Hi! I started getting deprecation warnings when using Ktor on random functions that are not themselves deprecated:
get(...) is deprecated. Experimental coroutines support will be dropped in 1.4
in the simpliest code like

routing {
            get("/") {
                call.respondText("Hello World!", ContentType.Text.Plain)
            }
            get("/demo") {
                call.respondText("HELLO WORLD!")
            }
        }

How do I get rid of those?

[cy]

You have old coroutines somewhere

[cy]

Don't mix Kotlin 1.3 with old coroutines/ktor

[voddan]

@cy I use ktor 0.9.5 since it is the last release I see on github. Should I use another version?

[cy]

0.9.5 works with Kotlin 1.2

[cy]

You can try 1.0.0-alpha-1 with Kotlin 1.3.0-rc-131

[voddan]

plugins {
    id 'org.jetbrains.kotlin.jvm' version '1.3.0-rc-131'
    id 'application'
}

group 'kotlin.examples.ktor'
version '1.0-SNAPSHOT'

repositories {
    maven {     url '<http://dl.bintray.com/kotlin/kotlin-eap>' }
    mavenCentral()
    jcenter()
    maven { url "<https://dl.bintray.com/kotlin/ktor>" }
}

ext.ktor_version = '1.0.0-alpha-1'
ext.coroutines_version = '0.30.2'

dependencies {
    compile "org.jetbrains.kotlin:kotlin-stdlib-jdk8"
    compile "io.ktor:ktor-server-netty:1.0.0-alpha-1 "
    compile "ch.qos.logback:logback-classic:1.2.3"
//    compile 'org.jetbrains.kotlinx:kotlinx-coroutines-core:0.30.2'
//    compile 'org.jetbrains.kotlinx:kotlinx-coroutines-jdk8:0.30.2'
}

sourceCompatibility = 1.8
compileKotlin { kotlinOptions.jvmTarget = "1.8" }
compileTestKotlin { kotlinOptions.jvmTarget = "1.8" }

//kotlin.experimental.coroutines "enable"

[voddan]

The config above does not work

[voddan]

I think I need to correct the versions of kotlin plugin, kotlin stdlib, coroutines, coroutines core and ktor

[cy]

What error do you get?

[cy]

coroutines should be 0.30.2-eap13

[voddan]

It can't resolve any Ktor package

[cy]

You also need kotlinx repository

[voddan]

which one is it?

[voddan]

I read a migration guide somewhere, but the link to it is gone

[cy]

This is because all these packages are beta/alpha/RC so not published to jcenter/central

[cy]

at least this https://github.com/Kotlin/kotlinx.coroutines/blob/master/COMPATIBILITY.md#migration-to-100-version-with-kotlin-13

[voddan]

it works now!

[voddan]

plugins {
    id 'org.jetbrains.kotlin.jvm' version '1.3.0-rc-131'
    id 'application'
}

group 'kotlin.examples.ktor'
version '1.0-SNAPSHOT'

repositories {
    maven {     url '<http://dl.bintray.com/kotlin/kotlin-eap>' }
    mavenCentral()
    jcenter()
    maven { url "<https://dl.bintray.com/kotlin/ktor>" }
}

ext.ktor_version = '1.0.0-alpha-1'
ext.coroutines_version = '0.30.2-eap13'

dependencies {
    compile "org.jetbrains.kotlin:kotlin-stdlib-jdk8"
    compile "io.ktor:ktor-server-netty:$ktor_version"
    compile "ch.qos.logback:logback-classic:1.2.3"
}

sourceCompatibility = 1.8
compileKotlin { kotlinOptions.jvmTarget = "1.8" }
compileTestKotlin { kotlinOptions.jvmTarget = "1.8" }

[voddan]

Note I didn't need a repo or a kotlinx artifact for some reason

[voddan]

Thanks for the help!

[voddan]

In general, the current situation with versions of various libraries is a mess. I understand that it is temporally untill kotlin is 1.3, but if you could provide clear compatibility mappings for all JB packages, that would be greatly appreciated

I’m in the process of updating the IJ plugin and website generator + updating the documentation

[Deactivated User]

I have updated the generator website to support 1.0.0-alpha (the IJ plugin is submited but not published yet): https://ktor.io/quickstart/generator.html

There you can create a valid Gradle and Gradle with Kotlin DSL project for 1.0.0-alpha
