错误：执行任务失败：app：transformResourcesWithMergeJavaResForDebug'

所以我试图运行我的项目时不断收到一个gradle生成错误。 我已经寻找其他的解决scheme，有人说，增加：

packagingOptions { exclude 'META-INF/NOTICE' } 

到我的应用程序的gradle.build将解决这个问题，但是，它不。 这是我的应用程序的gradle.build目前的样子。

 apply plugin: 'com.android.application' apply plugin: 'com.google.gms.google-services' dependencies { compile fileTree(include: ['*.jar'], dir: 'libs') compile 'com.google.android.gms:play-services:8.3.0' compile 'com.google.android.gms:play-services-ads:8.3.0' compile 'com.google.android.gms:play-services-identity:8.3.0' compile 'com.firebase:firebase-client-android:2.3.1' } android { compileSdkVersion 23 buildToolsVersion '23.0.1' useLibrary 'org.apache.http.legacy' defaultConfig { applicationId "com.example.j.airportmeet" minSdkVersion 18 targetSdkVersion 23 versionCode 1 versionName "1.0" multiDexEnabled true } packagingOptions { exclude 'META-INF/NOTICE' } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } }

完整的错误是这样的：

 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/LICENSE File1: .gradle\caches\modules-2\files-2.1\com.fasterxml.jackson.core\jackson-databind\2.2.2\3c8f6018eaa72d43b261181e801e6f8676c16ef6\jackson-databind-2.2.2.jar File2: .gradle\caches\modules-2\files-2.1\com.fasterxml.jackson.core\jackson-core\2.2.2\d20be6a5ddd6f8cfd36ebf6dea329873a1c41f1b\jackson-core-2.2.2.jar File3: .gradle\caches\modules-2\files-2.1\com.fasterxml.jackson.core\jackson-annotations\2.2.2\285cb9c666f0f0f3dd8a1be04e1f457eb7b15113\jackson-annotations-2.2.2.jar 

Answer 1

由于错误消息表明您不排除存在于多个依赖关系中的META-INF/LICENSE文件

com.android.build.api.transform.TransformException：com.android.builder.packaging.DuplicateFileException：复制在APK META-INF / LICENSE中复制的文件

 packagingOptions { exclude 'META-INF/NOTICE' // will not include NOTICE file exclude 'META-INF/LICENSE' // will not include LICENSE file // as noted by @Vishnuvathsan you may also need to include // variations on the file name. It depends on your dependencies. // Some other common variations on notice and license file names exclude 'META-INF/notice' exclude 'META-INF/notice.txt' exclude 'META-INF/license' exclude 'META-INF/license.txt' } 

Answer 2

在我的情况下，我有两个引用到同一个库.jar，只删除其中一个，瞧，现在正在编译，它正在工作。

Answer 3

我面临同样的问题。 在我的情况下，通过将下面的代码添加到build.gradle（模块：应用程序）解决了这个问题

 packagingOptions { exclude 'META-INF/NOTICE' // will not include NOTICE file exclude 'META-INF/LICENSE' // will not include LICENSE file // as noted by @Vishnuvathsan you may also need to include // variations on the file name. It depends on your dependencies. // Some other common variations on notice and license file names exclude 'META-INF/notice' exclude 'META-INF/notice.txt' exclude 'META-INF/license' exclude 'META-INF/license.txt' }
