Jetpack Compose on Kotlin 1.5.0

Update: androidx.compose.compiler:compiler:1.0.0-beta08 is released (June 2, 2021).

From this version, the expected version of Kotlin is 1.5.10.

dependencies {    implementation "androidx.compose.compiler:compiler:1.0.0-beta08"}android {    buildFeatures {        compose true    }    composeOptions {        kotlinCompilerVersion "1.5.10"        kotlinCompilerExtensionVersion "1.0.0-beta08"    }    kotlinOptions {        jvmTarget = "1.8"    }}

Compose compiler 1.0.0-beta07 is not supporting Kotlin 1.5.0 yet.

And I found that the changes of supporting Kotlin 1.5.0 have merged, but not released yet.

For this moment, in my opinion, you should use 1.4.3 and wait for the next version (1.0.0:beta08 or 1.0.0)

• In the build.gradle file (project):

  Change classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.5.0"

  To classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.5.21"

• In the build.gradle file (app):

  composeOptions {            kotlinCompilerExtensionVersion compose_version            kotlinCompilerVersion kotlin_version        }

  compose_version will be 1.0.1

  kotlin_version will be 1.5.21

This version (1.0.0-beta07) of the Compose Compiler requires Kotlin version 1.4.32 but you appear to be using Kotlin version 1.5.0 which is not known to be compatible. Please fix your configuration (or suppressKotlinVersionCompatibilityCheck but don't say I didn't warn you!)
