While using Java File method, Jenkins is searching for the existence of file in master even though we run under slave node

import groovy.json.*

def commonJsonFile
def commonJsonText

node('NETSEC_PUNE_SUSE11_X86_1') {
   commonJsonFile = new File('/temp/dev/pipeline/common.json')
   commonJsonText = new JsonSlurper().parseText(commonJsonFile.text)
}

println(commonJsonText.pspopensslv6.gitproject);
