Groovy Post function on Create transition can't set Date custom field value

Based on the references online, I have come up with this Groovy Script. I have a custom field called 'Expected Start Date' which is a required field filled in by the Jira user. Based on this Start Date, I have written a post function Groovy script that is used to update another custom field in Jira 'Ship Date' by calculating 3 business days prior to Expected Start Date. When I run the Groovy script from Script Runner, I see the following error. Appreciate your help.

ERROR: javax.script.ScriptException: java.lang.ClassCastException: com.atlassian.jira.issue.ModifiedValue cannot be cast to java.util.Date

Jira date fields typically accept or java.sql.timestamp objects or calendar.

The format of date being displayed on UI is configured in administaration settings.

I suggest to try throw either of the three to the field and see what sticks :)


I actually tried myself as I encountered same question in my development

Custom fields of types Date and Datetime accept objects/

Here is the code that I tested in Scripted field that works :

import java.util.*
import java.sql.Timestamp
import com.atlassian.jira.ComponentManager
import com.atlassian.jira.issue.CustomFieldManager

def customFieldManager = ComponentManager.getInstance().getCustomFieldManager()
def dt = new Date() //now
def date = new Date(0) //1970
def ts = new Timestamp(dt.getTime()) //this will work for built-in field DueDate!
def cf_date = customFieldManager.getCustomFieldObjectByName("cf_date") //alright! I know it's a stupid name for CF :)
def cf_datetime = customFieldManager.getCustomFieldObjectByName("cf_datetime")
issue.setCustomFieldValue(cf_date, dt)
issue.setCustomFieldValue(cf_datetime, date)
return issue.getCustomFieldValue(cf_datetime)

Thank you, Alexey for offering help. Thanks to Jamie, who helped me in fixing my script. My script works fine when I manually run it from scriptrunner but not when I insert it into the post-function at 'Create' in the workflow.

Moving the post-function further down below all the post-functions worked.

Please refer this post , there is a simliar script available

Moving the post-function further down below all the post-functions worked.
