Cannot access built-in declaration Ensure that you have a dependency on the Kotlin standard library

Error:(11, 40) Kotlin: Cannot access built-in declaration 'kotlin.coroutines.SuspendFunction1'. Ensure that you have a dependency on the Kotlin standard library

fun Route.coroutineHandler(fn: suspend (RoutingContext) -> Unit) {
    handler { ctx ->
        launch(ctx.vertx().dispatcher()) {
            try {
                fn(ctx)
            } catch (e: Exception) {
                ctx.fail(e)
            }
        }
    }

Like Slaw commented just add the kotlinx-coroutines-core dependency to your project as described in the README

Maven

Add dependencies (you can also add other modules that you need):

<dependency>
    <groupId>org.jetbrains.kotlinx</groupId>
    <artifactId>kotlinx-coroutines-core</artifactId>
    <version>1.3.5</version>
</dependency>

And make sure that you use the latest Kotlin version:

<properties>
    <kotlin.version>1.3.70</kotlin.version>
</properties>

Gradle

Add dependencies (you can also add other modules that you need):

dependencies {
    implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-core:1.3.5'
}

And make sure that you use the latest Kotlin version:

buildscript {
    ext.kotlin_version = '1.3.70'
}

Make sure that you have either jcenter() or mavenCentral() in the list of repositories:

repository {
    jcenter()
}
