How to lock version Dependency/Plugin with Maven archetype

Question

I'm currently working on how to fix version of dependencies and plugins with maven archetype. Here is how my archetype-resources/pom.xml look like.

    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>${spring-version}</version>

The archetype-metadata.xml look like that:

<requiredProperties>
 <requiredProperty key="spring-version">
   <defaultValue>2.1.5.RELEASE</defaultValue>
 </requiredProperty>
</requiredProperties>

Then i added the property to the archetype.properties file

spring-version=2.1.5.RELEASE

When I create an project from this archetype it will correctly show the 2.1.5.RELEASE version. However this method seems not the best when you have a lot more dependencies or it is not the proper manner on how to lock version?

Dependency Management

The dependency management section is a mechanism for centralizing dependency information. When you have a set of projects that inherits a common parent it's possible to put all information about the dependency in the common POM and have simpler references to the artifacts in the child POMs. The mechanism is best illustrated through some examples. Given these two POMs which extend the same parent:

Project A:

<project>
  ...
  <dependencies>
    <dependency>
      <groupId>group-a</groupId>
      <artifactId>artifact-a</artifactId>
      <version>1.0</version>
      <exclusions>
        <exclusion>
          <groupId>group-c</groupId>
          <artifactId>excluded-artifact</artifactId>
        </exclusion>
      </exclusions>
    </dependency>
    <dependency>
      <groupId>group-a</groupId>
      <artifactId>artifact-b</artifactId>
      <version>1.0</version>
      <type>bar</type>
      <scope>runtime</scope>
    </dependency>
  </dependencies>
</project>

Project B:

<project>
  ...
  <dependencies>
    <dependency>
      <groupId>group-c</groupId>
      <artifactId>artifact-b</artifactId>
      <version>1.0</version>
      <type>war</type>
      <scope>runtime</scope>
    </dependency>
    <dependency>
      <groupId>group-a</groupId>
      <artifactId>artifact-b</artifactId>
      <version>1.0</version>
      <type>bar</type>
      <scope>runtime</scope>
    </dependency>
  </dependencies>
</project>

These two example POMs share a common dependency and each has one non-trivial dependency. This information can be put in the parent POM like this:

<project>
  ...
  <dependencyManagement>
    <dependencies>
      <dependency>
        <groupId>group-a</groupId>
        <artifactId>artifact-a</artifactId>
        <version>1.0</version>

        <exclusions>
          <exclusion>
            <groupId>group-c</groupId>
            <artifactId>excluded-artifact</artifactId>
          </exclusion>
        </exclusions>

      </dependency>

      <dependency>
        <groupId>group-c</groupId>
        <artifactId>artifact-b</artifactId>
        <version>1.0</version>
        <type>war</type>
        <scope>runtime</scope>
      </dependency>

      <dependency>
        <groupId>group-a</groupId>
        <artifactId>artifact-b</artifactId>
        <version>1.0</version>
        <type>bar</type>
        <scope>runtime</scope>
      </dependency>
    </dependencies>
  </dependencyManagement>
</project>

Then the two child poms become much simpler:

<project>
  ...
  <dependencies>
    <dependency>
      <groupId>group-a</groupId>
      <artifactId>artifact-a</artifactId>
    </dependency>

    <dependency>
      <groupId>group-a</groupId>
      <artifactId>artifact-b</artifactId>
      <!-- This is not a jar dependency, so we must specify type. -->
      <type>bar</type>
    </dependency>
  </dependencies>
</project>
<project>
  ...
  <dependencies>
    <dependency>
      <groupId>group-c</groupId>
      <artifactId>artifact-b</artifactId>
      <!-- This is not a jar dependency, so we must specify type. -->
      <type>war</type>
    </dependency>

    <dependency>
      <groupId>group-a</groupId>
      <artifactId>artifact-b</artifactId>
      <!-- This is not a jar dependency, so we must specify type. -->
      <type>bar</type>
    </dependency>
  </dependencies>
</project>

you can do this also for plugins with What is pluginManagement in Maven's pom.xml?
