How do I set labels using the clone issue post-function from Script Runner?

Question

This may be an extremely noob question but how do I set a label in the Additional issue actions?  I can see how to set specific fields, but I can't see the method for labels (I tried the custom field script, but that didn't work either).

I have been bashing my head against the wall for days with this exact problem.

Big Thanks.

A small problem with Rambanams code is, that the issue doesn't exist at the time the additional issue actions are executed. The following slightly modified code works:

import com.atlassian.jira.issue.label.Label
import com.atlassian.jira.issue.label.LabelParser

def labels = new HashSet<Label>()
labels.addAll(issue.labels)
labels.addAll(LabelParser.buildFromString("NewLabel"))
issue.setLabels(labels)

the following code we use in java, so you can convert to groovy import com.atlassian.jira.issue.label.Label; import com.atlassian.jira.issue.label.LabelParser; import com.atlassian.jira.component.ComponentAccessor; import com.atlassian.jira.issue.MutableIssue; MutableIssue mutIssue =ComponentAccessor.getIssueManager().getIssueObject(issue.getKey()); Set labels = new HashSet(); labels.addAll(mutIssue.getLabels()); labels.addAll(LabelParser.buildFromString("New Label")); mutIssue.setLabels(labels);
