在APK META-INF中复制的重复文件

Question

嗨我刚开始在Android开发中,我正在尝试构建我的apk但我得到了这个erorr.我更新了我的gradle,我得到了副本.我该如何解决这个错误？

Error:Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'.
> com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK META-INF/maven/com.squareup.okhttp/okhttp/pom.properties
    File1: C:\Users\Toshiba\.gradle\caches\modules-2\files-2.1\com.squareup.okhttp\okhttp\2.0.0\4c8d1536dba3812cc1592090dc20c47a4ed3c35e\okhttp-2.0.0.jar
    File2: C:\Users\Toshiba\.gradle\caches\modules-2\files-2.1\com.crashlytics.android\crashlytics\1.1.13\e821eafa1bf489a26bdb71f95078c26785b37a1\crashlytics-1.1.13.jar 

这是我的build.gradle这个错误来了吗？

buildscript {
    repositories {
        maven { url 'http://download.crashlytics.com/maven' }
    }

    dependencies {
        classpath 'com.crashlytics.tools.gradle:crashlytics-gradle:1.+'
    }
}
apply plugin: 'com.android.application'
apply plugin: 'crashlytics'

android {
    compileSdkVersion 20
    buildToolsVersion "20.0.0"

    defaultConfig {
        applicationId "com.mymonas.ngobrol"
        minSdkVersion 14
        targetSdkVersion 20
        versionCode 1
        versionName "0.9.0.68"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

repositories {

    mavenCentral()
    maven { url 'http://download.crashlytics.com/maven' }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'], exclude: 'android-support-v4.jar')
    compile project('libs:floatlabel')
    compile 'com.android.support:support-v4:21.0.0'

我今天使用我们的React Native应用程序遇到了相同或至少非常类似的问题.问题只出现在我的Mac上.我们可以想到的唯一可信的解释是我更新了一堆Android Studio工具,然后gradle无法使用我们的依赖项正确构建.无论如何排除pom.properties和pom.xml从okhttp,我一直得到相同的错误,但事实证明,我只是要排除更多的文件.这是我packagingOptions在build.gradle中的完整内容:

packagingOptions {
  exclude 'META-INF/maven/com.squareup.okhttp3/okhttp/pom.properties'
  exclude 'META-INF/maven/com.squareup.okio/okio/pom.xml'
  exclude 'META-INF/maven/com.squareup.okhttp3/okhttp/pom.xml'
  exclude 'META-INF/maven/com.squareup.okio/okio/pom.properties'
}
