Kotlin Gradle构建未解决对Kotlin-stdlib函数的引用问题

Question

我有以下用于我的软件包的build.gradle文件。

buildscript {
    ext.kotlin_version = '1.2.21'

    repositories {
        jcenter()
        mavenCentral()
    }

    dependencies {
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    classpath "org.jetbrains.kotlin:kotlin-stdlib"
    }
}

plugins {
    id "org.jetbrains.kotlin.jvm" version "1.2.21"
}

sourceSets {
    main.kotlin.srcDirs += "./"
}

在运行gradle compileKotlin时，我遇到了以下错误。

当我使用kotlinc -include-runtime命令编译此包时，它可以顺利编译，我甚至得到了一个可用的.jar文件。

我错过了什么吗？如果您想进一步查看，我还创建了一个GitHub问题，其中包含相关代码的链接。

您需要添加这个依赖项：

dependencies {
    compile "org.jetbrains.kotlin:kotlin-stdlib"
}

在顶层位置，而不是buildscript内部：

buildscript {
    ext.kotlin_version = '1.2.21'

    repositories {
        jcenter()
        mavenCentral()
    }

    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

plugins {
    id "org.jetbrains.kotlin.jvm" version "1.2.21"
}

dependencies {
    compile "org.jetbrains.kotlin:kotlin-stdlib"
}

sourceSets {
    main.kotlin.srcDirs += "./"
}

正如已经提到的那样，依赖项必须放在buildscript之外的dependencies块中。但是，您还必须指定要使用的stdlib版本：

buildscript{
    ...
}
dependencies{
    compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
}
