在我的测试计划中，我有以下脚本，

import groovy.json.JsonSlurper;

def completeFetchedStudyNameFromResponse = []; 
1. upto(vars.get('studyNameFetched_matchNr') as int, {
  index ->
  completeFetchedStudyNameFromResponse.add(vars.get('studyNameFetched_' + index));
});

String tempToBeExcludedStudyName = vars.get('excludeStudyName');

def toBeDeleteStudy = [];
def studyNameNeedToExcludeFromDeletion = new JsonSlurper().parseText(tempToBeExcludedStudyName);

def filteredStudyName = completeFetchedStudyNameFromResponse.findAll {
  studyName ->
    studyNameNeedToExcludeFromDeletion.every {
      keywords ->
       studyName.contains(keywords)
    }
}
def bdConverter = new JsonSlurper();
def responseBDTemp = prev.getResponseDataAsString();
def responseBD = bdConverter.parseText(responseBDTemp);
def resultStudyUUIDCollector = [];
def parsedResultBD = responseBD.accounts;

filteredStudyName.each { studyNameFew ->
  resultStudyUUIDCollector.add(responseBD.accounts.find { account -> account.name == studyNameFew }.uuid)  
}

vars.putObject("myList", resultStudyUUIDCollector);

这个脚本在JMeter 5.5和Java 17中运行得很好，但是当我在JMeter 5.4和Java 1.8中运行这个脚本时，出现了以下错误：

2023-06-16 11:34:58,180 ERROR o.a.j.e.JSR223PostProcessor: Problem in JSR223 script, StudyName_Processer
javax.script.ScriptException: org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
Script1.groovy: 1: unable to resolve class groovy.json.JsonSlurper

有没有什么方法可以在不升级的情况下用较低版本的Java运行相同的程序？
