原因：java.lang.RuntimeException：com.android.builder.dexing.DexArchiveMergerException：合并 dex 档案时出错：

Question

我无法构建发布 APK。每次我得到 DexMergerException。 这是我的 build.gradles：

我正在使用 MVVM 结构。我有核心（核心的包名称与我的应用程序包相同）有我的库，我只在其中编写视图模型、模型和网络层。

我遇到的错误：

下面是我的核心 build.gradle，我还为所有 lib 更新了相同的版本。

核心 build.gradle：

    defaultConfig {
        minSdkVersion 21
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

    }

    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }

    dataBinding {
        enabled = true
    }
    repositories {
        flatDir {
            dirs 'libs'
        }
        jcenter()
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    compileOnly 'com.wowza.gocoder.sdk.android:com.wowza.gocoder.sdk:1.0b7@aar'
//    compile 'android.arch.lifecycle:extensions:1.1.1'
    implementation 'com.google.dagger:dagger:2.11'
    api('com.squareup.retrofit2:retrofit:2.1.0') {
        exclude module: 'okhttp'
    }
    api 'com.google.code.gson:gson:2.8.1'

    compileOnly project(':com.wowza.gocoder.sdk')

    //Library for setting fonts

    implementation 'com.android.support:multidex:1.0.3'

}

我尝试了很多次，但我无法理解这个问题背后的原因。

Answer 1

我今天也发生了同样的事情，这就是解决问题的方法：

找到com.google.android.gms:play-services的所有依赖。

它们现在都有不同的版本。只需将鼠标放在它们上并更正版本号（即，对我来说，是将地图从 15.0.0 升级到 15.0.2 并将标签管理器升级到 15.0.1）
