更新到 SDK 31 后，Room 数据库停止工作：COuld Not find @Entity 导致 Room 无法构建

Question

这是我在尝试构建项目时看到的。除了 Android 强制我在 Manifest 中更改的内容之外，我没有更改任何内容，我不知道此后该去哪里。

道

@Dao
interface SubscriberDAO {
@Insert
suspend fun insertSubscriber(subscriber: Subscriber): Long

@Update
suspend fun updateSubscriber(subscriber: Subscriber): Int

@Delete
suspend fun deleteSubscriber(subscriber: Subscriber): Int

@Query("DELETE FROM subscriber_data_table")
suspend fun deleteAll(): Int

@Query("SELECT * FROM subscriber_data_table")
fun getAllSubscribers(): LiveData<List<Subscriber>>

}

怎么了？我尝试将 TargetSdk 改回 30，但仍然无效

Gradle

apply plugin: 'kotlin-android'
apply plugin: 'kotlin-kapt'

    compileSdkVersion 31

Answer 1

我最后在 reddit 上询问并被告知回滚 gradle 依赖项。 classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" 从 ext.kotlin_version = "1.6.0" 到 ext.kotlin_version = "1.5.31" 我不确定我会称之为前进的道路，但我可以继续我的项目，所以我称之为一个，直到真正的答案出现

更新到 SDK 31 后，Room 数据库停止工作：COuld Not find @Entity 导致 Room 无法构建

After update to SDK 31 Room Database stopped working: COuld Not find @Entity which causes Room to not Build
