How can I use Kotlin 1.4.21?

`e: This version (1.0.0-alpha09) of the Compose Compiler requires Kotlin version 1.4.20 but you appear to be using Kotlin version 1.4.21 which is not known to be compatible. Please fix your configuration (or suppressKotlinVersionCompatibilityCheck but don't say I didn't warn you!).`

You have to wait for Compose to support 1.4.21. I believe there’s a CL open for that right now, so probably in the next release or two

Thank you.

That CL was (https://android-review.googlesource.com/c/platform/frameworks/support/+/1521081) and got merged a few hours ago.

I suppose alpha09 is not released yet

[Kyant]

Yeah, but it may be a snapshot

In general you can pass the plugin configuration as part of Kotlin compile task if you really want to use 1.4.21

withType<KotlinCompile>().configureEach {
        kotlinOptions {
            freeCompilerArgs += listOf(
                "-progressive",
                "-Xjsr305=strict",
                "-P",
              "plugin:androidx.compose.compiler.plugins.kotlin:suppressKotlinVersionCompatibilityCheck=true"
            )
        }
    }

[Kyant]

But it says Source file or directory not found: plugin:androidx.compose.compiler.plugins.kotlin:suppressKotlinVersionCompatibilityCheck=true

[Kyant]

I'm using Compose for Desktop

[suresh]

@Kyant you need to pass "-P" also

[Kyant]

I have added it, gradle could synced, but still couldn't compile.

[suresh]

kotlin("jvm") version "1.4.21"
id("org.jetbrains.compose") version "0.3.0-build134"

It's working for me. I am using these deps. Are you using multiplatform?

[Kyant]

Yes
