New project - new to kotlin, spring and maven

#1

Hi, I’m setting up a demo project using this tutorial https://spring.io/guides/tutorials/spring-boot-kotlin/
This is my first time using Kotlin and Spring Boot. I’m running into a couple issues getting everything going. The first is in IntelliJ any package import having to do with spring says Unresolved reference.

springerror

The project runs from cmd line using Maven. I can go to localhost:8080. Except now I’m unable to stop the project. Error unable to shutdown gracefully. I’ve tried finding process ID with netstat but not working. Ctrl-c does nothing as well.
