错误:无法解析':app @ debugAndroidTest/compileClasspath'的依赖项:无法解析junit:junit:4.12

我创建了一个新的android项目，它显示了已构建的错误

我尝试了现有的答案

• 无法解决:com.android.support :appcompat-v7 24.0.1

我的gradle文件的依存关系部分

Dependencies section of my gradle file

 dependencies 
    {
       implementation 'androidx.appcompat:appcompat:1.0.2'
    testImplementation 'junit:junit:4.12'

    }

我不明白这是我的第一个项目.

I do not understand it is my first my project.

我的项目gradle是

My Project gradle is

// 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:3.4.1'

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

allprojects {
    repositories {
        jcenter()
        maven {
            url 'https://maven.google.com'
        }
    }
}

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

我的应用gradle是
