Android Studio在Kotlin项目中引发构建错误，该项目在Java接口中调用静态方法 [英] Android Studio throws build error in Kotlin project which calls static method in java interface

问题描述

我在Android Studio中有一个Kotlin项目.我正在从Kotlin代码在Java接口中调用静态方法.构建因错误而失败，

I have a Kotlin project in Android Studio. I am calling a static method in Java interface from the Kotlin code. The build fails with the error,

Calls to static methods in Java interfaces are prohibited in JVM target 1.6. Recompile with '-jvm-target 1.8'

我的 build.gradle 中有以下内容，

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

我还在Kotlin编译器设置中将Target JVM版本更改为1.8.尽管如此，该构建仍会引发错误.还尝试了使缓存无效并重新启动.

I have also changed the Target JVM version to 1.8 in Kotlin compiler settings. Still, the build throws the error. Also tried Invalidating cache and restarting.

Android Studio版本:3.0.1

Android Studio version: 3.0.1

推荐答案

在android gradle中设置Kotlin编译选项的正确方法. 对您的应用程序级别进行这些更改 Build.gradle

Proper way to set Kotlin compile options in android gradle. Make these changes to your app level Build.gradle

更改

实现"org.jetbrains.kotlin:kotlin-stdlib-jre7:$ kotlin_version"

implementation "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"

到

implementation "org.jetbrains.kotlin:kotlin-stdlib-jre8:$kotlin_version"

然后编写此任务

tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile).all {
    sourceCompatibility = JavaVersion.VERSION_1_8
    targetCompatibility = JavaVersion.VERSION_1_8

    kotlinOptions {
        jvmTarget = '1.8'
        apiVersion = '1.1'
        languageVersion = '1.1'
    }
}

就在下面(不一定)

repositories {
    mavenCentral()
}
