jar run error

[crnfan21]

Hi.

I tested build and run as indicated in the README, and it was successful.

But now, when I try to run the built jar directly through 'java -Djava.security.manager=allow -jar "C:\dev\maestro\maestro-server\build\libs\maestro-server.jar"', the following An error occurs. Could you please help?

@crnfan21 I think the built jar is not an uber jar packed with all dependencies so getting this class not found issue. Can you try ./gradlew bootRun to see if there is any issue?

[crnfan21]

./gradlew bootRun runs well without any other issues and the API is called normally.

Also, I confirmed that the dependency is included in the jar.

Or maybe I did something wrong?

@crnfan21 seems to be related to this issue: spring-projects/spring-boot#31853
Ctrl+c will lead another class not found error

Likely, we need to bump springboot to 3.x to solve it.

[crnfan21]

It was confirmed that the jar was successfully executed in version 3.x. thanks!

Thanks @crnfan21 for the confirmation. I will link the issue to #8 and then close it.
