java - "Object"不是这个 Realm 的架构的一部分

Question

当我调用 realm.where(MessageEventModel::class.java).findAll()

它抛出异常:这是错误

java.lang.IllegalArgumentException: MessageEventModel is not part of the schema for this Realm
                                                                          at io.realm.internal.modules.CompositeMediator.getMediator(CompositeMediator.java:172)
                                                                     at io.realm.internal.modules.CompositeMediator.getTableName(CompositeMediator.java:90)

这是我的应用程序类

class MyApp : Application() {

override fun onCreate() {
    super.onCreate()
    Realm.init(this)
    val realmConfiguration = RealmConfiguration.Builder()
            .deleteRealmIfMigrationNeeded()
            .name("my_db")
            .build()
    Realm.setDefaultConfiguration(realmConfiguration)
}
}

这是我的 Realm 模型

class MessageEventModel : RealmObject{
  constructor()
  var message = ""
  constructor(message: String) : this(){
    this.message = message
  }
}

这是我尝试检索模型的地方

class AwesomeChatFragment : Fragment() {

private val realm: Realm by lazy { Realm.getDefaultInstance() }
private var notifications: RealmResults<MessageEventModel>? = null

override fun onCreateView(inflater: LayoutInflater?, container: ViewGroup?, savedInstanceState: Bundle?): View? {
    val view = inflater?.inflate(R.layout.activity_awesome_chat, container, false)
    notifications = realm.where(MessageEventModel::class.java).findAll()
    return view
}
}

渐变配置:

apply plugin: 'com.android.application'
apply plugin: 'realm-android'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'


buildscript {
    ext.kotlin_version = '1.1.1'
    repositories {
        jcenter()
    }
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.android.tools.build:gradle:2.3.0'
        classpath 'com.google.gms:google-services:3.0.0'
        classpath "io.realm:realm-gradle-plugin:3.0.0"
    }
}

我尝试了所有我能在堆栈上找到的东西:清理构建、重建项目、启用注释处理器、重新安装 apk、使缓存无效/重新启动

gradle 文件中的问题。仅应用插件的排序规则的问题，感谢@EpicPandaForce 的评论，问题已解决，我正在写答案，以帮助其他人，如果他们错过了评论的答案来自@EpicPandaForce

我改变了顺序

apply plugin: 'com.android.application'
apply plugin: 'realm-android'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'

到

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
apply plugin: 'realm-android'

就这样，现在一切正常
