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