Android 由于NoClassDefFoundError，检测测试失败

从今天起，我就在调试模式下对kotlin应用程序进行多重索引，因为库迫使我这样做。我的问题是我的UI测试不再工作了。我也在缩小我的apk

我得到以下错误：

是否有人在使用OkHttp MockWebServer时收到此错误？或者别的什么。也许我错过了一些前进的规则

我的应用程序/build.gradle文件：

android {
    defaultConfig {
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        debug {    
            debuggable true
            minifyEnabled true
            dexOptions {
                multiDexEnabled true
            }
    }
}

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib:1.1.60"

    androidTestImplementation "com.squareup.okhttp3:mockwebserver:3.8.1"
    androidTestImplementation "com.android.support.test:runner:1.0.1"
    androidTestImplementation "com.android.support.test:rules:1.0.1"
}

如果我的方法是正确的，我将非常感谢任何帮助和/或讨论。

我今天可能会遇到同样的错误。我们还有一个多索引应用程序。你是怎么解决的？
