SoapUI Pro Maven Plugin Not Generating Reports

I tried to post this on the board for SoapUI Pro but wasn't able to do so. I'm integrating the SoapUI Pro Maven plugin to a project but it doesn't appear to be generating any reports. I read on this thread

viewtopic.php?f=2&t=3142

that soapui.home needed to be specified. However, where does this property need to be specified?
