i updated my idea plugin to 1.4.0-rc and now its complaining that my kotlinx.serialization core is too old. I’ll just go back to the stable plugin for now. Probably a good idea to not update the plugin until the rc release cycle is complete.

Which version of Kotlin was your project using?

M3. but i think the serialization problem is not related to m3.

RC release cycle is complete now. You can find the compatible versions here. It’s likely you’ll need to perform some migration to the new version of

kotlinx.serialization

, though, since it made a step on its straight way to the stable (1.0) release and has introduced some breaking changes.

@Liliia coming from

1.4-M1

it still looks like some artifacts are missing, like:

org.jetbrains.kotlinx:kotlinx-coroutines-core-common:1.3.8-1.4.0-rc
org.jetbrains.kotlinx:kotlinx-serialization-runtime-common:1.0-M1-1.4.0-rc
org.jetbrains.kotlinx:kotlinx-serialization-protobuf-common:1.0-M1-1.4.0-rc

i think you don’t need those anymore, for example just use this in common:

implementation("org.jetbrains.kotlinx:kotlinx-serialization-runtime:$serializationVersion")

@Oliver.O, Christoph is completely right.

@christophsturm @Liliia Thanks, I'll have a look!
