Gradle project sync failed after updating the Android Studio and Gradle

Question

After applying the update of Gradle to version 3.3.0 in Android Studio an error occurred while syncing Gradle regarding the junit 4.12.

The error is : Could not find method testImplementation() for arguments [junit:junit:4.12] on object of type `org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

There was no error before update. The error occurs when I add the last three dependencies (junit, test runner, test espresso) to the gradle file. I've look at the previous questions but couldn't find a solution yet. Here is my gradle files:

Project Gradle File

buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.0'
    }
}

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

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

App Gradle File

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.example.hhs.haberler"
        minSdkVersion 15

        vectorDrawables.useSupportLibrary = true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

There is a bug for Android Studio. I guess your PC's language is Turkish. If you write "androidTestApi" include "androidTestImplementation" to your gradle file, Android Studio gives WARNING like this:

WARNING: Configuration 'androidTestApi' is obsolete and has been replaced with 'androidTestİmplementation'. It will be removed at the end of 2018. For more information see: http://d.android.com/r/tools/update-dependency-configurations.html Affected Modules: app

Pay attention to the strong text at Warning. There is uppercase İ inside androidTestİmplementation, because of your PC's language is Turkish and Turkish have uppercase İ in their alphabet.

So if you replace androidTestImplementation with androidTestİmplementation, problem will be solved.

Or set your PC language as English :)
