Thanks for your reply! It does not seem to work. I want to add a getEnv method, which throws an Exception if the environment variable does not exists.

Define a top-level function

👆 1

Something like this:

fun getEnv(key: String) = when {
    System.getenv().containsKey(key) -> System.getenv(key)
    else -> throw Exception("w/e exception you want")
}

That's how

println

is implemented. On the JVM it's just a top-level function wrapping

System.out.println

I would probably prefer something like

System.getenv(key) ?: throw Exception("missing env $key")
