Issue with 0.3.0-beta / Kotlin 1.3

[jmarinelli]

Hi! i'm having this weird issue trying to implement KGrapQL 0.3.0-beta using Kotlin's new release 1.3

I'm defining this schema:

val schema = KGraphQL.schema {

        configure {
            useDefaultPrettyPrinter = true
        }

        query("user") {
            description = "Returns a user by its phone number"

            resolver { phoneNumber: String ->
                userService.getByPhoneNumber(phoneNumber)
            }
        }
}

And when executing the following code:
val result = schema.execute("{user(phoneNumber:\"005491140632747\"){firstName}}")

I get the following stacktrace:

java.lang.NoSuchMethodError: kotlinx.coroutines.BuildersKt.launch$default(Lkotlin/coroutines/CoroutineContext;Lkotlinx/coroutines/CoroutineStart;Lkotlin/jvm/functions/Function1;Lkotlin/jvm/functions/Function2;ILjava/lang/Object;)Lkotlinx/coroutines/Job;

Of course I tried cleaning, re-building, with new projects, etc.

I'm kind of new with kotlin, so I do know if the coroutines API had big changes since the 1.3 release and RCs, but it feels like it might have something to do with that.

Thank you!

On it, expect a pull-request shortly

[vemilyus]

I've created a pull request #33 that takes care of those issues.

[pgutkowski]

@jmarinelli Addressed by #33 and merged, I've released new version: 0.3.0. Please upgrade.

Thanks! Great library btw!
