android studio error: transformClassesWithJarMergingForDebug

Question

I'm currently testing a game. But when I try to run the app on my device, it gives me this error:

enter image description here

I already tried cleaning the project, but the error stays.

Project:

BaseGameUtils: (Library) I needed this for implementing GPS

apply plugin: 'com.android.library'

buildscript {

    }

    dependencies {
        classpath 'com.android.tools.build:gradle:1.3.1'
    }
}

dependencies {
    // Set defaults so that BaseGameUtils can be used outside of BasicSamples
    if (!project.hasProperty('appcompat_library_version')) {
        ext.appcompat_library_version = '20.0.+'
    }
    if (!project.hasProperty('support_library_version')) {
        ext.support_library_version = '20.0.+'
    }
    if (!project.hasProperty('gms_library_version')) {
        ext.gms_library_version = '8.4.0'
    }

    compile "com.android.support:appcompat-v7:${appcompat_library_version}"
    compile "com.android.support:support-v4:${support_library_version}"
    compile "com.google.android.gms:play-services-games:${gms_library_version}"
    compile "com.google.android.gms:play-services-plus:${gms_library_version}"
}

android {
    // Set defaults so that BaseGameUtils can be used outside of BasicSamples
    if (!project.hasProperty('android_compile_version')) {
        ext.android_compile_version = 23
    }
    if (!project.hasProperty('android_min_version')) {
        ext.android_min_version = 9
    }
    if (!project.hasProperty('android_version')) {
        ext.build_tools_version = "23.0.2"
    }

    compileSdkVersion android_compile_version
    buildToolsVersion build_tools_version

    defaultConfig {
        minSdkVersion android_min_version
        targetSdkVersion android_compile_version
    }
}

You've compiled too many Google Play Services. But, you really should show your `build.gradle` file — OneCricketeer, Oct 13 '16 at 17:53
@cricket_007 i have added the screenshots from my project gradle and the basegameutils. Is this what you needed? — MrN2017, Oct 13 '16 at 18:04
I had [this](http://stackoverflow.com/questions/30648172/gradle-library-duplicates-in-dependencies) bookmarked some time ago. — Oki Doki, Oct 13 '16 at 18:16

I would recommend you set a variable for the google services and make them all the same version.

For example, your BaseGameUtils uses 8.4.0 consistently, but your project is using various other versions (9.6.1 and 9.4.0)

ext {
    appName = "RocketHedgehog"
    gms_library_version = "8.4.0" // For consistency with library

Then, update these lines to use that variable.

    compile "com.google.android.gms:play-services-ads:${gms_library_version}"
    compile "com.google.android.gms:play-services-games:${gms_library_version}"
