My Android Advanced tour------> resolution: Execution failed for task & #39;: App:transformresourceswithmergejavaresfordebug & #39;.

Description of the error

Today, I added the Jackson development package to the Android Studio project, which was compiled at the time of execution. An error such as the following is raised:

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/NOTICE    File1: D:\Code\XTCKuwoWatch\app\libs\jackson-core-2.4.4.jar    File2: D:\Code\XTCKuwoWatch\app\libs\jackson-databind-2.4.4.jar

Errors such as the following are seen:

How to Solve

This appears to be due to the inclusion of the same file (NOTICE.txt) in multiple jar packages. Causes errors when packaging is caused by worrying about each other's coverage issues. Try adding a configuration in the Android section of Build.gradle under app. As the following code sees:

{        exclude ‘META-INF/LICENSE‘        exclude ‘META-INF/NOTICE‘    }

• Build.gradle file before the change

apply plugin:  ' com.android.application '  android { Compilesdkversion 22  buildtoolsversion  "22.0.1"  defaultconfig {applicationid  "com.oyp.csdn"  minsdkversion 16  targetsdkversion 23  versioncode 1  versionname " 1.0 "} buildtypes {release {min ifyenabled false  proguardfiles getdefaultproguardfile ( ' proguard-android.txt ' ),  ' Proguard-rules.pro ' }}}dependencies {C Ompile Filetree (dir :  ' Libs ' , include: [ ' *.jar ' ])} 

• Build.gradle files after the change
