javax.persistence not included in spring data jpa?

I just created a maven project with this dependency

<dependency>
            <groupId>org.springframework.data</groupId>
            <artifactId>spring-data-jpa</artifactId>
            <version>2.2.1.RELEASE</version>
        </dependency>

but I realized that all these classes are not found:

import javax.persistence.*

so I have to change the dependency to 

 <dependency>
                <groupId>javax.persistence</groupId>
                <artifactId>javax.persistence-api</artifactId>
                <version>2.2</version>
            </dependency>

which I find it weird because last update is from Aug 21, 2017

there is no spring dependency that includes javax.persistence ????

In sprint boot 3, javax.persistence has to be replaced with jakarta.persistence.

Spring Data JPA itself isn't an implementation of the JPA specification. It is an abstraction built on top of JPA that requires a JPA implementation, typically Hibernate, to function. The JPA implementation provides the javax.persistence classes. For this reason, with a dependency on org.springframework.data:spring-data-jpa alone, the javax.persistence classes will not be on the classpath.

If you're using Spring Boot's Data JPA starter (org.springframework.boot:spring-boot-starter-data-jpa), it has dependencies on both Spring Data JPA and Hibernate. Hibernate then has a dependency on the javax.persistence API which makes its classes available to your application's code.
