构建脚本错误，不支持的摇篮DSL方法发现：“机器人（）'！

我使用的是Android 0.4.5工作室，并有麻烦同步摇篮。

I'm using Android Studio 0.4.5 and having troubles syncing gradle.

当我尝试这样做，我得到这个错误：

When I try to do that I get this error:

Gradle 'MyApp' project refresh failed: Build script error, unsupported Gradle DSL method found: 'android()'!

我的解决方案包含4个模块。这里是我的根 build.graddle ：

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.8.+'
    }
}

android {    
    packagingOptions {
        exclude 'META-INF/LICENSE.txt'
    }
}

allprojects {
    repositories {
        mavenCentral()
    }
}

和其他人（我删除的依赖为简单起见）

And the others (I removed dependencies for simplicity)

模块1

apply plugin: 'android'

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.8.+'
    }
}buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.8.+'
    }
}

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.1"

    defaultConfig {
        minSdkVersion 9
        targetSdkVersion 19
    }

    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

模块2

apply plugin: 'android-library'

android {
    compileSdkVersion 18
    buildToolsVersion "19.0.1"

    defaultConfig {
        minSdkVersion 8
        targetSdkVersion 17
    }

    release {
        runProguard false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
    }
}

模块3 应用插件：机器人库

Module 3 apply plugin: 'android-library'

android {
    compileSdkVersion 18
    buildToolsVersion "19.0.1"

    defaultConfig {
        minSdkVersion 8
        targetSdkVersion 17
    }

    release {
        runProguard false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
    }
}

模块4

apply plugin: 'android-library'

android {
    compileSdkVersion 17
    buildToolsVersion "19.0.1"

    defaultConfig {
        minSdkVersion 9
        targetSdkVersion 17
    }

    release {
        runProguard false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
    }
}

对不起，让这个这么久，但我越来越绝望这里：（

Sorry for making this so long, but I'm getting desperate here :(
