extra backslash added in the column values in the genarated sql file from generateChangeLog using maven Liquibase

After generating an sql file from updateSql goal along with generateChangeLog in maven I can see an extra backslash added in the column values of the table. I have figure it out that I can prevent this by using CDATA but I am not able to find any property in liquibase maven that I can use with the goal to avoid the issue.

Original Value of the Column :

http(s)?://([\da-zA-Z.-]+).([a-zA-Z.]{2,6})([/\w .-])/?(\?)?.*$

Value after UpdateSql goal :

http(s)?:\/\/([\da-zA-Z\.-]+)\.([a-zA-Z\.]{2,6})([\/\w \.-])\/?(\?)?.*$

Please let me know if there is solution to use it in maven plugin with liquibase.
