Multiple dex files define Landroid/support/v4/ in android studio

Question

I can integrate (add & work) with many libraries.

But as for ActionBarSherlock library, I have so many problems with it.

First Issue is the popular issue Multiple dex files define,

I know The duplicated android-support-v4.jar causes it, but I can not solve this issue now :

Error:Execution failed for task ':fitness:dexDebug'.

Error Code:
2
Output:
UNEXPECTED TOP-LEVEL EXCEPTION:
com.android.dex.DexException: Multiple dex files define Landroid/support/v4/accessibilityservice/AccessibilityServiceInfoCompat$AccessibilityServiceInfoVersionImpl;

I followed the answer in same error. It used :

dependencies {
    compile('...') {
      exclude module: 'support-v4'
    }

    compile 'com.android.support:support-v4:18.0.+'
}

But I received Second Issue : unsupported Gradle DSL method found: 'exclude()'! error. Therefore I changed build.gradle of main module like this:

//configurations {
//    all*.exclude group: 'com.android.support', module: 'support-v4'
//}

dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
    compile project(':google-play-services')
    compile files('/google-play-services/libs/google-play-services.jar')
    compile (project(':actionbarsherlock')) {
        exclude(module: 'support-v4')
    }
    compile 'com.android.support:support-v4:18.0.+'
}

Solved Second Issue, But still get First Issue Multiple dex files define error.

I read many topics, but can not solve First Issue now,

Please help me,

Thanks,

p/s : I can sync with Gradle successully, but when run, it get above errors.

I used Android studio 0.5.5

EDIT

build.gradle of ActionBarSherlock, it has only one android-support-v4.jar:

dependencies {
        compile fileTree(dir: 'libs', include: '*.jar')
}

setting.gradle like this :

include ':fitness', ':google-play-services',':actionbarsherlock'

@Garbriele : I updated new question, show build.gradle of project and build.gradle of main module build.gradle of project:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.9.+'
    }
}

build.gradle of main module after edited :

dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
    compile 'com.actionbarsherlock:actionbarsherlock:4.4.0@aar' // Get following error in this line
} 

I got this error in below :

Okay, thanks for @Garbriele comment, I already fixed this by using this :

repositories {
            mavenCentral()
        }
dependencies {
        compile fileTree(dir: 'libs', include: '*.jar')
        compile 'com.actionbarsherlock:actionbarsherlock:4.4.0@aar' // Get following error in this line
    } 

EDIT 2 When I put like this :

repositories {
            mavenCentral()
        }
dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
    compile 'com.google.android.gms:play-services:+'
}

Still get First Issue Multiple dex files define error.

What I want now is how to add com.google.android.gms:play-services library via Maven successfully,

Please help me,

Thanks,

UPDATE

After followed these steps :

• Put the library via Maven in build.gradle of main module : compile 'com.google.android.gms:play-services:+'

• Restart Android Studio

• Sync project with gradle

No longer get this error again.

Answer 1

So strange,

When I setup my dependencies like this :

repositories {
            mavenCentral()
        }
dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
    compile 'com.google.android.gms:play-services:+'
}

I still get the First Issue Multiple dex files define error.

But after following these steps:

• Put the library via Gradle in build.gradle of main module : compile 'com.google.android.gms:play-services:+'

• Restart Android Studio

• Sync project with gradle

I no longer get this error.

Answer 2

I had duplicate libraries in my libs directory:

$ ls -la libs/
total 80
drwxr-xr-x   5  wheel    170 25 Sep 22:09 .
drwxr-xr-x  10  wheel    340 25 Sep 22:07 ..
-rw-r--r--   1  wheel   3736 25 Sep 21:36 ApiComponent.jar
-rw-r--r--   1  wheel  28741 25 Sep 21:36 DependencyService.jar
-rw-r--r--   1  wheel   3736 25 Sep 22:09 classes.jar

Removing classes.jar worked for me. I modified my DependencyService Project to produce DependencyService.jar instead of classes.jar causing the duplication.
