Я уже несколько дней сталкиваюсь с проблемой.Я разрабатываю приложение, используя Kotlin и библиотеку постоянства комнат.Моя база данных состоит из 4 объектов.Проблема в том, что всякий раз, когда я добавляю kapt "android.arch.persistence.room:compiler:$room_version" независимо от версии комнаты, я получаю следующие ошибки и предупреждения компиляции:

база данных приложений 

@Database(entities = [(recipesEntity::class), (chefEntity::class), (stepsEntity::class), (ingredientEntity::class)],
        version = 1, exportSchema = false)

abstract class appDatabase : RoomDatabase() {
    abstract fun appDao(): appDao
}

appDao 

@Dao
interface appDao {

    @Query("SELECT * from recipesEntity")
    fun getAll(): List<recipesEntity>

    @Insert(onConflict = OnConflictStrategy.REPLACE)
    fun insert(recipes: recipesEntity)

    @Insert(onConflict = OnConflictStrategy.REPLACE)

У меня была эта проблема, убедитесь, что расширение ваших файлов правильное, например, у меня был файл с именем AccreditationLogo, а не AccreditationLogo.kt.Казалось, это странно мешает компилятору.
