Unsupported method: BaseConfig.getApplicationIdSuffix(). somehting missed in my build.gradle file

Question

i know the problem is stated at : Unsupported method: BaseConfig.getApplicationIdSuffix(), but the thing is that i don't have 'classpath' in builde.gradle file at all to change it. here is the build.gradle content:

apply plugin: 'com.android.application'
android {
    compileSdkVersion 29
    buildToolsVersion "20.0.0"

    defaultConfig {
        minSdkVersion 17
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])


}

android studio 4.0. i am new to android, any help is highly appreciated

In your project's build.gradle file add this

 dependencies {
  classpath "com.android.tools.build:gradle:4.0.0"
  }
