由于我未知的原因,将@Query添加到我的房间后,我的应用将无法构建。
我通过逐步执行所有操作来弄清楚它是@Query,最终在我添加@Query函数时出现了错误。
我得到的错误是:
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:kaptDebugKotlin'.
> A failure occurred while executing org.jetbrains.kotlin.gradle.internal.KaptExecution

这是我的代码:MainDatabase.kt
import android.content.Context
import androidx.room.Database
import androidx.room.Room
import androidx.room.RoomDatabase
import my.test.movieexpert.localdatasource.dao.PopularMovieDao
import my.test.movieexpert.profilescreen.model.PopularMovie
@Database(entities = [PopularMovie::class], version = 1, exportSchema = false)
abstract class MainDatabase : RoomDatabase() {
abstract fun popularMovieDao(): PopularMovieDao
companion object {
@Volatile
private var Instance: MainDatabase? = null
fun getInstance(context: Context): MainDatabase {
val tempInstance = Instance
if (tempInstance != null) {
return tempInstance
}
synchronized(this) {
val instance = Room.databaseBuilder(
context.applicationContext,
MainDatabase::class.java,
"main_database"
).build()
Instance = instance
return instance
}
}
}
}
PopularMovieDao.kt =>每当我取消注释任何@Query函数时,我的应用程序都无法构建import androidx.room.Dao
import androidx.room.Insert
import androidx.room.OnConflictStrategy
import androidx.room.Query
@Dao
interface PopularMovieDao {
@Insert(onConflict = OnConflictStrategy.REPLACE)
suspend fun addMovies(listOfMovies: List<PopularMovie>)
// @Query("DELETE FROM PopularMovie")
// suspend fun clearTable()
// @Query("SELECT * FROM PopularMovie")
// suspend fun getMovies(): List<PopularMovie>
}
PopularMovie.ktimport androidx.room.Entity
import androidx.room.PrimaryKey
import com.squareup.moshi.Json
@Entity
data class PopularMovie(
@field:Json(name = "id") val id: Int,
@field:Json(name = "title") val title: String,
@field:Json(name = "overview") val overview: String,
@field:Json(name = "release_date") val release_date: String,
@field:Json(name = "poster_path") val poster_path: String,
@field:Json(name = "vote_average") val vote_average: String
) {
@PrimaryKey(autoGenerate = true)
var rowId: Int = 0
}
最佳答案
找到了问题。
在我的应用程序build.gradle中,我具有以下内容:
configurations.all() {
resolutionStrategy.force "org.antlr:antlr4-runtime:4.5.3"
resolutionStrategy.force "org.antlr:antlr4-tool:4.5.3"
}
过去,我将其用于DataBinding和Room之间的兼容性错误,并且不再需要它。
