Scriprunner code to validate regular expression using Match function

[Priya ThirumalaiKrishnamoorth]

Hi, I need to validate a custom field value. The format is CRQ<0-9>. Total digits have to be 12. I used the below code.

if((issue.customfield_10063.match("CRQ[0-9]{12}")) ||

(issue.customfield_10063 == null)) {

           true

}

else {

       false

}

The script throws error if the field is blank

The scripts accept more then 13 digits as well and does not throw error

How do i ensure that it allows blank or accepts CRQ followed by 0-9 digits of length 12 only?

Hi @Priya ThirumalaiKrishnamoorth ,

here a code that should work :

def value = issue.customfield_10063

return (value == null || value == "") || value ==~ /^CRQ\d{12}$/

Hope this helps,

Fabio
