Realm Android javassist.NotFoundException:io.realm.com_example_realmtest_data_SomethingRealmProxyInterface

问题描述

我是android领域的新手，我从简单的kotlin-project开始，只有一个只有一个字段的实体.

I was completely new to realm in android, and I started from simple kotlin-project with only one entity which had only one field.

open class Something : RealmObject() {
   @PrimaryKey 
   var id: Long = 0
}

我在Application类中初始化了Realm:

I initialized Realm in my Application class:

class RealmApp : Application() {

    override fun onCreate() {
        super.onCreate()

        Realm.init(this)
        val config = RealmConfiguration.Builder().build()
        Realm.setDefaultConfiguration(config)
    }
}

当然，我添加了领域插件:

And, of course I added realm plugin:

//Project level
dependencies {
    ...
    classpath "io.realm:realm-gradle-plugin:5.9.0"
}

//Module level
apply plugin: 'realm-android'

一个简单的项目，但是每次我尝试编译它时，都会出现异常:

Simple project, but every time I tried to compile it, exception appeared:

Caused by: javassist.NotFoundException: io.realm.com_example_realmtest_data_SomethingRealmProxyInterface

我整天都在搜索以解决此问题，但是什么也没找到.

I searched for whole day to solve this problem, but didn't find anything.

推荐答案

因此，事实证明，我只需要在模块级别 build.gradle 中使用apply plugin: 'kotlin-kapt'.看起来Kotlin需要生成这些类.由于这个愚蠢的错误，我浪费了很多时间，所以我希望这个答案能对遇到类似错误的人们有所帮助.

So it turned out that I simply needed apply plugin: 'kotlin-kapt' in my module level build.gradle. Looks like Kotlin need that to generate these classes. I lost a lot of time because of that silly mistake, so I hope that this answer will help people that are getting similar error.

编辑

并且正如注释中提到的 musoof 一样，apply plugin: 'kotlin-kapt'的顺序很重要.您必须将其包括在apply plugin: 'realm-android'之前.否则，您仍然会收到相同的错误.

And as musoof mentioned in the comments, order of apply plugin: 'kotlin-kapt' matters. You have to include it before apply plugin: 'realm-android'. Otherwise you will still get the same error.
