I'm creating basic spring boot application as in [this guide](https://spring.io/guides/gs/spring-boot/)

If I download their [completed-guide-code](https://github.com/spring-guides/gs-spring-boot/archive/main.zip), I get the `complete` folder to run and test app.

But if I do practice as [start from scratch](https://spring.io/guides/gs/spring-boot/#scratch), install prequisite, go to [start.spring.io](https://start.spring.io) and config, generate starting project, create web app, create app class, and go to step `Run the Application`, I cannot find the folder `complete` as in guide, so I can't run and test app. Maybe I should run some build command to create it? So how to create it?
