kotlin - 执行org.jetbrains.kotlin.gradle.internal.KaptExecution Room数据库时发生故障

Question

我已经为这个错误苦苦挣扎了许多小时，并且能够追溯到第一次发生该错误时。将@Database批注添加到数据库类后，我立即收到一条错误消息，提示“执行org.jetbrains.kotlin.gradle.internal.KaptExecution时发生故障”，有人可以提出建议吗？为了完成这一点，我不得不退后几个小时的工作，这让我很伤脑筋。
GameDatabase.kt

package com.arcsoft.psncollection.data

import android.content.Context
import androidx.room.Database
import androidx.room.Room
import androidx.room.RoomDatabase

@Database(entities = [Game::class], version = 1, exportSchema = true)
abstract class GameDatabase: RoomDatabase() {
    abstract fun monsterDao(): GameDao

    companion object {
        @Volatile
        private var INSTANCE: GameDatabase? = null

        fun getDatabase(context: Context): GameDatabase {
            if (INSTANCE == null) {
                synchronized(this) {
                    INSTANCE = Room.databaseBuilder(
                        context.applicationContext,
                        GameDatabase::class.java,
                        "games.db"
                    ).build()
                }
            }
            return INSTANCE!!

    }

您是否尝试过在Debug模式下进行编译以获取更多信息？您可以通过以下方法来执行此操作:单击Android Studio右侧栏中的 Gradle ，然后单击 Tasks / other / compileDebugKotlin 。清理和重建项目大部分时间对我有帮助。
您的数据库类似乎还不错。。。将Room与Kotlin协程一起使用，对吗？所有@Query批注都在编译时进行了验证，因此可能是问题所在。我建议在您的Dao文件内的suspend中添加fun getAll()关键字，以便Room可以保证它将在后台线程上运行。
另外，我最近在Room中使用了协程，如果您想查看我的代码(在Github上)，可以使用link，这不是最好的示例，但是它可以以某种方式为您提供帮助。
