解决DuplicateFileException: Duplicate files copied in APK META-INF/LICENSE（或META-INF/DEPENDENCIES）(示例

Posted 2020-10-16 Sharley

导入eclipse项目时报

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: D:\AndroidStudioProjects\android_client\app\libs\wink-json4j-1.4.jar
File2: D:\AndroidStudioProjects\android_client\app\libs\httpclient-4.5.2.jar

解决办法很简单，在对应报错的模块的build.gradle中添加如下配置即可

android {
    ...
    //为了解决部分第三方库重复打包了META-INF的问题
    packagingOptions {
        exclude ‘META-INF/LICENSE.txt‘
        exclude ‘META-INF/LICENSE‘
    }
}

注意红色字体报的什么就加入什么，列出可能会出现的其他错误解决：

android {  
      
  
    packagingOptions {  
        exclude ‘META-INF/DEPENDENCIES.txt‘  
        exclude ‘META-INF/DEPENDENCIES‘  
        exclude ‘META-INF/LICENSE.txt‘  
        exclude ‘META-INF/LICENSE‘  
        exclude ‘META-INF/NOTICE.txt‘  
        exclude ‘META-INF/NOTICE‘  
        exclude ‘META-INF/notice.txt‘  
        exclude ‘META-INF/license.txt‘  
        exclude ‘META-INF/dependencies.txt‘  
        exclude ‘META-INF/LGPL2.1‘  
    }  
}
