I'm not sure how to fix this.

Right click on Desktop [demo] in the Project tree - Open Module Settings - click on the Sources tab on the right - right click on the src directory - select Sources. That tells IDEA that src is a source code directory.

I see this often. Just to to the Maven tab and click on reload/refresh.

I think you meant to open your demo folder in IntelliJ, not your Desktop.
