Java version setting not being respected by the build

Help/Discuss
1

I am unable to set jvmTargets for Android. It is complaining that Calls to static methods in Java interfaces are prohibited in JVM target 1.6. Recompile with '-jvm-target 1.8'

I want to add kotlinOptions { jvmTarget = "1.8" } but I have been unable to.

I already have following compileOptiosns but isn’t enough.

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

Here are my two gradle files:

buildscript {
    ext {
        kotlin_version = '1.3.41'
        ktor_version = '1.2.2'
        gradle_version = '3.4.2'
    }

    repositories {
        google()
        jcenter()
        maven { url 'https://dl.bintray.com/kotlin/kotlin-dev' }
        maven { url 'https://dl.bintray.com/kotlin/kotlin-eap' }
    }
    dependencies {
        classpath "com.android.tools.build:gradle:$gradle_version"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

    }
}

allprojects {
    repositories {
        google()
        jcenter()
