Jetpack Compose on Kotlin 1.5.0

Question

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:

Answer 1

Update:

Thanks @Samuel Luís for finding a Compose to Kotlin compatibility table https://developer.android.com/jetpack/androidx/releases/compose-kotlin

---

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)

Answer 2

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.

Answer 3

• 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
