Please avoid abbreviations like, “pb,” which is not clear to all readers.

We can only help if we have the full details. Which module is that package in? It appears not to be in Java21SE. Do you have Java® installations? Do you have EE classes installed anywhere?

You probably just need to rename your imports to jakarta.persistence.

Is it because the other project is using Spring Boot 2 and it accepts java.persistence?

A different project will have different dependencies, and consequently different imports can be resolved.

javax.persistence versus jakarta.persistence has nothing to do with the JDK itself, it's indeed the dependencies that determine which of the two you need. Spring Boot 2.x used javax.persistence, but in Spring Boot 3 they moved to jakarta.persistence. This is basically just a newer version of the same thing, but due to licensing (or something like that) the javax. package prefix could no longer be used. The javax. package prefix is owned by Oracle, and Java EE is now no longer owned by Oracle but renamed to Jakarta EE.
