Maven 2/3 job don't expand variable in rootpom

[Gianluca Chiodaroli]

Even if i found a issue here 
https://issues.jenkins-ci.org/browse/JENKINS-5885 i still have the error:

ERROR: No such file 
C:\Jenkins\jobs\MotFis-Test\workspace\test\$AMBIENTE\DOM\pom.xml 

The variable is defined because i use it in svn checkout

Any advice?

Thanks 
Gianluca
