This version (1.1.1) of the Compose Compiler requires Kotlin version 1.6.10 but you appear to be using Kotlin version 1.5.31 - android-studio

Question

I'm using the latest Android Studio and I'm able to build and run my app fine with compose_version set to 1.0.5. However, I'd like to use the latest stable compose version 1.1.1.
I try to simply update the project build.gradle so it contains the following pointing to the desired compose version and the corresponding compatible kotlin version. These values are referenced in the app's build.gradle.
buildscript {
ext {
compose_version = '1.1.1'
kotlin_version = '1.6.10'
}
And in Android Studio, I go to Tools > Kotlin > Configure Kotlin Plugin Updates and download the latest Kotlin plugin (Early Access).
If I open Tools > Kotlin > Kotlin REPL, I see Welcome to Kotlin version 1.7.0-RC2-release-258 (JRE 11.0.12+0-b1504.28-7817840).
Now, I try to Rebuild Project.
I get the error:
This version (1.1.1) of the Compose Compiler requires Kotlin version 1.6.10 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!).
I don't wish to suppressKotlinVersionCompatibilityCheck given the warning, but I even tried that option and got other build errors.
Why is Kotlin version 1.5.31 being used? Shouldn't updating the Kotlin plugin have gotten Android Studio to switch to a more recent Kotlin version (as suggested by the Kotlin REPL message)? How can I make it such that Kotlin 1.6.10 is used and I stop getting the error?

Answer 1

Got the same error when using Compose 1.1.1. and Kotlin 1.7.0.
Task :app:compileDebugKotlin FAILED
e: This version (1.1.1) of the Compose Compiler requires
Kotlin version 1.6.10 but you appear to be using Kotlin version 1.7.0
which is not known to be compatible. Please fix your configuration (or suppressKotlinVersionCompatibilityCheck but don't say I didn't warn you!).
Changed the below block in my build.gradle (app module)
composeOptions {
kotlinCompilerExtensionVersion 1.2.0
}
This is my plugins block in build.gradle (project):
plugins {
id 'com.android.application' version '7.2.1' apply false
id 'com.android.library' version '7.2.1' apply false
id 'org.jetbrains.kotlin.android' version '1.6.21' apply false
id 'org.jetbrains.kotlin.jvm' version '1.7.0' apply false
}
This Android developers page helped with picking the compatible versions :-

Don't forget to sync and rebuild.

Compose uses the kotlin compiler defined in your buildscript block:
buildscript {
ext.kotlin_version = '1.6.10'
//....
dependencies {
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
}
If you are using the plugins block in settings.gradle or build.gradle:
pluginManagement {
plugins {
id 'org.jetbrains.kotlin.android' version '1.6.10'
}
}

Using this help me.
build.gradle (:app)
composeOptions {
kotlinCompilerExtensionVersion = "1.2.0-beta03"
}

Answer 4

There are 3 things you need to ensure are in sync(compatible with the other) for kotlin to work properly.
1)compose_ui_version='1.2.1' of buildscript in build.gradle(project)
2)plugin 'org.jetbrains.kotlin.android' version '1.7.10' in build.gradle(project)
3)kotlinCompilerExtensionVersion '1.3.1' in composeOptions in build.gradle(app)
To get the latest version of compose compiler and its corresponding kotlin version check here.

Answer 5

for me what I had to edit is to locate build graddle(Project):
first load compose_version to see the latest stable compose_version.
buildscript {
ext {
//2. change here to the latest stable (compose_version) that you got in step 1
compose_version = '1.3.0'
}
repositories {
google()
mavenCentral()
}
dependencies {
//when you run you app, The next error will tell you the version of Kotlin that the latest compose_version needs, edit as below to the version required in the error
classpath 'org.jetbrains.kotlin:kotlin-gradle-plugin:1.7.10'
}

Answer 6

buildscript {
dependencies {
classpath 'com.android.tools.build:gradle:7.1.3'
}
}
plugins {
id 'org.jetbrains.kotlin.android' version '1.6.10' apply false
}
and build.gradle(Module)
composeOptions {
kotlinCompilerExtensionVersion '1.1.1'
}

Answer 7

Go to your project level build.gradle file
There in the plugin section below mentioned 2 libraries has to be in the same version to remove this error:
{
...
id 'org.jetbrains.kotlin.android' version '1.6.10' apply false
id 'org.jetbrains.kotlin.jvm' version '1.6.10' apply false
}
If required, change:
compileSdk 33
&
targetSdk to 33
. (inside app level build.gradle file).
Now sync the project & reload the priview. It will work fine.
