Hi all I have an issue trying to add Compose to my project When building project i get this error:

e: androidx.compose.compiler.plugins.kotlin.IncompatibleComposeRuntimeVersionException: You are using an outdated version of Compose Runtime that is not compatible with the version of the Compose Compiler plugin you have installed. The compose compiler plugin you are using (version 0.1.0-dev16) expects a minimum runtime version of 0.1.0-dev16.

But i specify in build.gradle for 2 modules (feature module when i want to use compose and app module) latest version of compose:

android {

    buildFeatures {
        compose true
    }

    composeOptions {
        kotlinCompilerVersion '1.4.0'
        kotlinCompilerExtensionVersion '1.0.0-alpha01'
    }

    kotlinOptions {
        jvmTarget = jvmTargetVer
        useIR = true
    }
}

I use gradle plugin version 4.2.0-alpha08:

classpath 'com.android.tools.build:gradle:4.2.0-alpha08'

and gradle version 6.6:

distributionUrl=https\://services.gradle.org/distributions/gradle-6.6-all.zip

and kotlin version 1.4.0:

classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.4.0"

Could anyone help me please? What i'm doing wrong?

Try doing a global search for

dev16

and replace that with

alpha01

. It seems likely you've got a lingering reference to

dev16

in one of your gradle files.

i tried to do this, but i am sure that i do not specify version

dev16

nowhere explicitly maybe it is used somewhere implicitly

What version of Android Studio do you use?

4.2 Canary 8

invalidate caches?

Have you set the compiler args? e.g:

tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile).configureEach {
    kotlinOptions {
        jvmTarget = "1.8"
        freeCompilerArgs += ["-Xallow-jvm-ir-dependencies", "-Xskip-prerelease-check"]
        // Opt-in to experimental compose APIs
        freeCompilerArgs += '-Xopt-in=kotlin.RequiresOptIn'
    }
}

tried to add the snippet above, then clean the project, invalidate caches and restart, and then rebuild project but have the same issue can it be related to multimodule project? because for now, a have added compose only to two modules (feature module and app module). maybe i should add compose to all the modules?
