I'm using the following script in an scripting field but for the first status. And it is not working.
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.history.ChangeItemBean
def changeHistoryManager = ComponentAccessor.getChangeHistoryManager()
def inProgressName = "In Progress"
List<Long> rt = [0L]
def changeItems = changeHistoryManager.getChangeItemsForField(issue, "status")
changeItems.reverse().each { ChangeItemBean item ->
def timeDiff = System.currentTimeMillis() - item.created.getTime()
if (item.fromString == inProgressName) {
rt << -timeDiff
}
if (item.toString == inProgressName) {
rt << timeDiff
}
}
def total = rt.sum() as Long
return (total / 1000) as long ?: 0L
It just works if in progress is not the first status.
