Add this config to your build.gradle (note that ... means whatever is already there) :

Groovy:

compileKotlin {
    kotlinOptions {
        freeCompilerArgs = [..., "-Xemit-jvm-type-annotations"]
        ...
    }
}

Kotlin DSL:

tasks.withType {
    kotlinOptions {
        freeCompilerArgs = listOf(..., "-Xemit-jvm-type-annotations")
        ...
    }
}
