控制台右边报错：

Unable to resolve dependency for ':app@debug/compileClasspath': Could not find any version that matches com.android.support:appcompat-v7:29.+.

翻译：无法解决':app@debug/compileClasspath'的依赖项:找不到任何与com.android.support:appcompat-v7:29.+匹配的版本。

解决该问题的方法：降低compileSdkVersion的SDK版本，一般改为27以下就好了。

路径：app\build.gradle

编译成功
