Android的orm开源库也挺多的，但是个人项目使用的时候总有一些不满意的地方，稳定的库太复杂了，为了一丁点存储功能引入一个大的库显然不合适，小巧的要么bug多又不太稳定要么使用起来麻烦，在一些项目里面使用了一段时间ObjectBox之后，我把它引入到了一些新的项目，前阵子我想通过objectbrowser查看数据的时候，发现无法编译通过, gradle配置如下

ext.objectboxVersion = '2.3.4'
dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])

    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"

    releaseImplementation "io.objectbox:objectbox-kotlin:$objectboxVersion"
    kapt "io.objectbox:objectbox-processor:$objectboxVersion"

    debugImplementation "io.objectbox:objectbox-android-objectbrowser:$objectboxVersion"
}

结果运行的时候一直报错

Go to the documentation to learn how to Fix dependency resolution errors.

错误提示是有类重复引入，我就纳闷了，都没有引入多个，这问题是从哪冒出来的，不管是清理缓存还是各种exclude都不管用，鉴于之前这篇文章ANDROID工程出现FAILED TO RESOLVE: SUPPORT-FRAGMENT出现的问题，我又脑洞大开，各种操作尝试，最后把

//bottom of build.gradle
apply plugin: 'io.objectbox'

放到app模块gradle文件的最后一行就解决了，这样在adb forward tcp:8090 tcp:8090之后，就可以通过http://localhost:8090/index.html访问数据库了。
