Maven exec with multiple system properties

Question

I'm trying to run mvn exec with multiple system properties...it works ok with one but not with two for some reason.

e.g. This works fine

mvn  -Dlocation=c:\tmp  exec:java -Dexec.mainClass="MyClass"

This doesn't work

mvn  -Dlocation=c:\tmp  -Djava.library.path=c:\zeromq\ exec:java -Dexec.mainClass="MyClass"
