Why spring.io generate pom without version?

Question

I'm new to springboot and using spring.io to create project in order to create microservices.

When creating a project using spring.io website, a pom is created with all the relevant dependencies but versions are not added. Should I add the versions myself looking the maven repository jar (all jars include versions on them)?

Who is the parent? can I see it? I just want to make sure auto upgrade won't happened. — user2304483, Jun 29 '21 at 05:44
The thing defined by the `parent` tag in your pom. I strongly suggest you read on how maven works as you seem to be lacking in that area. — M. Deinum, Jun 29 '21 at 05:57

All dependencies (and configurations) are managed by Spring Boot. The parent of the project you generated with Spring Initializr has the parent set to spring-boot-starter-parent:

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.5.2</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

The parent of spring-boot-starter-parent is spring-boot-dependencies which defines all dependency versions.

Therefore you don't need to specify any versions of the starter dependencies or their dependencies manually.

Please take a look at The Spring Boot Starter Parent on Baeldung for a quick overview.
