grails validation using regex

Hi i am trying to validate a Date for mm/dd/yyyy patterns using regex in command object constraints.

regex:

^(((0?[1-9]|1[012])/(0?[1-9]|1\d|2[0-8])|(0?[13456789]|1[012])/(29|30)|(0?[13578]|1[02])/31)/(19|[2-9]\d)\d{2}|0?2/29/((19|[2-9]\d)(0[48]|[2468][048]|[13579][26])|(([2468][048]|[3579][26])00)))$

grails constraints

static constraints = {
        date(blank:false)
        date(matches:"^(((0?[1-9]|1[012])/(0?[1-9]|1\d|2[0-8])|(0?[13456789]|1[012])/(29|30)|(0?[13578]|1[02])/31)/(19|[2-9]\d)\d{2}|0?2/29/((19|[2-9]\d)(0[48]|[2468][048]|[13579][26])|(([2468][048]|[3579][26])00)))$")
}

i am getting following error 

unexpected char: '\' @ line 61, column 47.
^(((0?[1-9]|1[012])/(0?[1-9]|1\d|2[0-8])

it is not accepting the \

You need to escape "\" and "$" signs:

"^(((0?[1-9]|1[012])/(0?[1-9]|1\\d|2[0-8])|(0?[13456789]|1[012])/(29|30)|(0?[13578]|1[02])/31)/(19|[2-9]\\d)\\d{2}|0?2/29/((19|[2-9]\\d)(0[48]|[2468][048]|[13579][26])|(([2468][048]|[3579][26])00)))\$"
