When using publish over ssh plugin the nested variables are not expanded in the fielad remote directory and exec command. I have the following situation.
MY_VAR=3.q.$BUILD_NUMBER.r.$BUILD_ID
when i put into the field remmote directory
mydir-$MY_VAR
on the server is created directory
mydir-3.q.$BUILD_NUMBER.r.$BUILD_ID

but when i put into the field remote directory
mydir-3.q.$BUILD_NUMBER.r.$BUILD_ID
on the server is created directory
mydir-3.q.168.r.150201
given that BUILD_ID is 150201
and BUILD_NAMUBER is 168
