Execution failed for task ':app:dexDebug'

问题

This is my gradle file:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 20
    buildToolsVersion '20.0.0'

    defaultConfig {
        applicationId "com.nifty.eattime.eattime"
        minSdkVersion 15
        targetSdkVersion 20
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    packagingOptions {
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/LICENSE-FIREBASE.txt'
        exclude 'META-INF/NOTICE'
    }

}
dependencies {
    compile files('libs/android-toq-api-1.5.2.jar')
    compile files('libs/firebase-client-android-2.0.3.jar')
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.google.android.gms:play-services:5.0.89'


}

The error i am getting is:

Execution failed for task ':app:dexDebug'.

From what I read, it has to do with a duplication of dependencies. I tried to exclude com.android.support, but it does not work. Helps will be greatly appreciated. Thank you.

You should delete

compile files('libs/android-toq-api-1.5.2.jar')
compile files('libs/firebase-client-android-2.0.3.jar')
compile 'com.google.android.gms:play-services:5.0.89'

leave only

compile fileTree(dir: 'libs', include: ['*.jar'])

I had the same error and I tried it, after that I had no more error.
