Android Studio Build not working after migration from Eclipse - android-studio

Question

I'm migrating my Android project from Eclipse to Android Studio. The original project relied on two apache libraries: commons-io-2.4.jar and commons-codec-1.9.jar.
I've copied these jar files to the proper libs directory and updated build.gradle to reflect this:
dependencies {
compile project(':aviarySDK')
compile project(':showcaseView')
compile 'com.google.code.gson:gson:2.3.1'
compile 'com.google.android.gms:play-services:+'
compile files('libs/commons-cli-1.2.jar')
compile files('libs/httpclient-4.3.1.jar')
compile files('libs/httpcore-4.3.jar')
compile files('libs/httpmime-4.3.1.jar')
compile files('libs/metadata-extractor-2.6.4.jar')
compile files('libs/tape-1.1.0.jar')
compile files('libs/commons-codec-1.9.jar')
compile files('libs/commons-io-2.4.jar')
}
When I try to build the project a I get a duplication error message:
Error:duplicate files during packaging of APK /Users/gkipnis/repos/floomitandroidclient/floomItNewCamera/build/outputs/apk/floomItNewCamera-debug-unaligned.apk
Path in archive: META-INF/LICENSE.txt
Origin 1: /Users/gkipnis/repos/floomitandroidclient/floomItNewCamera/libs/commons-io-2.4.jar
Origin 2: /Users/gkipnis/repos/floomitandroidclient/floomItNewCamera/libs/commons-codec-1.9.jar
You can ignore those files in your build.gradle:
android {
packagingOptions {
exclude 'META-INF/LICENSE.txt'
}
}
Error:Execution failed for task ':floomItNewCamera:packageDebug'.
> Duplicate files copied in APK META-INF/LICENSE.txt

File 2: /Users/gkipnis/repos/floomitandroidclient/floomItNewCamera/libs/commons-io-2.4.jar

Can someone provide any pointers to what might be going on.
Thank You,

As suggested by the error message add this part to your build.gradle
android {
packagingOptions {
exclude 'META-INF/LICENSE.txt'
}
}
