Solution 1:

The warnings that you see are reported by the Kotlin compiler, not by Android Lint, so lintOptions won't affect them.

Instead, if you want to suppress the warnings, you can configure a single Kotlin compilation task to suppress its warnings:

compileDebugKotlin {
    kotlinOptions.suppressWarnings = true
}

Or suppress the warnings from all Kotlin compilation tasks:

tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile).all {
    kotlinOptions.suppressWarnings = true
}

Though in fact, these warnings should not affect the build performance in any noticeable way.
