Issue while gradle build Duplicate files copied in APK META-INF/LICENSE

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: C:\Users\admin\.gradle\caches\modules-2\files-2.1\com.fasterxml.jackson.core\jackson-annotations\2.2.2\285cb9c666f0f0f3dd8a1be04e1f457eb7b15113\jackson-annotations-2.2.2.jar
    File2: C:\Users\admin\.gradle\caches\modules-2\files-2.1\com.fasterxml.jackson.core\jackson-core\2.2.2\d20be6a5ddd6f8cfd36ebf6dea329873a1c41f1b\jackson-core-2.2.2.jar

I have tried using 

packagingOptions {
    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/license.txt'
}

and this works but I don't want to exclude the licence please tell how I can avoid it with out using this

apply plugin: 'com.android.application'

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.2"

    defaultConfig {
        minSdkVersion 16
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
         release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'

    compile 'com.android.support:appcompat-v7:24.2.1'
    compile 'com.android.support:support-v4:24.2.1'
    compile 'com.android.support:design:24.2.1'

    compile 'com.google.firebase:firebase-core:9.4.0'
    compile 'com.google.firebase:firebase-storage:9.4.0'
    compile 'com.google.firebase:firebase-messaging:9.4.0'
    compile 'com.google.firebase:firebase-auth:9.4.0'
    compile 'com.firebase:firebase-client-android:2.5.2'

    compile 'com.squareup.retrofit2:retrofit:2.1.0'
    compile 'com.squareup.okhttp3:okhttp:3.4.1'
    compile 'com.squareup.retrofit:converter-gson:2.0.0-beta2'
}

here is my gradle which has many dependencies so please let me know which dependencies are causing the issue

You're mixing versions of the Firebase client, which is guaranteed to give you more problems down the line.

Use a single version for all your Firebase dependencies, such as 9.4.0:

compile 'com.google.firebase:firebase-core:9.4.0'
compile 'com.google.firebase:firebase-storage:9.4.0'
compile 'com.google.firebase:firebase-messaging:9.4.0'
compile 'com.google.firebase:firebase-auth:9.4.0'
compile 'com.google.firebase:firebase-database:9.4.0' // this one changed

Edit: If you want to go with the defined dependencies. You need to use the below code: 

 packagingOptions {
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/license.txt'
    }

Otherwise you need to remove the used dependencies as they have conflicts in files.
