Actually not. Especially the parent is the only place where a variable
can't be used. But in maven the version number of the all artifacts in the same
reactor (collection of maven modules in one build) is usually explicitly
written as the maven-release-plugin takes care of updating all the version
numbers. The only place it tends to have problems with is when referencing
versions in the plugin configuration. That's why I used variables in the
maven-dependency-plugin configuration.
