aviary - duplicate entry AbsHListView in my Android Project -

i working on 1 android application, using 2 libraries ( aviary android sdk , printio sdk)

getting conflict in libraries , getting error each time when compiling project :

 error:execution failed task ':app:transformclasseswithjarmergingfordebug'. > com.android.build.api.transform.transformexception: java.util.zip.zipexception: duplicate entry: it/sephiroth/android/library/widget/abshlistview$1.class 

i have not used such library anywhere in project checked in both libraries, not found anything.

please suggest me why getting conflict in project?

edit :

here build.gradle file :

apply plugin: 'com.android.application'    repositories {     mavencentral()     jcenter()     mavenlocal()     maven {         name 'maven.aviary.com'         url uri("http://maven.aviary.com/repo/release")     } }  buildscript {     repositories {         mavencentral()     }     dependencies {         classpath 'com.android.tools.build:gradle:1.5.0'     } }  android {     compilesdkversion 23     buildtoolsversion "22.0.1"      lintoptions {         disable 'missingtranslation'     }     defaultconfig {         applicationid "xxxxx.xxxxx"         minsdkversion 14         targetsdkversion 23         versioncode 1         versionname "1.0"         renderscripttargetapi 18         renderscriptsupportmodeenabled true         multidexenabled true     }     packagingoptions {         exclude 'lib/armeabi-v7a/librsjni.so'         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'     }     buildtypes {         release {             minifyenabled false             proguardfiles getdefaultproguardfile('proguard-android.txt'), 'proguard-rules.pro'         }     } }  dependencies {     compile filetree(include: ['*.jar'], dir: 'libs')     compile files('libs/httpclient-4.0.1.jar')     compile files('libs/httpcore-4.0.1.jar')     compile project(':materialdialog')     compile files('libs/universal-image-loader-1.9.1.jar')     compile project(':staggeredgrid')     compile project(':customfloatingbuttonlibrary')     compile files('libs/dropbox-android-sdk.jar')     compile files('libs/gcm.jar')     compile project(':image_select_lib')     compile files('libs/json-simple-1.1.1.jar')     compile project(':chipslib')     compile files('libs/aws-android-sdk-1.4.3-s3.jar')     compile 'com.android.support:appcompat-v7:23.1.1'     compile 'com.android.support:design:23.1.1'       compile 'com.instabug.library:instabugsupport:1.+'     //    compile 'com.aviary.android.feather.sdk:aviary-sdk:3.6.3'     compile 'com.yalantis:phoenix:1.2.3'     compile 'com.squareup.picasso:picasso:2.3.2'     compile 'com.google.android.gms:play-services-location:7.5.0'     compile project(':aviary-sdk')     compile project(':swipylib')     compile project(':printio') } 

edit 2 :

i searched library (abshlistview) using ctrl + n , result in following :

i did google search class it/sephiroth/android/library/widget/abshlistview$1.class , found out used library here.

looks 1 of dependencies using library. if on windows press ctrl + n , enter abshlistview , search. find conflicting class.

edit: change dependency this:

compile project(':printio') {    exclude group: 'it.sephiroth.android.library.widget' }
