What we do here, is define a parent-POM which holds the version-number. All
child-projects to this POM, must at least define the version for the
parent-project, but from there on, you don't need to define them anymore.
Example:
<project>
<parent>
<groupId>my.group</groupId>
<artifactId>parent-artifact</artifactId>
<version>0.0.1-SNAPSHOT</version>
</parent>
<artifactId>artifact</artifactId>
<dependencies>
<dependency>
<groupId>${groupId}</groupId>
<artifactId>another-artifact</artifactId>
<version>${project.version}</version>
</dependency>
</dependencies>
</project>
This project references the parent over a version, inherits that version as
its own version and even uses it to reference another child-project as a
dependency (with that same version again).
Now, if you were to use the release-plugin, you'd never have to change
anything here (unless you explicitly want to use another version of a
parent/dependency).
