 properties file could be used the specify $ so it can be interpolated in
 <developerConnection/> but you couldn't use a properties file to specify the

  Notice that the 5 URLs from the model (<<<project.url>>>, <<<project.scm.connection>>>, <<<project.scm.developerConnection>>>,
  <<<project.scm.url>>> and <<<project.distributionManagement.site.url>>>) have a special inheritance handling:
