Android studio gradle duplicate files dagger compiler

Question

having strange problem after updating android studio to 0.4.0 and gradle plugin to 0.7.1 and gradle version to 1.9 with dagger compiler

build.gradle

android {
packagingOptions {
    exclude 'META-INF/DEPENDENCIES.txt'
    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INF/NOTICE.txt'
}
}
    dependencies {
    compile 'com.android.support:support-v4:+'
    compile 'com.android.support:support-v13:19.0.+'
    compile 'com.google.code.gson:gson:2.2.4'
    compile 'com.squareup.dagger:dagger:1.2.0'
    compile 'com.squareup.dagger:dagger-compiler:1.2.0'
}

on build getting this error

Execution failed for task ':MyApplication:packageDebug'.

Duplicate files copied in APK META-INF/services/javax.annotation.processing.Processor File 1: C:\Users\Mantas.gradle\caches\modules-2\files-2.1\com.squareup.dagger\dagger-compiler\1.2.0\22633bb84433e03d345a83e7b0c08c66768be30\dagger-compiler-1.2.0.jar File 2: C:\Users\Mantas.gradle\caches\modules-2\files-2.1\com.squareup.dagger\dagger-compiler\1.2.0\22633bb84433e03d345a83e7b0c08c66768be30\dagger-compiler-1.2.0.jar

if dagger compiler lines is commented everything works fine

If you know which files are being duplicated you can always compile them with exceptions like this:

dependencies {
   compile('com.squareup.dagger:dagger:1.2.0') {
   exclude module: 'moduleName' //by artifact name
   exclude group: 'groupName' //by group
   exclude group: 'com.unwanted', module: 'moduleName' //or by both
   }
   compile 'com.squareup.dagger:dagger-compiler:1.2.0'
}

Just be sure that when you are doing this you enclose the dependancy in () to use the enclosure or it wont work.
