You should not mention version for your spring-data-jpa. Spring-boot parent dependency will resolve that automatically.

Instead of this:

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-jpa</artifactId>
    <! -- <version>2.0.2.RELEASE</version>  comment or remove this line -->
</dependency>

Update: You are using spring-boot-starter-parent version 2.2.4 and different spring-data-jpa version, that's why getting error.
