Cannot resolve symbol 'github' in android

I am trying to import github in android development like below.

import com.github.pires.obd.commands.protocol.EchoOffCommand; import com.github.pires.obd.enums.ObdProtocols;

But getting error message like Cannot resolve symbol 'github'

build.gradle

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

buildscript {
repositories {
    google()
    jcenter()

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

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

allprojects {
repositories {
    jcenter()
    maven {
        url 'https://jitpack.io'
    }

}
 }

task clean(type: Delete) {
delete rootProject.buildDir
}
