I am using this regex :^(.*regression|.*regress).$* in Jenkin UI under Branch Specifier. This idea is to make any GitHub branch containing name "regression" or "regress" example should match

origin/regression
regression
origin/MOBILE-XXXX-regression-NNNNN
regress
MOBILE-5364-regress
/feature/MOBILE-XXXX-regression-NNNNN ** and perform build or git hook trigger from any such branch. However I am getting this error when I pushed form branch "MOBILE-XXXX-regression"

java.lang.IllegalArgumentException: Invalid refspec refs/heads/:^(.regression|.*regress).$:refs/remotes/origin/

What am I doing wrong or how do I specify the regex in under Branch Specifier to get such matches to work?
