Suppress all deprecation issues in Kotlin

Question

In my project, all Kotlin warnings are treated as errors. For that I use the following configuration:

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

However, I want to ignore deprecation errors, the same way I'm already doing in Java with -Xlint:all,-deprecation

However, I can't find any documentation explaining how to do so.

I've tried using the following configuration but with no success:

freeCompilerArgs = ["-Xjavac-arguments=['-Xlint:all,-deprecation']"]

This was taken from here but it doesn't seem to work and deprecation warnings are still considered errors

Is there any option I can use to disable deprecation issues this?

Thanks
