Java 8 java8和Kotlin出现错误

我有一个应用程序，我正在使用retrolambda，所以在build.gradle中我有

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

除非我添加对Kotlin的支持，否则一切都很好。 添加Kotlin插件时出现以下错误：

错误：将字节码转换为索引时出错： 原因：Dex无法解析版本52字节代码。 这是由使用Java8或更高版本编译的库依赖项引起的。 如果您在库子模块中使用“java”gradle插件，请添加 targetCompatibility='1.7' sourceCompatibility='1.7' 到该子模块的build.gradle文件

我发现许多问题和答案与此类似，但没有一个解决方案适用于我的情况

我尝试了这个，但没有成功

tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile).all {
    sourceCompatibility = JavaVersion.VERSION_1_6
    targetCompatibility = JavaVersion.VERSION_1_6

    kotlinOptions {
        jvmTarget = '1.6'
        apiVersion = '1.1'
        languageVersion = '1.1'
    }
}

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'
    }
}

而这

tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile).all {
    sourceCompatibility = JavaVersion.VERSION_1_6
    targetCompatibility = JavaVersion.VERSION_1_6

    kotlinOptions {
        jvmTarget = '1.6'
        apiVersion = '1.1'
        languageVersion = '1.1'
    }
}

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'
    }
}

更新 对于kotlin使用1.8的上一个版本，我现在得到一个不同的错误：

错误：任务“：app:compiledBugkotlin”的执行失败。 编译错误。有关更多详细信息，请参阅日志

Retrolambda没有处理Kotlin字节码，您应该将Kotlin编译器设置为专门针对1.6字节码。这不会破坏Kotlin当前版本中的任何内容，因为它可以为相同的功能生成较旧的字节码

compileKotlin {
    kotlinOptions.jvmTarget = "1.6"
}

这记录在

对于测试，还应添加：

compileTestKotlin {
    kotlinOptions.jvmTarget = "1.6"
}

您应该提及您尝试的哪些解决方案无效。“但没有一个解决方案适用”意味着人们可能会在不知道他们是什么的情况下再次告诉你同样的事情。@JaysonMinard很容易看出他们不适用，因为我已经在做他们在代码中建议的事情了
