Android Gradle Duplicate Files Copied to APK META-INF / license.txt

Question

I am going to add RESTful Web Service support using Spring to my Android app, as described here https://spring.io/guides/gs/consuming-rest-android/ .

This is the top level build.gradle configuration:

// Top-level build file where you can add configuration options common to all sub-projects/modules. buildscript { repositories { jcenter() } dependencies { classpath 'com.android.tools.build:gradle:2.1.0' } } allprojects { repositories { jcenter() } } 

This is my app/build.gradle config:

 apply plugin: 'com.android.application' android { compileSdkVersion 23 buildToolsVersion "23.0.3" defaultConfig { applicationId "com.example" minSdkVersion 8 targetSdkVersion 17 } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt' } } dependencies { compile 'com.android.support:appcompat-v7:+' compile fileTree(dir: 'libs', include: ['*.jar']) compile 'org.springframework.android:spring-android-rest-template:1.0.1.RELEASE' compile 'com.fasterxml.jackson.core:jackson-databind:2.3.2' } packagingOptions { exclude 'META-INF/NOTICE' // will not include NOTICE file exclude 'META-INF/LICENSE' // will not include LICENSE file } } 

This is currently happening with the following error:

 FAILURE: Build failed with an exception. * What went wrong: 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.txt File1: user\.gradle\caches\modules-2\files-2.1\org.springframework.android\spring-android-rest-template\1.0.1.RELEASE\e132d929bd181941f79b0d63edafb8a86ae6fd33\spring-android-rest-template-1.0.1.RELEASE.jar File2: user\.gradle\caches\modules-2\files-2.1\org.springframework.android\spring-android-core\1.0.1.RELEASE\e68f0e8e4b636ee30c4de58953be38d9b72a5e3b\spring-android-core-1.0.1.RELEASE.jar 

What am I doing wrong and how to fix it?

Answer 1

Write below lines at the level of your application gradle

 android { packagingOptions { exclude 'META-INF/DEPENDENCIES.txt' exclude 'META-INF/LICENSE.txt' exclude 'META-INF/NOTICE.txt' exclude 'META-INF/NOTICE' exclude 'META-INF/LICENSE' exclude 'META-INF/DEPENDENCIES' exclude 'META-INF/notice.txt' exclude 'META-INF/license.txt' exclude 'META-INF/dependencies.txt' exclude 'META-INF/LGPL2.1' } } 

Answer 2

If the solution in the selected answer does not fix your problem, try adding

  exclude 'META-INF/ASL2.0' 

. Or basically, specify the name of the duplicate file and exclude it. Adding above fixed the problem for me.

Answer 3

It helps me. Try this code :)

 packagingOptions { exclude 'META-INF/LICENSE' exclude 'META-INF/NOTICE' } 

Answer 4

This worked for me:

  packagingOptions { exclude 'META-INF/DEPENDENCIES.txt' exclude 'META-INF/LICENSE.txt' exclude 'META-INF/NOTICE.txt' exclude 'META-INF/NOTICE' exclude 'META-INF/LICENSE' exclude 'META-INF/DEPENDENCIES' exclude 'META-INF/notice.txt' exclude 'META-INF/license.txt' exclude 'META-INF/dependencies.txt' exclude 'META-INF/LGPL2.1' exclude 'META-INF/spring.schemas' exclude 'META-INF/spring.tooling' exclude 'META-INF/INDEX.LIST' exclude 'META-INF/spring.handlers' } configurations { all*.exclude module: 'classworlds' all*.exclude module: 'commons-logging' all*.exclude module: 'httpclient' all*.exclude module: 'maven-artifact' all*.exclude module: 'maven-artifact-manager' all*.exclude module: 'maven-error-diagnostics' all*.exclude module: 'maven-model' all*.exclude module: 'maven-project' all*.exclude module: 'maven-settings' all*.exclude module: 'plexus-container-default' all*.exclude module: 'plexus-interpolation' all*.exclude module: 'plexus-utils' all*.exclude module: 'wagon-file' all*.exclude module: 'wagon-http-lightweight' all*.exclude module: 'wagon-provider-api' } 

Answer 5

adding these lines helped me.
