Why springboot application stops immediately from IDEA but works with mvn spring-boot:run

Question

When i run a springboot application with command "mvn spring-boot:run" then it starts tomcat and keep running but same application when started from Intellij from main class "com.example.demo.DemoApplication" then it shuts down immediately with below logs. How to run it from IDE:

Answer 1

I had the same issue some time ago with IntelliJ - for me removing of .idea and .iml folders and after that re-importing the project to IDE helped.
