gradle - 在 Gradle 中禁用对使用 'kotlin' 包的检查

Question

当我尝试gradlew 构建 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

发生这种情况是因为我在包中声明了一个以以下内容开头的类:kotlin...

有没有办法通过配置我的 build.gradle 脚本来禁用此检查？

编辑:我确信如果我使用裸 kotlin 编译器编译这是可能的... here is an example使用 kotlin 编译器编译 kotlin 包中的类...所以我认为应该有一种方法可以在 gradle 中完成它!....我希望...

到目前为止我尝试了什么:

1. 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 脚本在这些更改下运行良好... but it seems like this is getting ignored ...我仍然遇到错误。

2. 我尝试子类化 KotlinCompile 类并覆盖它的 beforeCompileHook()并用我的版本替换现有的 compileKotlin 任务:

   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。我尝试过抛出和不抛出 RuntimeException 但当我再次尝试 gradle build 时，我总是收到以下错误:

   F:\IdeaProjects\walp.tinykotlintest>gradlew build --stacktrace
   :compileKotlin UP-TO-DATE

无论如何我可能不应该这样做...但我真的很想尝试一下。

谢谢!

如果 Kotlin 标准库与您正在使用的 JVM 不兼容，听起来您实际上应该做的是 fork Kotlin，进行与 JVM 兼容所需的更改，然后使用标准 Maven build script建立你的 fork 。该脚本已经提供了允许编译 kotlin 包中的文件的选项。
