未找到 Gradle DSL 方法：“classpath()”

项目“FeedBack”可能使用不包含该方法的 Android Gradle 插件版本（例如，在 1.1.0 中添加了“testCompile”）。 修复插件版本并同步项目

你必须插入classpath里面的依赖关系buildscript block.

buildscript {
    repositories {
        jcenter()

        maven { url 'https://maven.fabric.io/public' }
    }

    // move it here
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.0'

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

        // The Fabric Gradle plugin uses an open ended version to react
        // quickly to Android tooling updates
        classpath 'io.fabric.tools:gradle:1.+'
    }
}
