Android Build.gradle DuplicateFileException 错误

Question

所以我尝试将 Firebase SDK 合并到 android studio 中，并且我严格按照文档进行操作。这是我的错误和 Gradle 文件。任何帮助表示感谢，谢谢。

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.firebase/firebase-client-jvm/pom.properties File1: C:\Users\Owner\AndroidStudioProjects\RealChatHusk\app\libs\firebase-client-android-2.5.2.jar File2: C:\Users\Owner.gradle\caches\modules-2\files-2.1\com.firebase\firebase-client-jvm\2.5.2\91731b8f5868a3e8a8a773f29b8d06b5c358f5bb\firebase-client-jvm-2.5.2.jar

    exclude 'META-INF/LICENSE-FIREBASE.txt'
    exclude 'META-INF/NOTICE'
}
 }

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])

testCompile 'junit:junit:4.12'

compile 'com.android.support:appcompat-v7:23.1.1'

compile 'com.android.support:support-v4:23.1.1'

compile 'com.android.support:design:23.1.1'

compile 'com.firebase:firebase-client-android:2.5.2'
}

在 build.gradle 文件中添加以下文本解决问题

packagingOptions {
    exclude  'jsr305_annotations/Jsr305_annotations.gwt.xml'
    exclude  'build-data.properties'
 }

如果出现更多错误 DuplicateFileException 添加文件排除。 喜欢:

错误

Duplicate files copied in APK jsr305_annotations/Jsr305_annotations.gwt.xml 

解决方案

exclude  'jsr305_annotations/Jsr305_annotations.gwt.xml'
