Hi, I hope this error makes sense to someone, because it’s got me stumped.

Exception in thread "main" java.lang.NoSuchMethodError: 'kotlinx.io.files.Path kotlinx.io.files.FileSystem.resolve(kotlinx.io.files.Path)'
	at io.ktor.server.engine.ServerEngineUtilsKt.<clinit>(ServerEngineUtils.kt:9)
	at io.ktor.server.engine.EmbeddedServerKt.embeddedServer$default(EmbeddedServer.kt:73)
	at com.greymatter.sfad.ApplicationKt.main(Application.kt:9)
	at com.greymatter.sfad.ApplicationKt.main(Application.kt)

package com.greymatter.sfad

import com.greymatter.sfad.plugins.*
import io.ktor.server.application.*
import io.ktor.server.engine.*
import io.ktor.server.netty.*

fun main() {
    embeddedServer(Netty, port = 8080, host = "0.0.0.0", module = Application::module)  // line 9
        .start(wait = true)
}

fun Application.module() {
    configureSecurity()
    configureHTTP()
    configureMonitoring()
    configureSerialization()
    configureDatabases()
    configureSockets()
    configureAdministration()
    configureRouting()
}

It might help to know that this is a multi-rooted project that began as a Multiplatform project, and I just decided to switch the backend to Ktor and the frontend to KMP Web, so the whole thing is in flux. This could be related to something I’ve done wrong in one of the build.gradle.kts files. Any clues would be greatly appreciated.

Looks like a classpath issue. Make sure kotlinx-io is in your runtime classpath (and also double check the version?)

I generated a project at https://start.ktor.io, and even it won’t run.

% ./gradlew run

What configuration did you use?

It works for me using the default. If you can reproduce, file a Youtrack?
