What could this mean?

throwLinkageError("Function 'encodeToString' can not be called: No function found for symbol 'kotlinx.serialization.json/Json.encodeToString|encodeToString(0:0){0\xA7<kotlin.Any?>}[0]'");

I'm getting this when upgrading a Kotlin/JS project to Kotlin 2.1.20-RC.

[Robert Jaros]

I've traced the problem to the spring-dependency-management-plugin being applied to the project (it's a fullstack project with JS/WasmJs + JVM targets).

[Robert Jaros]

I've had problems with this plugin not long ago - it breaks incremental compilation for K/JS (see: https://youtrack.jetbrains.com/issue/KT-74378). Still I don't get how this JVM plugin can affect K/JS compilation in such ways?!

[Artem Kobzar]

This is a part of partial linkage. The error means that there is no more kotlinx.serialization.json/Json.encodeToString|encodeToString with the provided signature.
What kotlinx.serialization.json version do you use?

[Robert Jaros]

the latest - 1.8.0

[Artem Kobzar]

@sandwwraith is it something we know about?

[sandwwraith]

We've added encodeToString as a Json member, but the original extension wasn't removed — https://github.com/Kotlin/kotlinx.serialization/pull/2853/files

[sandwwraith]

So I'm not sure this is related. No other changes were made to this function

[Robert Jaros]

Everything works ok if I don't apply the spring dependency management plugin. So I think there is something wrong with the plugin or with the Kotlin compiler itself.

[Robert Jaros]

I would say the plugin somehow mixes up serialization versions used by the K/JS compiler?

[Robert Jaros]

I've managed to reproduce the issue with my github open source project.

[Robert Jaros]

Should I open an issue? Where?

[Artem Kobzar]

Could you please open it for Kotlin/JS?

[Robert Jaros]

Ok

[Robert Jaros]

I've managed to find a solution (a workaround?). I can add

extra["kotlin-serialization.version"] = libs.versions.kotlinx.serialization.get()

to my project to force 1.8.0 version for kotlinx.serialization (it seems the default for spring is 1.6.3).

[Robert Jaros]

But I would never guess this property can affect K/JS target.

[Robert Jaros]

I've updated the issue
