Android support v4 duplicates copies

Hil all,

this my error :

Error:Class android.support.v4.app.ActivityCompatHoneycomb has already
been added to output. Please remove duplicate copies.

and my dependecies are :

dependencies {

compile fileTree(dir: ‘libs’, include: [‘*.jar’])
compile(‘com.android.support:support-v4:22.0.0’) {
exclude group: ‘com.android.support’, module: ‘support-v4’
}
compile (‘com.google.android.gms:play-services:7.0.0’)
compile ‘com.squareup.picasso:picasso:2.5.2’
compile files(‘libs/json-simple-1.1.1.jar’)
compile files(‘libs/ormlite-android-4.45.jar’)
compile files(‘libs/ormlite-core-4.45.jar’)
compile files(‘libs/jackson-databind-2.1.4.jar’)
compile files(‘libs/jackson-core-2.1.4.jar’)
compile files(‘libs/jackson-annotations-2.1.4.jar’)
compile files(‘libs/httpmime-4.1.jar’)
compile files(‘libs/YouTubeAndroidPlayerApi.jar’)
compile files(‘libs/paralloidviews.jar’)
compile files(‘libs/jsr250-api-1.0.jar’)

compile files(‘libs/panoramagl.jar’)
compile project(‘:paymentKit_lib’)
compile project(‘:ProgressWheel-master’)
compile project(‘:UIL_library’)
compile files(‘libs/coverflowlibrary.jar’)

}
so where I could find the duplacte copies, can you help me please, I struggle with this error a long time ago !
I put this error in stackoverflow but no replay, be helpful guys please !

Try running a dependency insight report to see where this dependency might be coming from and exclude it.

$ ./gradlew dependencyInsight --dependency support-v4 --configuration compile
