scala - Gradle Kotlin DSL Scala和想法

Question

我该如何设定

idea {
    targetVersion = "13"
}

和

sourceCompatibility = 1.8

从scala插件https://docs.gradle.org/current/userguide/scala_plugin.html使用gradle kotlin dsl构建时？

Answer 1

设置IDEA的目标版本是一个简单的复制粘贴:
build.gradle:

idea {
    targetVersion = "13"
}

build.gradle.kts:

idea {
    targetVersion = "13"
}

设置sourceCompatibility有点棘手:
build.gradle:

sourceCompatibility = 1.8

build.gradle.kts:

 tasks.withType<ScalaCompile> {
     sourceCompatibility = "1.8"
 }

但是请注意，Gradle Scala plugin docs声明sourceCompatibility选项基本上是无操作的。兼容的Java版本由Scala编译器确定，其中2.11.x针对Java 1.6，而2.12.x针对Java 1.8
