Android : AndroidStudio (0.8.9 Mac) New Project Grandle Failed to Sync

I'm kind of blocked during my evaluation of Android Studio (0.8.9 on Mac) due to a grandle synchronization error.

I have already searched for other issues like that on StackOverflow (such as Gradle project refresh failed (AS 0.8.2, Mac)) but without finding a solution.

Immediately when I create a new Android project using Android Studio, I got the following error:

Error:Unable to find method 'org.slf4j.spi.LocationAwareLogger.log(Lorg/slf4j/Marker;Ljava/lang/String;ILjava/lang/String;[Ljava/lang/Object;Ljava/lang/Throwable;)V'. Possible causes for this unexpected error include:

• Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.) Re-download dependencies and sync project (requires network)


• The state of a Gradle build process may be corrupt. Stop Gradle daemons and sync project

In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.

My build.grandle file is the following:

buildscript {
    repositories {
       jcenter()
   }
   dependencies {
       classpath 'com.android.tools.build:gradle:0.12.2'

       // NOTE: Do not place your application dependencies here; they belong
      // in the individual module build.gradle files
    }
   }

allprojects {
    repositories {
        jcenter()
    }
}

and grandle-wrapper.properties is:

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=http\://services.gradle.org/distributions/gradle-1.12-all.zip

I hope you can help me to find a solution.

Thanks
