Hello. I am updating serialization to 1.1.0-RC, and using Kotlin 1.4.30-RC (latest available for Canary), but I get this error:

Could not find org.jetbrains.kotlin:kotlin-stdlib-common:1.4.30-270.
Required by:
    project :salonbiz-library > org.jetbrains.kotlinx:kotlinx-serialization-core:1.1.0-RC
    project :salonbiz-library > org.jetbrains.kotlinx:kotlinx-serialization-json:1.1.0-RC

Do I perhaps have to add an explicit dependency to stdlib, or something else going on?

[tylerwilson]

Yeah, that appeared to fix the gradle sync issue:

implementation("org.jetbrains.kotlin:kotlin-stdlib:$kotlinVersion")

added commonMain

I have that often. Usually fixed by reopening the project.

[tylerwilson]

Cool, thank you for the tip. And now I am getting some odd Kotlin.Result ClassCastException. 😞

[Marc Knaup]

Maybe that one?

[tylerwilson]

That could be it. I have a method that takes a callback reference which sends back a Result, like so:

fun updateToken(completion: (Result<String>) -> Unit) {

and when it is called it is saying:

java.lang.ClassCastException: java.lang.String cannot be cast to kotlin.Result

And this is in the release 1.4.30? uh-oh. I do this in many, many places.

Thank you for the link. I tried setting useIR to false, but no change. Back to 1.4.21-2 I go. Thanks again!
