springboot package javax.persistence does not exist

I am following this tutorial https://spring.io/guides/tutorials/rest

At the first step when I added class Employee by copying from the tutorial, it says package javax.persistence does not exist

I added dependencies given in the tutorial. I generated the initial project using spring initializr as described in the tutorial. My pom is below:

</project>

SDK selected in the IDE is here

Even in this simple step this is not working.

I have tried maven reimport, maven clean-install, invalidate caches and restart. None of these worked.

Should I add a dependency? Isn’t spring data starter enough?

This is really hard.

>Solution :

This guide is written in a version of spring-boot < 3.x it mean that all javax. imports was moved to jakarta. And you are using <version>3.1.4</version>
It mean that every imports also from guide will be

FROM

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;

TO:

import jakarta.persistence.Entity;
import jakarta.persistence.GeneratedValue;
import jakarta.persistence.Id;

Also I suggest you to have a look at preparing-for-spring-boot-3-0
