Kotlin & Gradle - Make sure you have kotlin-reflect.jar in the classpath

I am working on a app using Kotlin language and Gradle Build in IntelliJ IDEA IDE. I am getting following error:

Exception in thread "main" kotlin.jvm.KotlinReflectionNotSupportedError: Kotlin reflection implementation is not found at runtime. Make sure you have kotlin-reflect.jar in the classpath
    at kotlin.jvm.internal.ClassReference.error(ClassReference.kt:86)
    at kotlin.jvm.internal.ClassReference.getQualifiedName(ClassReference.kt:26)
    at WorkerKt.main(Worker.kt:62)

I have included the dependencies as mentioned in following answer Add kotlin-reflect dependency in gradle

Even I have added the jar file in libs folder but still I am getting above error at runtime.

My Gradle file is as below:

group 'com.working.workerhelp'
version '1.0-SNAPSHOT'

buildscript {
    ext.kotlin_version = '1.2.21'

    repositories {
        mavenCentral()
    }
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

apply plugin: 'kotlin'

repositories {
    mavenCentral()
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile "org.jetbrains.kotlin:kotlin-stdlib-jre8:$kotlin_version"
    compile "org.jetbrains.kotlin:kotlin-reflect:$kotlin_version"
    testCompile "org.jetbrains.kotlin:kotlin-test:$kotlin_version"
}

compileKotlin {
    kotlinOptions.jvmTarget = "1.8"
}
compileTestKotlin {
    kotlinOptions.jvmTarget = "1.8"
}

Is there something I need to configure for Gradle Build or am I missing something?

add implementation "org.jetbrains.kotlin:kotlin-reflect:$kotlin_version" in build.gradle(Module:app)

remove compile "org.jetbrains.kotlin:kotlin-reflect:$kotlin_version" from project level build.gradle
