How to write a groovy validation simple script runner for valid email regular expression

[Pradeep Kumar]

I want to validate that when user enters valid email address or not in a custom field.

we are seeing below error.

Please help.  Code below.

import com.atlassian.jira.ComponentManager
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.issue.fields.CustomField
import com.atlassian.jira.component.ComponentAccessor

CustomFieldManager customFieldManager = ComponentAccessor.getCustomFieldManager()
//def customFieldManager = ComponentManager.getInstance().getCustomFieldManager()
def myFieldValue = issue.getCustomFieldValue(customFieldManager.getCustomFieldObjectByName("Client Submitter Email"))

/* Set debugging level */
log.setLevel(org.apache.log4j.Level.DEBUG)

def regexStr = /[a-zA-Z0-9.'_%+-]+@[a-zA-Z0-9.-]+\.[A-Za-z]{2,4}/

log.debug("myFieldValue: " + myFieldValue)

if (myFieldValue == null || myFieldValue == "") {
return true
}

try {
if (myFieldValue.matches(regexStr)){

log.debug("Valid email address: " + myFieldValue)
return true

} else {
log.debug("Invalid email address" + myFieldValue)
return false
}
}
catch(err) {
log.debug("Please enter valid email address")
log.debug(err.getMessage())
return false
}

/* Re-set debugging level */
log.setLevel(org.apache.log4j.Level.WARN)

Assuming 'myFieldValue' is a string then I guess you've ran into a known issue with static type checking in ScriptRunner not always being accurate. More info here. With that in mind I would simply ignore this error and see if the actual validator works.

Did this script actually work?
