

and compile it with the below command

kotlinc main.kt -o main

我收到了错误消息

main.kt:2:8: error: unresolved reference: java
import java.util.*

很显然，我需要向kotlinc显示在哪里可以找到java.util，如何在不使用命令行的情况下实现这一点?我在Windows 10 64位上使用Kotlin本机0.3.

obviously I need to show kotlinc where to find java.util, how can I achieve this without using the command line? I'm on Windows 10 64 bit using Kotlin native 0.3.

推荐答案

您将无法访问Kotlin Native中的Java软件包.该项目的全部重点是在没有VM的情况下运行Kotlin代码，因此您无需使用Java虚拟机(或库).但是，您可以改用本机C库.您可以在此处找到相关信息.

You won't have access to Java packages in Kotlin Native. The whole point of this project is to run Kotlin code without a VM, so you don't have the Java Virtual Machine (or libraries) to use. You can, however, use native C libraries instead. You can find information about how this works here.

从公告发布 Kotlin/Native的第一个预览:

From the announcement post of the first preview of Kotlin/Native:

请注意，我们不打算使任意Kotlin/JVM程序可在Kotlin/Native或Kotlin/JS上运行.这将等效于实现另一个JVM，这既工作量大，运行时也有很多限制.我们正在采取另一种方式:为所有平台提供一种通用语言，同时通过与平台代码的无缝互操作性来创建通用库.

Note that we do not intend to make arbitrary Kotlin/JVM programs runnable on Kotlin/Native or Kotlin/JS. It would be equivalent to implementing another JVM, which is both a lot of work and a lot of limitations for the runtime. We are going another way: providing a common language for all platforms while enabling creation of common libraries through seamless interoperability with platform code.
