无法合并dex Android studio 3.0

问题描述：

我的项目存在一些问题。在Android的工作室2.3.3它工作正常，但当我更新到3.0我有问题，以marge DEX。无法合并dex Android studio 3.0

我清理并重建项目。

什么是错的：

执行失败的任务 '：应用程序：transformDexArchiveWithExternalLibsDexMergerForDebug'。 com.android.builder.dexing.DexArchiveMergerException：无法合并DEX

你已经尝试没有multidex？ –

是的。我试图在Android Studio 2.3.3中运行应用程序，并且它可以工作。所以这是只有当我使用3.0版本 – qubuss

只是一个猜测，但我认为它涉及到重复的依赖关系的问题。因为这个问题发生很多，因为每个人都在更新到Android Studio 3.0。例如[这里]（https://*.com/questions/47086275/trying-to-build-android-project-with-glide-package-throws-unable-to-merge-dex）。我的猜测是，如果关闭multidex库，您可能会看到更好的堆栈跟踪，显示重复错误。 –

答

这与dupl有关你项目中的依赖项。发生了重复的依赖关系，这是因为某些库隐式依赖于相同的库，但具有不同的版本。在Android Studio中使用的Gradle 4.1不支持库复制。

您可以从依赖树用下面的命令在Linux中的终端检查（应用是你的模块名）：

./gradlew app:dependencies

，或者如果你正在使用Windows尝试这种在命令提示符下：

gradlew.bat app:dependencies

然后，在找到它之后，您需要将其从库中排除并仅使用其中一个。事情是这样的：

compile('com.library.name:version') { 
    // this is a case for duplicate support library version. 
    exclude group: 'com.android.support' 
    exclude module: 'appcompat-v7' 
}

需要指出的是，你最好使用的 compileSdkVersion，buildToolsVersion，targetSdkVersion和Support Library相同的版本。

答

在我的情况下，它与awsgateway sdk给出的gson和gson已经存在的依赖性问题有关。

gradle -q app:dependencies

没有显示任何依赖关系的差异，但gradle构建堆栈跟踪显示它与gson相关。引起：com.android.dex.DexException：多个dex文件定义Lcom/google/gson/FieldNamingStrategy;

继此issue之后，我在config下添加了build.gradle，但没有解决问题。

compile("com.google.code.gson:gson:2.3") { 
    exclude module: 'gson:2.2.4' 
}

我不得不手动去除（SDK生成期间由给定apigateway GSON-2.2.4.jar）罐子存在于应用程序/库文件夹。

答

我面临同样的问题，然后我发现从Here (Github)

解决方案在默认配置添加

multiDexEnabled true

为例

defaultConfig { 
    applicationId "my application id " 
    minSdkVersion 14 
    targetSdkVersion 27 
    versionCode 1 
    versionName '1.0' 
    multiDexEnabled true 
}

然后添加

implementation('commons-validator:commons-validator:1.4.1') { 
    exclude group: 'commons-collections', module: 'commons-collections' 
}

在您的依赖项中。这对我来说是我的工作，我希望它也能解决你的问题:)

为什么你认为OP的问题和你的问题（或者LeakCanary列表的问题）是“一样的”？为什么你建议在OPs默认配置中添加'multiDexEnabled true'，当它已经在那里？最后，为什么你建议OP添加一个库而没有给出理由呢？ – kalabalik

我建议，因为我遵循的答案，但它不适合我。我想其他人可能会面临同样的问题，这就是为什么我剪切我如何解决这个问题。 –
