However, it is more fun to do it again from scratch.
From the menu File, I select the wizard to create a New Spring Starter Project.
A few seconds later, I have my new shiny helloSpring project. I open the project POM (remember that I accepted the default project type, Maven), and I am not surprised to see it reflects the selections I have chosen by the wizard.
To run my hello application, I now go to the Spring Boot Dashboard. By default, you should find this view on the bottom left in your STS window. If missing, you could get it back from Window - Show View
Starting HelloSpringApplication on a555 with PID 8552 Started HelloSpringApplication in 1.348 seconds (JVM running for 1.995)Good. The application worked fine.
