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/README.md< !-- 这里提示的是相同文件冲突的名称--> File1: D:\CooKara\cookaraclient\app\libs\youtubevget.jar File2: C:\Users\guoxw\.gradle\caches\modules-2\files-2.1\org.jsoup\jsoup\1.10.3\b842f960942503cf1abbcc8c173a7f2c19d43726\jsoup-1.10.3.jar

1.加入jar包，多个jar包有相同文件产生的问题。
2.解决方法： buile.gradle

apply plugin: ‘com.android.application‘ android { compileSdkVersion 25 buildToolsVersion "25.0.3"
< !--添加的解决方法 --> packagingOptions { exclude ‘META-INF/README.md‘// 该处是上面错误异常提示的文件名 exclude ‘META-INF/CHANGES‘ }
