android - gradle构建错误: app:dexDebug

Question

我想启动我的应用程序“app”，我在构建 gradle 时遇到错误:

Error:Execution failed for task ':app:dexDebug'. com.android.ide.common.internal.LoggedErrorException: Failed to run command: C:\Users\jaafar\AppData\Local\Android\sdk\build-tools\21.1.2\dx.bat --dex --no-optimize --output C:\Users\jaafar\AndroidStudioProjects\helooandroidstudio\app\build\intermediates\dex\debug --input-list=C:\Users\jaafar\AndroidStudioProjects\helooandroidstudio\app\build\intermediates\tmp\dex\debug\inputList.txt Error Code: 2 Output: UNEXPECTED TOP-LEVEL EXCEPTION: com.android.dex.DexException: Multiple dex files define Lcom/facebook/AccessToken$1; at com.android.dx.merge.DexMerger.readSortableTypes(DexMerger.java:596) at com.android.dx.merge.DexMerger.getSortedTypes(DexMerger.java:554) at com.android.dx.merge.DexMerger.mergeClassDefs(DexMerger.java:535) at com.android.dx.merge.DexMerger.mergeDexes(DexMerger.java:171) at com.android.dx.merge.DexMerger.merge(DexMerger.java:189) at com.android.dx.command.dexer.Main.mergeLibraryDexBuffers(Main.java:454) at com.android.dx.command.dexer.Main.runMonoDex(Main.java:303) at com.android.dx.command.dexer.Main.run(Main.java:246) at com.android.dx.command.dexer.Main.main(Main.java:215) at com.android.dx.command.Main.main(Main.java:106)

这是我的build.gradle

apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion "21.1.2"

defaultConfig {
    applicationId "com.heloo"
    minSdkVersion 9
    targetSdkVersion 21
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
compile 'com.facebook.android:facebook-android-sdk:+'
compile 'com.vk:androidsdk:+'
compile 'org.altbeacon:android-beacon-library:2+@aar'
compile 'com.mcxiaoke.volley:library:1.+'
compile project(':reco-sdk-android_0.1.55')
compile project(':reco-sdk-android_0.1.5_JavaDoc')
compile project(':facebook')
 }

这是我的更新的build.gradle

apply plugin: 'com.android.application'

android {
compileSdkVersion 21
buildToolsVersion "21.1.2"

defaultConfig {
    applicationId "com.heloo"
    minSdkVersion 9
    targetSdkVersion 21
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}
   dexOptions { 
   preDexLibraries = false 
  }
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
compile 'com.facebook.android:facebook-android-sdk:+'
compile 'com.vk:androidsdk:+'
compile 'org.altbeacon:android-beacon-library:2+@aar'
compile 'com.mcxiaoke.volley:library:1.+'
compile project(':reco-sdk-android_0.1.55')
compile project(':reco-sdk-android_0.1.5_JavaDoc')
compile project(':facebook')

Answer 1

我打算将其作为答案而不是评论发布

您应该将此代码添加到您的 build.gradle

dexOptions { 

preDexLibraries = false
