错误任务“：app：kaptdebugkotlin”的MyApplication执行失败

Question

我有一个错误在我的应用程序，每次我看到我建立的项目它出现，我认为这是与房间的关系，但我不能解决它

日志：

MyApplication.java

package com.example.pokedex;

import java.lang.System;

d2 = {"Lcom/example/pokedex/MyApplication;", "Landroid/app/Application;", "()V", "dataBase", 
"LAppDataBase;", "getDataBase", "()LAppDataBase;", "dataBase$delegate", "Lkotlin/Lazy;", 
"repository", "Lcom/example/pokedex/repository/PokedexRepository;", "getRepository", " 
()Lcom/example/pokedex/repository/PokedexRepository;", "repository$delegate", "app_debug"})
public class MyApplication extends android.app.Application {
    @org.jetbrains.annotations.NotNull()
    private final kotlin.Lazy dataBase$delegate = null;
    @org.jetbrains.annotations.NotNull()
    private final kotlin.Lazy repository$delegate = null;

    @org.jetbrains.annotations.NotNull()
    public final AppDataBase getDataBase() {   //  line where the error is being shown in the log
        return null;
    }

    @org.jetbrains.annotations.NotNull()
    public final com.example.pokedex.repository.PokedexRepository getRepository() {
        return null;
    }

    public MyApplication() {
        super();
    }
}

类AppDatabase

@Database(entities = [PokemonItem::class], version = 1, exportSchema = false)
abstract class AppDataBase: RoomDatabase() {
abstract fun pokemonDAO(): PokemonDAO

companion object {
    @Volatile
    private var INSTANCE: AppDataBase? = null
    fun getDataBase(context: Context): AppDataBase {
        return INSTANCE ?: synchronized(this) {
            val instance = Room.databaseBuilder(
                context.applicationContext,
                AppDataBase::class.java,
                "pokemon-db"
            )
                .build()
            INSTANCE = instance
            instance
        }
    }
   }
 }

这个错误是在我使用AppDatabase进行数据持久化时开始发生的，我以为问题已经出现了，但从我看到的情况来看，我无法通过它的版本来修复它
