Maven pom version inheritance

I have 3 projects Parent,Child,SubChild.

Project Parent pom is as follows:

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.3.3.RELEASE</version>
</parent>

<groupId>mu.parent</groupId>
<artifactId>parent-system</artifactId>
<version>1.0</version>
<packaging>pom</packaging>

....

Project Child pom is defined below and its Parent is defined follows:

<modelVersion>4.0.0</modelVersion>

    <parent>
        <groupId>mu.parent</groupId>
        <artifactId>parent-system</artifactId>
        <version>1.0</version>
    </parent>
    
    <groupId>mu.dummy.child</groupId>
    <artifactId>child-backend</artifactId>
    <name>child-backend</name>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>pom</packaging>

  <modules>
        <module>subChild-app</module>
  
    </modules>


...

Now subChild pom is as follows and the child is defined as parent for subChild :

 <parent>
            <groupId>mu.dummy.child</groupId>
           <artifactId>child-backend</artifactId>
          <version>0.0.1-SNAPSHOT</version>
    </parent>
 <groupId>mu.dummy.subchild</groupId>
    <artifactId>subchild-backend</artifactId>
    <name>subchild-backend</name>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>pom</packaging>

  <dependencies>
        <dependency>
            <groupId>org.project.test</groupId>
            <artifactId>project</artifactId>
       <version></version> --version of parent-system???
        </dependency>

    </dependencies>

Is it possible to get version of parent-system(1.0) in subchild-backend please without hardcoding it?

I asked a similar question a while back and determined that tthe groovy-maven-plugin works for this. See this answer.

You can use CI-friendly versions and write ${revision} for the versions, setting this property in the main pom (from which you build everything).

You need to use the flatten Maven plugin, though, to get proper POMs in the repository.
