Gradle 无法构建 ActionBarSherlock

我正在使用基于 IDEA 的新 Android studio，并尝试在主模块的依赖项中使用 ABS 库构建项目。 我收到错误：

Gradle: package com.actionbarsherlock.app does not exist
Gradle: cannot find symbol class SherlockActivity
Gradle: package com.actionbarsherlock.view does not exist
Gradle: cannot find symbol variable super
Gradle: cannot find symbol method setContentView(int)
....

为什么以及如何解决它？

我用构建没问题。

buildscript {
repositories {
    mavenCentral()
}
dependencies {
    classpath 'com.android.tools.build:gradle:0.4'
}
}
apply plugin: 'android-library'

dependencies {
       compile 'com.android.support:support-v4:13.0.0'
}

android {
compileSdkVersion 17
buildToolsVersion "17"

defaultConfig {
    minSdkVersion 7
    targetSdkVersion 17
}
sourceSets {
    main {
        manifest.srcFile 'AndroidManifest.xml'
        java.srcDirs = ['src']
        resources.srcDirs = ['src']
        aidl.srcDirs = ['src']
        renderscript.srcDirs = ['src']
        res.srcDirs = ['res']
        assets.srcDirs = ['assets']
    }

    instrumentTest.setRoot('tests')
}
}
