Passing properties to Maven based build

We are successfully passing the RTC buildLabel property in our Maven builds.

In the .pom, we define:

<properties>

      <buildNumber>1.0-SNAPSHOT</buildNumber>

</properties>

also

     <version>${buildNumber}</version>

(Note: the "N" in buildNumber tag is a capital "N", it just doesn't display that way)

In the build definition for our release builds, on the "goals" in the Maven tab, we add:

-DbuildNumber=1.0-${buildLabel}

Without the parameter, the developers still run SNAPSHOT buiilds, using 1.0-SNAPSHOT.  Our release builds are created with the RTC build label as: MyBuild-1.0-20130402-1000.jar

What doesn't work for us was adding the property in the Properties section, as this doesn't seem to work like it did running ANT builds.

Unfortunately, mvn doesn't have a command line option for passing a properties file (which is the mechanism JBE uses to pass properties to Ant), and the Maven participant in JBE does not generate -D's for every property.
