Bulk delete groups in JIRA using Scriptrunner

Sid_jdplcb

Due to some syncing error, we have over 2000 groups created in JIRA (all of those groups are empty). I am trying to find a scriptrunner code to bulk delete all of them. Any help would be appreciated.

Thanks

Something along these lines might work (untested)

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.crowd.embedded.core.util.StaticCrowdServiceFactory

def crowdService = StaticCrowdServiceFactory.crowdService
def groupManager = ComponentAccessor.groupManager

groupManager.getAllGroups().findAll {
   groupManager.getDirectUsersInGroup(it).size() == 0
}.each{
   crowdService.removeGroup(it)
}
