How do I delete unused screens in JIRA Server via API?

Paul Tiseo_bvbmic

I have multiple screens unassociated to any workflow or screen schemes. How do I delete these via the JIRA API (not REST)? I have ScriptRunner. I am able to delete WorkflowSchemes and Workflows because I found the WorkflowManager and WorkflowSchemeManager classes in the docs. But, there seems to be no ScreenManager? Does it have another name?

Also, once I have a list of screens, how do I check if it isn't in a screen scheme or workflow? (As in the https://example.com/secure/admin/ViewFieldScreens.jspa)

Hey Paul

The following script will remove the screens that are not assigned to a scheme or in a workflow. 

Is not fully tested so I would suggest to get a backup first.

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.fields.screen.FieldScreenManager
import com.atlassian.jira.issue.fields.screen.FieldScreenSchemeManager
import com.atlassian.jira.workflow.WorkflowActionsBean

def fieldScreenManager = ComponentAccessor.getComponent(FieldScreenManager)
def fieldScreenSchemeManager = ComponentAccessor.getComponent(FieldScreenSchemeManager)

def allScreensIds = fieldScreenManager.getFieldScreens().collect {it.id}
def screenSchemes = fieldScreenSchemeManager.fieldScreenSchemes

def screenIdsWithScheme = []
screenSchemes.each {
def items = fieldScreenSchemeManager.getFieldScreenSchemeItems(it).collect {it.fieldScreen.id}
    screenIdsWithScheme << items
}

def workflowBean = new WorkflowActionsBean()
def screenIdsWithWorkflowAction = []

ComponentAccessor.workflowManager.workflows?.each {
    screenIdsWithWorkflowAction << it.allActions?.findResults { workflowBean.getFieldScreenForView(it)?.id ?: null }
}

def screenIdsInWorkflows = screenIdsWithWorkflowAction.flatten().unique()
def screensNotAssociatedToScheme = (allScreensIds - screenIdsWithScheme.flatten() - screenIdsInWorkflows)

screensNotAssociatedToScheme?.each {
log.debug "${fieldScreenManager.getFieldScreen(it).name} is not associated with any Screen Scheme or workflow and will be removed"
    fieldScreenManager.removeFieldScreen(it)
}

Let me know how this went.
