Can someone please validate the below script to fetch date value from a different field ?

[Aisha M]

import com.atlassian.jira.component.ComponentAccessor

import com.atlassian.jira.issue.Issue

Issue issue = issuedef customFieldManager = ComponentAccessor.getCustomFieldManager()

// the dependent custom field

def dateACF = customFieldManager.getCustomFieldObjectByName("Due Date")

// get the value of the Due Date custom field

def dateAValue = issue.getCustomFieldValue(dateACF) as Date

// build the new date

def dateB = Calendar.getInstance()

// copy to the new date the value of the Due Date custom field

dateB.setTime(dateAValue)

return dateB.getTime()

When I run this , I get an error as "java.lang.NullPointerException"

Can someone please help me out. Thanks

You should add logging to your script and see in the logs, what object gives you a NullPointerException. It could be done like this

import com.atlassian.jira.component.ComponentAccessor

import com.atlassian.jira.issue.Issue

Issue issue = issuedef customFieldManager = ComponentAccessor.getCustomFieldManager()

// the dependent custom field

def dateACF = customFieldManager.getCustomFieldObjectByName("Due Date")

log.error("dateACF: " + dateACF)

// get the value of the Due Date custom field

def dateAValue = issue.getCustomFieldValue(dateACF) as Date

// build the new date

def dateB = Calendar.getInstance()

// copy to the new date the value of the Due Date custom field

dateB.setTime(dateAValue)

return dateB.getTime()

@Alexey Matveev Thank you for your reply Alexey. I tried your script above and got the below error,

groovy.lang.MissingMethodException: No signature of method: org.codehaus.groovy.jsr223.GroovyScriptEngineImpl.issuedef() is applicable for argument types: (com.atlassian.jira.issue.managers.CachingCustomFieldManager) values: [com.atlassian.jira.issue.managers.CachingCustomFieldManager@52e105aa]

It is strange error. I can not see a reason why it would be caused by the code. Could you try again?

@Alexey Matveev Tried running it again. Unfortunately getting the same error. 

[Alexey Matveev]

Yes, I got it. Try like this:

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.Issue

def customFieldManager = ComponentAccessor.getCustomFieldManager()

// the dependent custom field

def dateACF = customFieldManager.getCustomFieldObjectByName("Due Date")

log.error("dateACF: " + dateACF)

// get the value of the Due Date custom field

def dateAValue = issue.getCustomFieldValue(dateACF) as Date

// build the new date

def dateB = Calendar.getInstance()

// copy to the new date the value of the Due Date custom field

dateB.setTime(dateAValue)

return dateB.getTime()

[Alexey Matveev]

And the correct script would be like this:

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.Issue

// get the value of the Due Date custom field

def dateAValue = issue.getDueDate() as Date

// build the new date

def dateB = Calendar.getInstance()

// copy to the new date the value of the Due Date custom field

dateB.setTime(dateAValue)

return dateB.getTime()

The problem is that Due Date is not a custom field and you should get the value of the field by issue.getDueDate()
