groovy - JMeter groovy 语言抛出 'unable to resolve class' 但 beanshell 或 java 都可以

Question

我正在使用 JMeter 4.0。下面是我在 JSR223 Sampler 中的一些代码。它在目录中查找并找到特定文件。

//This looks in the test results folder and locates
//the most recent file with the testReport prefix we are looking for

import org.apache.commons.io.FileUtils; 
import org.apache.commons.io.filefilter;
import org.apache.commons.io.filefilter.WildcardFileFilter;
import org.apache.commons.io.comparator.LastModifiedFileComparator;

//show some logging in the jmeter log and in the jenkins console
log.info("=== get Test Results File to Upload ===");
OUT.println("=== get Test Results File to Upload ===");

//put the test_results_path property in a string to make it easier to work with
String dir_path = props.get("test_results_path");
log.info("=== test_results_path === "+dir_path);
OUT.println("=== test_results_path === "+dir_path);
String rpt_pref = props.get("testReport_prefix");
//log.info("=== testReport_prefix === "+rpt_pref);
//OUT.println("=== testReport_prefix === "+rpt_pref);
String rpt_suff = props.get("testReport_suffix");
//log.info("=== testReport_suffix === "+rpt_suff);
//OUT.println("=== testReport_suffix === "+rpt_suff);

//define an empty file
File theNewestFile = null;
try {
   File dir = new File(dir_path);
   //log.info("=== file directory === "+dir);   
   //OUT.println("=== file directory === "+dir);   
   FileFilter fileFilter = new WildcardFileFilter(""+rpt_pref+"*."+rpt_suff+"");    
   //log.info("=== fileName === "+fileFilter);
   //OUT.println("=== fileName === "+fileFilter);   

   File[] files = dir.listFiles(fileFilter);
   if (files.length > 0) {
        /** The newest file comes first **/
        Arrays.sort(files, LastModifiedFileComparator.LASTMODIFIED_REVERSE);
        theNewestFile = files[0];
        String fileName = files[0].getName().toString();
        log.info("=== File to Upload === "+fileName);
        OUT.println("=== File to Upload === "+fileName);
        props.put("varResultsReportFile",fileName);
   } else if(files.length <= 0) {
            /** no files exist **/
            //theNewestFile = ;
            String fileName = "FILE_MISSING";
            log.error("*FAILED to find file for "+vars.get("testApp")+" ===  "+fileName);
        OUT.println("*FAILED to find file for "+vars.get("testApp")+" ===  "+fileName);
        //SampleResult.setSuccessful(false);
        SampleResult.setStopTestNow(true);
        //SampleResult.setResponseData("FILE_MISSING");
        props.put("varResultsReportFile",fileName);
   }

    return theNewestFile;
}
catch (Throwable ex) {
   log.error("*FAILED - Something bad happened", ex);
   throw ex;
}

当我使用 Language = BeanShell 或 Java 运行它时，它运行良好。当我尝试使用 Language = groovy 时，它给了我这个错误:

javax.script.ScriptException: org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
Script16.groovy: 5: unable to resolve class org.apache.commons.io.filefilter
 @ line 5, column 1.
   import org.apache.commons.io.filefilter;
   ^

我已经检查过，我的 lib 文件夹中似乎有 jmeter 4.0 附带的 commons-io.jar 。我将java jdk升级到8_181。我还可以做些什么？现在我将使用 beanshell 运行，但想转换为 groovy，因为这是 jmeter 相对 beanshell 的首选语言

我不知道你从哪里得到这段代码，但它做了一些非常奇怪的事情。即使您解决了所有编译和其他问题，它也不会起作用，因为您的整个测试将停止在这一行:

SampleResult.setStopTestNow(true);

并且不会再进一步​​。

根据前缀和后缀查找最新文件的更简单方法如下:

File theNewestFile = new File(props.get("test_results_path")).listFiles().findAll {
    it.getName().startsWith(props.get("testReport_prefix")) && it.getName().endsWith(props.get("testReport_suffix"))
}?.sort { -it.lastModified() }?.head()
