There is a maven plugin that solves this particular problem: directory-maven-plugin

It will assign the root path of your project to a property of your choosing. See highest-basedir goal in the docs.

For example:

  org.commonjava.maven.plugins
  directory-maven-plugin
  0.1
  
    
      directories
      
        highest-basedir
      
      initialize
      
        main.basedir
      
    
  

Then use ${main.basedir} anywhere in your parent / child pom.xml.
