Using compose in a multiplatform project , getting the error :

e: This version (1.1.0-alpha01) of the Compose Compiler requires Kotlin version 1.5.21 but you appear to be using Kotlin version 1.5.31 which is not known to be compatible. Please fix your configuration (or suppressKotlinVersionCompatibilityCheck but don't say I didn't warn you!).

You need to use later version of Compose that works with 1.5.31

[John O'Reilly]

e.g. 1.0.4 or 1.1.0-alpha06

[Waqas Tahir]

org.jetbrains.compose.runtimeruntime1.0.4
Not found

[Waqas Tahir]

This is a multiplatform project so the dependencies are from jetbrains

[John O'Reilly]

is this jetpack compose or compose for desktop you're using?

[Waqas Tahir]

Compose multiplatform

[Waqas Tahir]

I updated my kotlin plugin to 1.5.31 and then started getting this error , tried downgrading kotlin Gradle plugin to 1.5.21 but it didn't work

[John O'Reilly]

what version of compose for desktop/web etc are you using?

[Waqas Tahir]

It comes from the jetbrains plugin for compose
Which is currently providing 1.0.0-alpha3

[John O'Reilly]

ok, that doesn't work with Kotlin 1.5.31.....try 1.0.0-alpha4-build398

[Waqas Tahir]

I Replaced the dependencies like this , but I'm still getting the error that compose compilers requires kotlin version 1.5.21

[Waqas Tahir]

I think I need to change the compiler version for compose , How can I do that in a compose multiplatform project !

[John O'Reilly]

Might be worth comparing to some of the samples at https://github.com/JetBrains/compose-jb/tree/master/examples

[John O'Reilly]

I see at least some of them are using Kotlin 1.5.31

[Waqas Tahir]

Should I downgrade to 1.5.21 , but I deleted the folder inside plugins directory and replaced it with the downloaded plugin from marketplace and restarted intellij and still got this error

[Waqas Tahir]

I tried downgrading it didn't work

[John O'Reilly]

I'd recommend perhaps starting with one of the samples linked to above

[Oliver.O]

These versions worked for me:

plugin.org.jetbrains.compose=1.0.0-alpha4-build362
version.kotlin=1.5.31
