Question

我的包

有以下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，我收到以下错误

当我使用kotlinc -include-runtime命令编译这个包时，它编译没有任何问题，我甚至有一个工作.jar文件。

我在这里缺少什么？如果您想要进行更多检查，我还为此创建了github issue，其中包含指向相关代码的链接。

Answer 1

你需要把这种依赖：

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

位于顶层，而不是buildscript：

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 += "./"
}

Answer 2

如前所述，依赖项必须放在buildscript之外的依赖项块中。但是，您还必须指定要使用的stdlib的版本：

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

Kotlin gradle构建对kotlin-stdlib函数的未解析引用
