argument in the Continuum build definition is not passed to Maven

Emmanuel suggested filing a bug for this:
With Continuum 1.1, I have two build definitions for one project - one for hourly builds and the other for a daily full build. We want different email addresses for each build definition. We tried configuring the notifier address in the pom as a property ${smx.project.build.email} and then passing the value as an argument in the Continuum build definition. However, with no mail received we found the log indicates errors below.

Also, if there is a better way for Continuum to handle this, please let me know.
