BUILD FAILED in 27s
Error: Gradle task assembleDebug failed with exit code 1

FAILURE: Build failed with an exception.app

app构建失败，原因：Gradle 在构建过程中无法下载所需的 androidx 依赖，解决方案：排查根目录下的build.grandle文件，看看allprojects==》repositories里面引用的镜像地址是否支持下载项目运行所需的依赖，你可以尝试替换掉你的镜像地址，以下是我的配置的镜像地址，仅供参考：

allprojects {
    repositories {
        google()
        mavenCentral()
        maven { url 'https://maven.aliyun.com/repository/public' }
    }
}

改写镜像地址后再次运行，成功运行到模拟器中，没有报错。
