Intellij拒绝将Kotlin目标jvm设置为1.8? [英] Intellij refuses to set the Kotlin target jvm to 1.8?

问题描述

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...我不是要为1.6编译.

Ok ... I'm not trying to compile for 1.6.

File > Project Structure > Project具有项目sdk 1.8和语言级别8.

File > Project Structure > Project has project sdk 1.8 and language level 8.

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

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

File > Settings > Compiler > Kotlin Compiler具有目标jvm版本1.8.

File > Settings > Compiler > Kotlin Compiler has target jvm version 1.8.

我的gradle构建文件...

My gradle build file ...

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"
}

我没有地方去检查1.8.

是的，我 已经 尝试使缓存无效并重新启动Intellij.它无能解决此问题.

And yes, I have tried invalidating the cache and restarting Intellij. It does nothing to resolve this issue.

推荐答案

使用.kts只需使用此:

tasks {
    withType<KotlinCompile> {
        kotlinOptions.jvmTarget = "1.8"
    }
}

// I am using latest dsl and gradle 
val kotlinVersion = "1.3.30"
val gradleVersion = "5.4+"
