无法合并dex Android studio 3.0 [重复]

Question

我的项目有问题。在 Android Studio 2.3.3 中它工作正常，但是当我更新到 3.0 时，我遇到了 marge dex 的问题。

我清理并重建项目。

怎么了：

任务“:app:transformDexArchiveWithExternalLibsDexMergerForDebug”执行失败。 com.android.builder.dexing.DexArchiveMergerException: 无法合并 dex

堆栈跟踪：

Answer 1

这与您项目中的重复依赖项有关。由于某些库隐式依赖于同一个库但版本不同，因此会发生重复的依赖关系。 Android Studio 中使用的 Gradle 4.1 不允许库重复。

您可以在 Linux 终端中使用以下命令从依赖关系树中检查它（app 是您的模块名称）：

./gradlew app:dependencies

或者如果您使用的是 Windows，请在命令提示符下尝试：

gradlew.bat app:dependencies

那么在你找到它之后，你需要将它从库中排除并且只使用其中的一个。像这样的：

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

请注意，您最好使用相同版本的 compileSdkVersion、buildToolsVersion、targetSdkVersion 和 Support Library。

Answer 2

在我的情况下，它与 awsgateway sdk 给出的 gson 的依赖问题有关，并且 gson 已经存在。

gradle -q app:dependencies

在依赖项中没有显示任何差异，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;

在issue 之后，我在下面的配置中添加了 build.gradle，但这并没有解决问题。

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

我不得不手动删除 app/libs 文件夹中存在的 jar（在 sdk 生成期间由 apigateway 提供的 gson-2.2.4.jar）。

Answer 3

我遇到了同样的问题，然后我从Here (Github)找到了解决方案

添加

multiDexEnabled true

在您的默认配置中 例子

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。 这对我有用，我希望它也能解决你的问题:)
