Android Studio Gradle - Failed to resolve dependency : acra

I am willing to add Acra to my android studio project.

However, although tutorial looks pretty simple , I am unable to get the dependency, and I get the error:

Failed to resolve: ch.acra:acra:4.8.5

Grade File:

buildscript {
    repositories {
        mavenCentral()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.5.0'
        classpath 'com.google.gms:google-services:1.5.0'
    }
}

apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'

dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
    compile 'com.android.support:support-v4:21.+'
    compile 'ch.acra:acra:4.8.5'
    compile 'com.google.android.gms:play-services-location:8.3.0'
    compile ('com.google.android.gms:play-services-analytics:8.3.0') {
        exclude module: 'support-v4'
    }

}

What am I missing?

I also get this in terminal:
