Unable to resolve dependency for :Could not resolve org.jetbrains.kotlinx:kotlinx-serialization-runtime-native:0.8.1-rc13

Question

I am getting a gradle build error for unresolved dependencies in a Kotlin/Native sample project.

Failed to resolve: org.jetbrains.kotlinx:kotlinx-serialization-runtime-native:0.8.1-rc13

my build.gradle (common module) looks like

apply plugin: 'kotlin-platform-common'
apply plugin: 'kotlinx-serialization'

task clean(type: Delete) {
    delete rootProject.buildDir
}

settings.gradle::

include ':android', ':common', ':myapplication'
enableFeaturePreview('GRADLE_METADATA')

What are the correct versions and repositories that I can use to be able to use serialization?

Setup you've attached is kinda strange, because you're applying Kotlin/Native's 'konan' plugin to the same module as 'kotlin-platform-common' plugin. First of all, 'konan' is deprecated and replaced with 'kotlin-platform-native'. Secondly, these plugins should be applied to different gradle modules, see kotlin multiplatform reference.

Regarding serialization, it now comes in two flavours: One, for Kotlin 1.2 has version numbers 0.6.x (0.6.2 for 1.2.70) and does not support Kotlin/Native; only separate json parser is provided instead. Second flavour, for Kotlin 1.3 is under development phase and has number 0.8.x-rc13 (latest one is 0.8.1-rc13 for Kotlin/Native 0.9.2) and it does contain K/N support in a separate artifact with coordinates "kotlinx-serialization-runtime-native". Serialization docs for Kotlin 1.3 preview reveal more information: https://github.com/Kotlin/kotlinx.serialization/blob/master/docs/eap13.md .

There is also a dedicated example of setup which contains a ready-to-use stub of multiplatform project with serialization. Branch native_preview uses aforementioned Kotlin 1.3-rc, K/N 0.9.2 and serialization 0.8.1.

I need a module with expected classes that I will be "actual" implementing in the platform-modules. I need this module to compile both for ios and android as it will contain common logic for all. Hence, both the konan and kotlin-platform-common plugins – Nishita Oct 03 '18 at 10:03
I am still getting the same error for kotlin_version = '1.3.0-rc-57' and serialization_version = '0.8.1-rc13' and kotlin-native:0.9.2 – Nishita Oct 03 '18 at 10:32
You have to apply 'kotlin-platform-common' to common module with expected classes and logic, and 'kotlin-platform-native' to ios module with actual classes. apply plugin: 'kotlinx-serialziation' won't work with 'konan', it works only with 'kotlin-platform-native' and 'kotlin-mutliplatform'. 'konan' also uses deprecated model for resolving dependencies; that's probably why you have them unresolved. – sandwwraith Oct 04 '18 at 11:22
Also, make sure that you have 'enableFeaturePreview('GRADLE_METADATA')' in your 'settings.gradle', otherwise dependencies won't work. – sandwwraith Oct 04 '18 at 11:23
Why are you adding native runtime library to the common module? – sandwwraith Oct 14 '18 at 19:53
Doesn't help even if I add runtime-common or remove that dependency all together. Have tried them both. – Nishita Oct 22 '18 at 09:44
