How do I add a label in post function using scriptrunner?

[Nicole Murphy]

I tried using both scripts on https://answers.atlassian.com/questions/307827 but neither were successful. When adding the script, the error says "cannot find matching method...". Has anyone been successful with this? Thank you!

"cannot find matching method..."

That's all about error or is there something else? Seems to be something more.

Try to debug both scripts in a script runner - works for me as well.

The API may have changed since that answer. As Aleks said, the useful part of the error you get is in the "...". 

[Nicole Murphy]

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.label.LabelManager
  
def user = ComponentAccessor.jiraAuthenticationContext.getUser()
  
LabelManager labelManager = ComponentAccessor.getComponent(LabelManager)
def labels = labelManager.getLabels(issue.id).collect{it.getLabel()}
labels += 'new_label'
labelManager.setLabels(user,issue.id,labels.toSet(),false,false)

The error I get is:
"Static Type Checking -Cannot find matching method: com.atlassian.jira.issue.label.LabelManager#setlabels(com.atlassian.jira.user.Ap
 java.lang.Long, java.util.Set , boolean, boolean). Please check if the declared type is right and the method exists"

The exact script I'm getting this error on is below (the code block above didn't work for some reason):
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.label.LabelManager

def user = ComponentAccessor.jiraAuthenticationContext.getUser()

LabelManager labelManager = ComponentAccessor.getComponent(LabelManager)
def labels = labelManager.getLabels(issue.id).collect{it.getLabel()}
labels += 'new_label'
labelManager.setLabels(user,issue.id,labels.toSet(),false,false)

Hm... Which JIRA version do you use? Maybe it is old enough and do not have this method

[Nicole Murphy]

6.4.6

[Aleks Yenin (Polontech)]

Yes, there is difference. In JIRA 7 method signature is 

setLabels(ApplicationUser remoteUser, Long issueId, Set<String> labels, boolean sendNotification, boolean causeChangeNotification)

but in 6.4.6

setLabels(com.atlassian.crowd.embedded.api.User remoteUser, Long issueId, Set<String> labels, boolean sendNotification, boolean causeChangeNotification)

Try to replace last string this way:

labelManager.setLabels(user.getDirectoryUser() ,issue.id,labels.toSet(),false,false)

[Nicole Murphy]

that did the trick! Thank you so much!

Hello,

This code creates a "labels" , not a specific custom field with label type..

How can I set value in a custom field (with label type)

Thanks,

Daniel

@Nicole The code snippet by you above does not add new labels in the LABEL table, instead it updates the existing record in LABEL table.

Any update from your side for same?
