Let's see if this fixes the ability for mvn to fully-execute the release without failing on pushing the Git tags:

<!-- Release -->
<plugin>
<artifactId>maven-release-plugin</artifactId>
<version>2.0</version>
<configuration>
<autoVersionSubmodules>true</autoVersionSubmodules>
</configuration>
</plugin>

...works in the SHRINKDESC project just fine.
