Error:(52, 0) Gradle DSL method not found: 'сo

I tried to use Quickblox API in my program by adding online maven dependencies. I'm using Android Studio.
When I tried to build my program, it shows the following error:

Error:(52, 0) Gradle DSL method not found: `сompile()` Possible causes:
The project 'Nanny Watch' may be using a version of Gradle that does not contain the method.
Open Gradle wrapper file

The build file may be missing a Gradle plugin.
Apply Gradle plugin

Here is the build.gradle(Project:NannyWatch2) file:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.5.0'

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

allprojects {
    repositories {

        jcenter()
    }
}

And here is the build.gradle(Module:App) file:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "com.example.user.nannywatch"

}

There is also this warning: 'dependencies' cannot be applied to '(groovy.lang.Closure)' Image

This is a very strange "bug". When you copied and pasted the Gradle lines from Quickblox, you copied a wrong ASCII code of the letter "c" in the word compile and Gradle would not recognize the word "compile".
