jenkins pipeline 读取json 文件

groovy 解决方案（失败）

import groovy.json.JsonSlurper
def json = new JsonSlurper().parse(new File("${env.WORKSPACE}/allure-report/widgets/summary.json"))

结果报fileNotFoundExecption

java.io.FileNotFoundException: xxxxx/allure-report/widgets/summary.json (No such file or directory)

jenkins 自带读取文件api (成功)
