Build failure with Maven 3

With maven 3, build fails.
It seems like that jetspeed-unpack-maven-plugin:2.2.1:unpack doesn't work with maven 3.
Also, it has been recommended to replace "pom.version" by "project.version".

Full stacktraces are like the following (excerpted from the Jetspeed user mailinglist):
