Check that your build.gradle file for your project matches your version of Android Studio. It is possible that the project was written for an older version of Android Studio.

    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"
        }
    }
}
