我们在Android Studio中创建了一个新项目，但我们的应用程序未运行。（我们拥有最新版本的Android Studio和SDK）

您可以在下面查看错误消息：

Unable to resolve dependency for ':app@debug/compileClasspath': Could not resolve com.android.support:appcompat-v7:28.0.0-rc02.

您可以在下面检查Build.gradle（放置在项目根目录中）：

    // 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:3.1.4'


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

    allprojects {
        repositories {
            google()
            jcenter()
        }
    }

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

问题出在哪里？我们该怎么解决？
