hi everyone,

I’m trying to upgrade a library from using alpha04 to alpha08 and I have added the following to the `build.gradle.kts`:

android {
  buildFeatures {
        compose = true
    }

    compileOptions {
        targetCompatibility = JavaVersion.VERSION_1_8
        sourceCompatibility = JavaVersion.VERSION_1_8
    }
    composeOptions {
        composeOptions.kotlinCompilerVersion = versionsProperties["version.kotlin"].toString()
        kotlinCompilerExtensionVersion = versionsProperties["version.androidx.ui"].toString()
    }
}
tasks.withType<org.jetbrains.kotlin.gradle.tasks.KotlinCompile> {
    kotlinOptions {
        jvmTarget = "1.8"
        freeCompilerArgs = listOf("-Xallow-jvm-ir-dependencies", "-Xskip-prerelease-check")
        useIR = true
    }
}

However, I’m still getting the following error message for several classes:

Class 'androidx.compose.ui.Modifier' is compiled by a new Kotlin compiler backend and cannot be loaded by the old compiler

I'm wondering if this might help: https://kotlinlang.slack.com/archives/CJLTWPH7S/p1597066702478100?thread_ts=1597030584.471000&cid=CJLTWPH7S

Not sure if it's because I just woke up but I can't see the difference? 😔
