Gradle error "Attribute "xxx" has already been defined" in Android Studio

Question

I created a project in Android Studio and added a few dependencies using Maven Central and when I try to compile, I run into this type of errors:

Error:Gradle: Attribute "titleTextStyle" has already been defined
Error:Gradle: Attribute "subtitleTextStyle" has already been defined
[...]

And so on... Here is my build.gradle file:

buildscript {
    repositories {
    mavenCentral()
    }
    dependencies {
    classpath 'com.android.tools.build:gradle:0.5.+'
    }
}
apply plugin: 'android'

repositories {
    mavenCentral()
}

android {
    compileSdkVersion 18
    buildToolsVersion "17.0.0"

    defaultConfig {
    minSdkVersion 8
    targetSdkVersion 18
    }
}

dependencies {
    // Support Libraries
    compile 'com.android.support:support-v4:18.0.0'
    compile 'com.android.support:appcompat-v7:18.0.0'
    compile 'com.android.support:support-v13:18.0.0'

    // Third-Party Librairies
    compile 'com.actionbarsherlock:actionbarsherlock:4.4.0@aar'
    compile 'ch.acra:acra:4.5.0'

}

Sadly the Make Console doesn't speak as much as Eclipse's Console, so I have no idea of the problem's origin. Does anyone have an idea of what causes these compile errors?

You should remove this line in your dependencies :

compile 'com.android.support:appcompat-v7:18.0.0'

You checked the 'Action Bar' checkbox in the 'New Project' wizzard – passsy Oct 04 '13 at 14:43
Thanks, I got a truly maddening "Attribute "color" has already been defined" for a line unrelated to color in any way (or so it seems), and this fixed it. – Atorian Nov 01 '14 at 21:39
how this has anything to do with color or text attribute? ;( – Ewoks Sep 01 '15 at 12:31

The last version of Google Play Services now uses appcompat-v7, so u can't use it with actionbarsherlock. You have to use only appcompat-v7 or the previous version of play services:

compile 'com.google.android.gms:play-services:7.0.0'

This was the exact reason I was getting this error. The gradle output didn't even mention which files were involved in the conflict. Changing the GPS version fixed it. – black Oct 08 '15 at 05:29
Thank you for your knowledge. Is '7.0.0' the last one which can use ABS or do I have to try '6.5.87'? – Wooseong Kim Mar 08 '16 at 14:11
I'm not completely sure what is the last one but 7.0.0 and oldest versions should work, although I recommend you to use the last version of play services with AppCompat only. – pedroca Mar 08 '16 at 23:27
