I also tried by myself with the tutorial from jetbrains: https://kotlinlang.org/docs/tutorials/spring-boot-restful.html

[Czar]

and your Application file?

[avolkmann]

@SpringBootApplication
class Application

fun main(args: Array<String>) {
    runApplication<Application>(*args)
}

[avolkmann]

again, same as in the template

[Czar]

hmm let me check something...

[Czar]

I've just copy pasted your code and it works.
Where do you get the error?

I always get told that Application is final

I mean what tells you that?

[Czar]

looks correct, too

[avolkmann]

Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: @Configuration class 'Application' may not be final.

[avolkmann]

When I run the app

[Czar]

via IntelliJ or bootRun task?

[avolkmann]

IntelliJ

[Czar]

try bootRun to make sure that the setup is in fact correct with gradle and then we'll see what we can do about IJ

[avolkmann]

yeah bootRun works

[Czar]

Ok, then:
1) Ctrl+Shift+A -> refresh all gradle projects <enter>
2) When the 1) finishes: Ctrl+Shift+A -> Rebuild Project
when that finishes try to run again

[Czar]

The listed shortcut is standard for Linux/Windows, it's the shortcut for "Find action", in case you're on a different OS or hotkey schema.

[avolkmann]

Wow that really did it. Thanks a lot !

[Czar]

You have to do that when you change something in gradle, so that IJ picks up the changes.

[Czar]

oh, most of the time (if you didn't replace any used dependencies) you can skip the rebuild part.
In fact I only do the rebuild if something doesn't work after the refresh.

[nfrankel]

when using maven
just enable auto-import
and forget about it
(just saying 😉)

[Czar]

same with gradle, but auto-import is not ideal especially when you're actively changing build configuration, you don't want IJ to constantly try to refresh half-configured project.
For small projects, yeah, auto-import is ok.

[nfrankel]

ok
