What is the new way to have convention plugin for common extension in a jetpack compose project?

I have used the Convention plugin for **`ApplicationExtension`** and **`LibraryExtension`**, but the new version of **Android Gradle Plugin(AGP)** seems to be unable to support some extensions like the **Common Extension**.
How can I fix this problem in the AGP 9.0.0?

class FlavorsConventionPlugin : Plugin<Project> { override fun apply(project: Project) { project.plugins.withId("com.android.library") { project.extensions.configure<LibraryExtension> { configureFlavors(this, project) } } project.plugins.withId("com.android.application") { project.extensions.configure<ApplicationExtension> { configureFlavors(this, project) } } } }

And this is the Flavor information file and the configureFlavors function

enum class Dimension { TEST } @Suppress("EnumEntryName") enum class Flavor( val dimension: Dimension, val applicationIdSuffix: String? = null, val versionNameSuffix: String? = null ) { dev( dimension = Dimension.TEST, applicationIdSuffix = ".dev", versionNameSuffix = "-dev" ), uat( dimension = Dimension.TEST, applicationIdSuffix = ".uat", versionNameSuffix = "-uat" ), prod(dimension = Dimension.TEST), } fun configureFlavors( commonExtension: CommonExtension<*, *, *, *, *, *>, project: Project, flavorConfigurationBlock: ProductFlavor.(flavor: Flavor) -> Unit = {}, ) { val props = loadFlavorProperties(project) commonExtension.apply { Dimension.entries.forEach { flavorDimension -> flavorDimensions += flavorDimension.name } productFlavors { Flavor.entries.forEach { flavor -> register(flavor.name) { dimension = flavor.dimension.name val walletUrl = props["$flavor.WALLET_BASE_URL"] as? String val authUrl = props["$flavor.AUTH_BASE_URL"] as? String if (this@apply is ApplicationExtension && this is ApplicationProductFlavor) { if (flavor.applicationIdSuffix != null) applicationIdSuffix = flavor.applicationIdSuffix if (flavor.versionNameSuffix != null) versionNameSuffix = flavor.versionNameSuffix } buildConfigField("String", "WALLET_BASE_URL", "\"$walletUrl\"") buildConfigField("String", "AUTH_BASE_URL", "\"$authUrl\"") buildFeatures.buildConfig = true flavorConfigurationBlock(this, flavor) } } } } } private fun loadFlavorProperties(project: Project): Properties { val props = Properties() val file = project.rootProject.file("flavors.properties") if (file.exists()) { props.load(file.inputStream()) } else { throw GradleException("Missing flavors.properties file at project root.") } return props }
