import hudson.model.*
import jenkins.model.Jenkins


def timer = 5000 //5s timer
def counter = 12 * 10 // 10 minutes reruns


for (i = 0; i <counter; i++) {
   def q = Jenkins.instance.queue
  println("$i / ${counter}")
	q.items.findAll { def causes = it.getCauses()
                     	try {
                 			return causes[0].getShortDescription() == 'Branch indexing'
                        } catch (e){}
                	}.each { 
      					
						q.cancel(it.task)
					 }
  sleep(timer)
}

This script checks each 5s for 10 minutes,
if there are builds from branch indexing in the queue and cancels them
