导入协同程序 - 常见原因错误“无法将使用JVM目标1.8构建的字节码内联到...”。即使明确指定了jvmTarget

Question

我正试图在我的春季项目中导入kotlin协同程序。

我的build.gradle文件中有以下几行：

compileKotlin {
    kotlinOptions {
        freeCompilerArgs = ['-Xjsr305=strict']
        jvmTarget = '1.8'
    }
}

compileTestKotlin {
    kotlinOptions {
        freeCompilerArgs = ['-Xjsr305=strict']
        jvmTarget = '1.8'
    }
}

但无论如何，当我导入协同程序 - 常见使用implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-common:1.1.1'我得到错误：Cannot inline bytecode built with JVM target 1.8 into bytecode that is being built with JVM target 1.6. Please specify proper '-jvm-target' option

如果我删除implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-common:1.1.1'项目建设正常。

我怎样才能导入kotlin协同程序？

附：我试过了

tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile).all {
    kotlinOptions { 
        apiVersion = "1.3"
        languageVersion = "1.3"
        jvmTarget = "1.8"
    }
}

Answer 1

依赖org.jetbrains.kotlinx:kotlinx-coroutines-common:1.1.1是错误的。

请改用org.jetbrains.kotlinx:kotlinx-coroutines-core-common:1.1.1。
