Android 未知属性'；依赖性'；对于类型为org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler的对象

我正在尝试克隆它，并希望在android studio中打开示例应用程序。然后我得到这个梯度同步错误：

Error(3,0) Could not get unknown property 'dependency' for object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

带有此错误的渐变文件：

buildscript {
    dependencies {
        classpath dependency.spoonGradlePlugin
    }
}

//Load API Key information in from property file
Properties props = new Properties()
try {
    props.load(file('twitter.properties').newDataInputStream())
} catch (Exception ex) {
   // throw new GradleException("Missing twitter.properties, check the twitter.properties.sample file.");
}

我发现依赖项格式看起来不错。如何删除此错误并运行示例应用程序
