Jetpack Compose on Kotlin 1.5.0

I've updated to Kotlin 1.5 last week, and after yesterday having seen the intention of Google to make Jetpack Compose the preferred option for designing UIs, I wanted to do some testing.

The issue is that having my project updated to Kotlin 1.5, when trying to build the project I get the following error:

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!).

Is Kotlin 1.5 incompatible with Jetpack Compose? After googling the issue I found the 1.5.0-M2 release, which mentions Jetpack Compose, but not in an "incompatible" manner.

Do you have any answer to this? Should I use suppressKotlinVersionCompatibilityCheck? In that case, may I add it directly to android.kotlinOptions in the module's build.gradle file?

Thanks in advance.

Edit 1: I've found that I should add suppressKotlinVersionCompatibilityCheck as a builder arg:

android {
    ...
    kotlinOptions {
        ...
        freeCompilerArgs += [            "-P","plugin:androidx.compose.compiler.plugins.kotlin:suppressKotlinVersionCompatibilityCheck=true"        ]
        ...
    }
    ...
}

But it's still not compiling, I get this error from the compiler:

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.

https://android-review.googlesource.com/c/platform/frameworks/support/+/1651538

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)

This is what I did with latest compose version as until I write today.

compose_version = '1.2.0-alpha01'

1) Delete following line if exists you do not need it:

2) Update your Kotlin version with final version if needed how to do this -> click this link

3) Finally in build.gradle (:project) update compose version:

ext {
    compose_version = '1.2.0-alpha01'
}

And gradle plugin:

classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.6.10"

Now you should not have any warnings with latest version.

• 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

[update] compose_version = '1.0.0' is now stable for Kotlin 1.5.10

buildscript {
    ext {
        compose_version = '1.0.0'
    }
    repositories {
        google()
        mavenCentral()
    }
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.5.10"
    }
}

>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!)

> this version (1.0.0-beta08) of the Compose Compiler requires Kotlin version 1.5.10 but you appear to be using Kotlin version 1.4.31 which is not known to be compatible. Please fix your configuration (or suppressKotlinVersionCompatibilityCheck but don’t say I didn’t warn you!).

• The version 1.0.0-beta07 requires Kotlin 1.4.32

• The version 1.0.0-beta08 requires Kotlin 1.5.10

My problem fixed by downgrading Kotlin from 1.5.20 to 1.5.10, and adding kotlinCompilerVersion "1.5.10" to composeOptions in build.gradle file. like this:

composeOptions {
    kotlinCompilerVersion "1.5.10"
    kotlinCompilerExtensionVersion '1.0.0-rc01'
}

Check out this same question here https://stackoverflow.com/q/68690667/15880865

As of Compose 1.0.1, and Studio BumbleBee latest update (as of now), the required version of Kotlin required by compose is 1.5.10, however the Bumblebee update does not contain the kotlin version declaration even in the buildScript block. Now, you must change the declared dependency in the settings.gradle file, which is also where the studio picks it up from. Now, please note that even if you declared the correct version in the buildScript block in the project level build file, the project won't compile because studio will still fetch the version from the same place.

Also, if you are having a hard time finding out which version is required by the respective version of Compose, you can make the project, and when it fails, there's an option to run with scan to see full log output, which exposes the same. Alternatively, you could just edit it in the settings make it the default, whatever.

I had this problem when trying to migrate the old project to compose. For me, the solution was to create a compose activity. This can be done by hand or you can create an empty compose activity from the gallery.

i get the error like this

> e: This version (1.0.0) of the Compose Compiler requires Kotlin > version 1.5.10 but you appear to be using Kotlin version 1.5.20 which > is not known to be compatible. Please fix your configuration (or > suppressKotlinVersionCompatibilityCheck but don't say I didn't warn > you!).

and then I open the build.gradle(project) and change

classpath 'org.jetbrains.kotlin:kotlin-gradle-plugin:1.5.20'          

to this

classpath 'org.jetbrains.kotlin:kotlin-gradle-plugin:1.5.10' 

dont forget to sync and run the project. hope this work in you too!

Faced this problem when adding a new module. The fix was adding the following to the new module:

buildFeatures {
  compose true
}

composeOptions {
  kotlinCompilerExtensionVersion compose_version
}

1.0.0-beta07 seems to be what it picks when no version is selected.

Faced this issue while updating Kotlin version from 1.6.10 to 1.6.20

And fixed it update compose_version from 1.1.1 to 1.2.0-alpha08

For me modifying the project level build.gradle file with the required version of kotlin (which is mentioned in the error message) fixed the issue.

Eg: My error message read:

This version (1.1.1) of the Compose Compiler requires Kotlin version 1.6.10 but you appear to be using Kotlin version 1.5.21 which is not known to be compatible. Please fix your configuration

So I modified the kotlin version to 1.6.10 like below:

classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.6.10"

And my problem got solved

Make all of (upper of this page) https://stackoverflow.com/a/69508800/13432944

And mainly see this lines

composeOptions {
    kotlinCompilerExtensionVersion "1.0.4"
}
