AndroidStudioGradle错误"多个dex文件定义..."

我的项目工作正常,当我将facebook sdk添加到我的项目中时我有这样的错误,我已经尝试了很多方法来解决这个问题,但我没有.我该怎么办？

  Error:Execution failed for task ':app:packageAllDebugClassesForMultiDex'.
> java.util.zip.ZipException: duplicate entry: bolts/AggregateException.class

我的App gradle在下面

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion '21.1.2'

    defaultConfig {
        applicationId "com.example.myproject"
        minSdkVersion 9
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
        multiDexEnabled = true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7

}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:21.0.3'

    compile project(':facebook')

这是facebook build.gradle

现在他们将bolt-android拆分为bolt-applinks和bolt-tasks.所以你需要从gradle构建中排除这两者

compile ('com.facebook.android:facebook-android-sdk:4.10.0'){
exclude group: 'com.parse.bolts',
        module: 'bolts-tasks'
exclude group: 'com.parse.bolts',
        module: 'bolts-applinks';}

这对我来说非常有用!!!!

对我来说,我将Facebook SDK添加为项目,并将其设置为依赖项.

但是,切换到使用maven源后,排除工作.

我认为它仅适用于maven,而不适用于项目依赖项？(如果有人知道,请提供正确的信息)

换句话说,您现在可以删除Facebook SDK项目和文件.

记得加

repositories {
    mavenCentral()
}

如果你不使用maven.

所以build.gradle看起来像这样,我评论了项目的方式.

repositories {
    mavenCentral()
}
dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
    compile project(':google-play-services_lib')
    compile ('com.facebook.android:facebook-android-sdk:3.23.0'){
        exclude module: 'bolts-android'
        exclude module: 'support-v4'
    }
//    compile (project(':FacebookSDK')){
//        exclude module: 'bolts-android'
//        exclude module: 'support-v4'
//    }
    compile (project(':UserVoiceSDK')){ exclude module: 'support-v4' }
}

我有类似的问题.这对我来说真的很令人沮丧,因为一切都很好,突然间它无缘无故地破了.

这个问题暗示着duplicate entry: bolts/AggregateException.class.这是Bolts图书馆的冲突,由Facebook和Parse使用.

对我来说,问题在于以下两点:

compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.parse.bolts:bolts-android:1.1.4'

我下载了Parse库并将它们放在/libs/文件夹中.问题是该bolts-android文件夹中有另一个文件.

解决方案是删除该库并保留该compile 'com.parse.bolts:bolts-android:1.1.4'部分.

替代问题

就我而言,我使用的是compile 'com.parse.bolts:bolts-android:1.+'代替特定版本.这始终采用最新版本.因此,当bolts升级到版本时1.2.0,事情似乎随机突破,因为/libs/文件夹中的版本和最新版本突然不再对齐.

最佳做法是避免1.+样式版本控制,并且不时地检查和更新到最新版本.

希望这有助于某人.
