Intellij 拒绝将 Kotlin 目标 jvm 设置为 1.8？

ParallelStreams.kts:41:15: error: calls to static methods in Java interfaces are prohibited in JVM target 1.6. Recompile with '-jvm-target 1.8'
IntStream.range(0,10).parallel().forEach{a ->
         ^

好吧...我不想编译 1.6。

File > Project Structure > Project有项目sdk1.8和语言水平8.

File > Project Structure > Modules > Kotlin有目标平台：JVM 1.8.

我的 gradle 构建文件...

plugins {
    id 'org.jetbrains.kotlin.jvm' version '1.3.0'
}

group 'foo'
version '1.0-SNAPSHOT'

repositories {
    mavenCentral()
}

dependencies {
    //kotlin
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8"
    implementation "org.jetbrains.kotlin:kotlin-script-runtime:1.3.0"

    //networking
    implementation 'com.mashape.unirest:unirest-java:1.4.9'
}

compileKotlin {
    kotlinOptions.jvmTarget = "1.8"
}
compileTestKotlin {
    kotlinOptions.jvmTarget = "1.8"
}

我已经没有地方可以检查了1.8.

是的，我have尝试使缓存失效并重新启动 Intellij。它对解决这个问题没有任何作用。

Add sourceCompatibility and targetCompatibility对于 Java 1.8：

plugins {
  id 'org.jetbrains.kotlin.jvm' version '1.3.0'
}

group 'foo'
version '1.0-SNAPSHOT'

repositories {
  mavenCentral()
}

// Add compatibility
sourceCompatibility = JavaVersion.VERSION_1_8
targetCompatibility = JavaVersion.VERSION_1_8


dependencies {
  //kotlin
  implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8"
  implementation "org.jetbrains.kotlin:kotlin-script-runtime:1.3.0"

  //networking
  implementation 'com.mashape.unirest:unirest-java:1.4.9'
}

compileKotlin {
  kotlinOptions.jvmTarget = "1.8"
}
compileTestKotlin {
  kotlinOptions.jvmTarget = "1.8"
}
