java - Error: more than one library with package name 'com.google.maps.android' -

i added library in project encounter error :

    error:execution failed task ':app:processdebugresources'.     > error: more 1 library package name 'com.google.maps.android'     can temporarily disable error android.enforceuniquepackagename=false     however, temporary , enforced in 1.0 

how avoid error? tried solution found on internet :

• add android.enforceuniquepackagename=false

• eclude group {com.google.maps.android}

but no success.

here app build.gradle :

apply plugin: 'com.android.application'  android { compilesdkversion 23 buildtoolsversion "23.0.0"  defaultconfig {     applicationid "me.eazypark.eazypark"     minsdkversion 15     targetsdkversion 23     versioncode 1     versionname "1.0" } buildtypes {     release {         minifyenabled false         proguardfiles getdefaultproguardfile('proguard-android.txt'), 'proguard-rules.pro'     } } }  dependencies { compile project(':library') compile filetree(dir: 'libs', include: ['*.jar']) testcompile 'junit:junit:4.12' repositories {     mavencentral() } compile 'com.android.support:appcompat-v7:24.0.0-alpha1' compile 'com.google.android.gms:play-services-maps:8.4.0' compile 'com.google.maps.android:android-maps-utils:0.3.+' compile 'com.android.support:design:24.0.0-alpha1' compile 'com.google.android.gms:play-services:8.4.0' compile 'com.mcxiaoke.volley:library-aar:1.0.0' compile 'com.sothree.slidinguppanel:library:3.0.0' }

tanks!

in build.gradle, dont need add both compile 'com.google.android.gms:play-services:8.4.0' , compile 'com.google.android.gms:play-services-**:8.4.0'. either should define play-services using , or need add compile 'com.google.android.gms:play-services:8.4.0' only..
