It doesn't matter which plugin you use to set the property. What does matter is when the property substitution takes place. It normally happens in the very beginning of the Maven build when the pom is read, before the build lifecycle is executed and way before your plugin is executed. So you need the plugin (where you use the created property) to do an "extra" property substition step as you describe in your code.
