I was following this tutorial: https://www.youtube.com/watch?v=MOCeQYbQPPU&t=2845s
https://github.com/shabbirdwd53/spring-security-tutorial
Inside the project, there are 3 project modules. I had problems opening this project after downloading, in my eclipse, I got a weird amount of packages outside the project folders.
Then I tried to create a maven project spring-security-tutorial, then inside it, I tried to create the OAuth-authorization-server project. But the project folder appears outside of the spring-security tutorial, not inside the spring-security tutorial.
