Hi,

if you call via Ant script? Why? Special requirement ?
Are you on Windows or Linux ?

Do you call the "mvn.bat" or "mvn.cmd" file ? Do you call the file from 
the distribution ?


Apart from that the property is intended to find the root folder of a 
multi module build where the ".mvn" folder can be located...

See Release notes for more details on it...

Maven-Ant-Task has not been updated for Maven 3.3.X as far as i know...


Kind regards
