Custom field in Jira that turns working days into a number

[Matthew_Schulz]

I'm trying to create a custom field that calculates the number of working days in the Sprint the current issue is in, but I'm a little stuck. 

I'm on Jira 7.13 Server

I've created two custom fields to get a timestamp of the start/end of a Sprint:

Start date of a Sprint

End date of a Sprint

Here's the code: 

import com.atlassian.jira.component.ComponentAccessor

import java.sql.Timestamp
import java.time.DayOfWeek

// the name of the custom fields to compare
final String dateCustomFieldName = "Start date of a Sprint"
final String dateCustomFieldName2 = "End date of a Sprint"

def dateCustomField = ComponentAccessor.customFieldManager.getCustomFieldObjects(issue).findByName(dateCustomFieldName)
def dateCustomField2 = ComponentAccessor.customFieldManager.getCustomFieldObjects(issue).findByName(dateCustomFieldName2)
if (!dateCustomField) {
log.info "Could not find custom field with name $dateCustomFieldName"
return null
}

if (!dateCustomField2) {
log.info "Could not find custom field with name $dateCustomFieldName2"
return null
}

if (!issue.getCustomFieldValue(dateCustomField) || !issue.getCustomFieldValue(dateCustomField2)) {
return null
}

def customFieldDate = (issue.getCustomFieldValue(dateCustomField) as Timestamp).toLocalDateTime().toLocalDate()
def customFieldDate2 = (issue.getCustomFieldValue(dateCustomField2) as Timestamp).toLocalDateTime().toLocalDate()

if (!customFieldDate2.isBefore(customFieldDate)) {
return null
}

def weekend = EnumSet.of(DayOfWeek.SATURDAY, DayOfWeek.SUNDAY)
def workingDays = 0

while (customFieldDate2.isBefore(customFieldDate)) {
if (!(customFieldDate2.dayOfWeek in weekend)) {
workingDays += 1
}

customFieldDate2 = customFieldDate2.plusDays(1)
}

workingDays

Here's the error I'm getting:

2019-09-20 10:44:38,325 ERROR [runner.ScriptFieldPreviewRunner]: ************************************************************************************* 2019-09-20 10:44:38,325 ERROR [runner.ScriptFieldPreviewRunner]: Script field preview failed for field that has not yet been created org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object 'Tue Sep 10 14:40:42 PDT 2019' with class 'java.lang.String' to class 'java.sql.Timestamp' at Script326.run(Script326.groovy:26)

Any help would be much appreciated!

Thanks,

Matt

I copied your script exactly into my environment and only changed the name of the 2 fields to use 2 of my date fields. It works just fine.

That error seems to imply that one of the 2 custom fields is not actually a "date picker" or "date time picker" field, but instead, a free text field populated with a text rendering of the date value.

If those fields are indeed text fields, then you need to add some code to parse that text into a date based on the localization used to generate the date string

[Matthew_Schulz]

Using a "Date picker" worked, but unfortunately, the two Fields are custom "Date Time" Fields and the code is not working.

These two fields are custom "Date Time" fields. 

Start date of a Sprint

End date of a Sprint

Would it just be easier to get the Sprint start/end right in the cose instead of trying to get a custom field?

[Peter-Dave Sheehan]

Are those two fields custom scripted fields? 

If so, just change the "searcher" for those custom fields to "Date Time Range Picker"

[Matthew_Schulz]

They are custom scripted fields, but there is no option to change the "searcher". Am I missing something? This is for a Server instance.

[Peter-Dave Sheehan]

You have to do this from the Custom Field page in Jira. There is a shortcut from the scripted field list screen.

Ok, I've found it and changed them. But it's still giving me the error...

I appreciate your help so far! This has been a very tough one to crack for me.
