Question

当我尝试gradlew build我的项目时，我收到来自compileKotlin任务的错误消息：

F:\IdeaProjects\walp.tinykotlintest>gradlew build
:compileKotlin
...
Only the Kotlin standard library is allowed to use the 'kotlin' package
...

BUILD FAILED 

Total time: 6.214 secs

这是因为我在一个以kotlin ...

开头的包中声明了一个类

有没有办法通过配置我的build.gradle脚本来取消此检查？

编辑：我知道如果我使用kotlin编译器使用kotlin编译器编译一个类来编译一个类... here is an example，我可以肯定这是可能的。所以我认为应该这样做也是一种在gradle中做到这一点的方法！....我希望......

到目前为止我尝试过：

我尝试通过配置KotlinCompile任务来配置gradle.build：
```
import org.jetbrains.kotlin.gradle.tasks.KotlinCompile

tasks.withType(KotlinCompile) {
    it.kotlinOptions.allowKotlinPackage = true
}
```
gradle脚本可以正常运行这些更改... but it seems like this is getting ignored ...我仍然遇到错误。

我尝试将KotlinCompile类子类化并覆盖其beforeCompileHook()并将现有的compileKotlin任务替换为我的版本：

import org.jetbrains.kotlin.cli.common.arguments.K2JVMCompilerArguments
import org.jetbrains.kotlin.gradle.tasks.KotlinCompile

class MyKotlinCompile extends KotlinCompile {
    @Override
    public void beforeCompileHook(K2JVMCompilerArguments args) {
        args.allowKotlinPackage = true
        throw new RuntimeException("HELLO") // added to see if hook is run
    }
}

tasks.create(name: "compileKotlin", type: MyKotlinCompile, overwrite: true)

Studying the source code...I was fairly certain this would work但显然没有。我尝试了不使用RuntimeException，但是当我再次尝试gradle build时，我总是遇到以下错误：

F:\IdeaProjects\walp.tinykotlintest>gradlew build --stacktrace

我可能不应该这样做......但我真的想尝试一下。

Answer 1

如果Kotlin标准库与您正在使用的JVM不兼容，那么听起来您应该实际执行的是fork Kotlin，进行与JVM兼容所需的更改，然后使用标准{{3}构建你的fork。该脚本已提供允许编译kotlin包中的文件的选项。

Answer 2

该错误与Gradle无关。 Kotlin编译器不会在kotlin包中编译代码，除非您正在开发Kotlin本身。

这样做是因为您无法在java包中编写代码。

禁用在Gradle中使用'kotlin'包检查
