Android build system gradle

I am testing androids new build system which still is in beta. I have implemented some code which generates following error: ``` No such property: resolutionResult for class: org.gradle.api.internal.artifacts.ivyservice.ErrorHandlingArtifactDependencyResolver$ErrorHandlingResolvedConfiguration ``` build.gradle ``` buildscript { repositories { mavenCentral() } dependencies { classpath 'com.android.tools.build:gradle:0.2' } } apply plugin: 'android' android { sourceSets { main { manifest { srcFile 'AndroidManifest.xml' } java { srcDir 'src' } res { srcDir 'res' } assets { srcDir 'assets' } resources { srcDir 'src' } } } } ``` I have tried samples too, which raises the same error. What's wrong? Gradle Version ``` ------------------------------------------------------------ Gradle 1.3 ------------------------------------------------------------ Gradle build time: Dienstag, 20.
