检查项目的build.gradle文件是否与您的Android Studio版本匹配。该项目可能是为旧版Android Studio编写的。

    buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.3'

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

allprojects {
    repositories {
        jcenter()
        maven{
            url "http://maven.google.com"
        }
    }
}
