Spring native: Built image fails to run straight out of the box

[Haarolean]

Hi,

I haven't touched spring-native for a few years, and it seems to be broken even more than it used to be.

While trying to solve other related problems, I tried to run a demo app from scratch, which failed drastically.

Set up:

1. start.spring.io
2. maven, boot 3.1.0, java, jar, 17
3. dependencies: graalvm, configuration processor, devtools, lombok, jpa, validation

Outcome:

1. Jar runs fine
2. Native image doesn't:

 :: Spring Boot ::                (v3.1.0)

I tried using spring-core 6.0.10-SNAPSHOT as has been suggested here, with no luck.
I have published the sources so you can save some time to reproduce the issue: here

Related: #32918, but with java, not kotlin.

It sounds like your application hasn't been AOT-processed, perhaps because it was not built with the correct command. Did you use ./mvnw native:compile -Pnative as described in the HELP.md file of the project generated by start.spring.io?

Hi Andy, thanks for your swift reply.
Indeed, I tried to rebuild the image again, the same way with mvn clean package -Pnative, but couldn't reproduce this anymore.
Got a lot of frustration with trying to get native images working, probably haven't paid enough attention after fighting with this for days.
Thanks again!
