为什么是androidx。房间RoomDatabase未被识别?

我正在学习模块化,在我的一个模块中 androidx.room.* 不被认可。降级房间版本只对 @Database 注释。而且,模块似乎看不到 Room.roomKtx 实现,因为快速帮助建议将此实现添加到 build.gradle 我的 科特林版本 是 1.6.21

档案数据库。kt

import androidx.room.Database
import androidx.room.RoomDatabase
import com.example.modules.Gift
import com.example.modules.Profile

@Database(
    entities = [Profile::class, Gift::class],
    version = 1
)
abstract class ProfileDatabase: RoomDatabase() {
    abstract val profileDao: ProfileDao

    companion object {
        const val DATABASE_NAME = "profile_db"
    }
}

建筑gradle(:profileDatabase)

apply {
    from("$rootDir/library-build.gradle")
    plugin 'kotlin-kapt'
}

dependencies {
    implementation(project(':modules'))
    implementation Kotlinx.coroutinesCore

    implementation Room.runtime
    implementation Room.roomKtx
    kapt Room.compiler

}

房间kt

object Room {
    private const val roomVersion = "2.4.2"
    const val runtime = "androidx.room:room-runtime:$roomVersion"
    const val compiler = "androidx.room:room-compiler:$roomVersion"
    const val roomKtx = "androidx.room:room-ktx:$roomVersion"
}
