Unresolved reference: launch

Question

Trying to run some examples for Kotlin coroutines, but can\'t build my project. I\'m using the latest gradle release - 4.1

Any suggestions what to check/fix?

Launch isn't used anymore directly. The Kotlin documentation suggests using:

fun main() { 
    GlobalScope.launch { // launch a new coroutine in background and continue
        delay(1000L)
        println("World!")
    }
    println("Hello,") // main thread continues here immediately
    runBlocking {     // but this expression blocks the main thread
        delay(2000L)  // ... while we delay for 2 seconds to keep JVM alive
    } 
}
