Cannot inline bytecode built with JVM target 1.8 into bytecode that is being built with JVM target 1.6

app/build.gradle

android {
    ...
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

    kotlinOptions {
        jvmTarget = JavaVersion.VERSION_1_8.toString()
    }
}

Use Java 8 language features

You can fix this issue as follows:

• Open the IntelliJ preferences
• Go to Build, Execution, Deployment > Compiler > Kotlin Compiler BUT Other Settings > Kotlin compiler if Android Studio > 3.4
• Change the Target JVM version to 1.8
• Click Apply

you should configure something like as follows in build.gradle

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