I honestly have no idea what's going on. I searched on google and didn't find any answer that would help me, I even put it in chatgpt and also nothing.

if necessary I can commit my code and make it available here for you guys, to try to run.

I googled and didn't find anything relevant.

Mixing jars from different versions. Remove the `spring-beans` dependency. — M. Deinum, Jan 09 '23 at 06:17

The problem is your dependencies which break things.

TL;DR: Remove the spring-beans dependency as that is incompatible with your setup.

Explanation:

You are using Spring Boot 2.7.7 which uses Spring 5.3.x. You have however includes spring-beans for version 6.0.3 which is incompatible with Spring Boot 2.7.7 (it is required/used by Spring Boot 3.0.x).

Remove that dependency as that will already be pulled in by the other dependencies. Which makes me wonder why you decided to include this in the first place?

I'm also wondering why I put this there. But I took it and it worked, thank you very much — Gabriel Menezes, Jan 09 '23 at 12:54
