I’m switching from Eclipse to IntelliJ CE 2024.3.1.1 (but onestly after 10 minutes of usage I’m changing idea)
and I opened a SpringBoot 3.4.1 project create with Spring Initliazr.

As I said, I’m using Spring Boot 3.4.1, Java 21, there isn’t a line of code! I have just some import:

• spring-boot-starter-data (H2 database),
• spring-boot-starter-web,
• h2database,
• lombok (1.18.12)

this is the behavior of the leading IDE for Java and Kotlin (They said…):

If I perform clean install from the IDE maven configuration -> everything goes fine
If I perform clean package from the IDE maven configuration -> everything goes fine
If START my webapp as application from the IDE Run/Debug configuration -> App Start and Shutdown fine (this is the only way to debug the application)
If I perform spring-boot:run from the IDE maven configuration -> Application Starts correctly (as I can see on the log) but when I click the shut down button it returns this error:

I obtain the same behavior if I perform spring-boot:start

Adding spring-boot-devtools is useless: regardless of how the app is started – when I change something – it doesn’t reload.

Finally I see all my application.properties directive gray… and the file is not recognized as Spring configuration file even if I had installed the Spring Assistant plugin.

Why do I get these errors if I try to start the application with maven (3.9.9. Bundled)? The Spring Assistant plugin works only with .yaml files? Or did I do something wrong?
