Error:Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'

So I'm continuously receiving a gradle build error upon trying to run my project. I have searched for other solutions and some say that adding:

packagingOptions {
exclude 'META-INF/NOTICE'
}

to my app's gradle.build would fix the issue, however, it doesn't. Here is what my app's gradle.build currently looks like.

apply plugin: 'com.android.application'apply plugin: 'com.google.gms.google-services'dependencies {compile fileTree(include: ['*.jar'], dir: 'libs')compile 'com.google.android.gms:play-services:8.3.0'compile 'com.google.android.gms:play-services-ads:8.3.0'compile 'com.google.android.gms:play-services-identity:8.3.0'compile 'com.firebase:firebase-client-android:2.3.1'}android {compileSdkVersion 23buildToolsVersion '23.0.1'useLibrary 'org.apache.http.legacy'defaultConfig {applicationId "com.example.j.airportmeet"minSdkVersion 18targetSdkVersion 23versionCode 1versionName "1.0"multiDexEnabled true}packagingOptions {
exclude 'META-INF/NOTICE'
}buildTypes {release {minifyEnabled falseproguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'}}}

EDIT: The full error is this:

Error:Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'.

解决方法：

As the error message suggests you are not excluding the

META-INF/LICENSE

file which exists in more than one of your dependenciescom.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK META-INF/LICENSE

packagingOptions {exclude 'META-INF/NOTICE' // will not include NOTICE fileexclude 'META-INF/LICENSE' // will not include LICENSE file}
