Android studio error Error:Execution failed for task

Recently, when doing the face recognition check-in system based on Android platform, after importing the third party’s lib package, Android studio reported the following error:

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: E:\Workspaces\Swface\app\libs\httpcore-4.4.4.jar
File2: E:\Workspaces\Swface\app\libs\httpclient-4.5.2.jar

After consulting the data, it is found that there are duplicate contents loaded in the meta-inf directory of the jar package. Open the corresponding jar package
sure enough, both of the two jar packages have license, and further Click to find that the contents are exactly the same. However, it seems that the next three files are also duplicate (only there is no clear prompt in the error report), so we can solve them all at once
all Now that we know that it is caused by repeatedly loading files, the solution is to remove the repeatedly loaded files during compilation. The specific operations are as follows:

1. Open app\ build.gradle File

1. 2. Modify the configuration as follows:

buildTypes {
          ...... (omit part of the code)
          // Add the following code here
          packagingOptions {
            exclude 'META-INF/DEPENDENCIES'
            exclude 'META-INF/NOTICE'
            exclude 'META-INF/LICENSE'
            exclude 'META-INF/LICENSE.txt'
            exclude 'META-INF/NOTICE.txt'
            exclude 'META-INF/ASL2.0'
            exclude 'META-INF/notice.txt'
        }
 }       
``

3. Rebuild project
