Blazemeter running Jmeter script - Problem in JSR223 script, Retrieve Tasks javax.script.ScriptException: groovy.lang.MissingMethodException

I am attempting to run a working jmeter script in blazemeter, but getting the following error where it tries to run my groovy scripts. I am writing trying to access jmeter properties that were set in a previou groovy script.

<JSR223PostProcessor guiclass="TestBeanGUI" testclass="JSR223PostProcessor" testname="Get Tasks to be Added" enabled="true">
            <stringProp name="cacheKey">true</stringProp>
            <stringProp name="filename"></stringProp>
            <stringProp name="parameters"></stringProp>
            <stringProp name="script">

import groovy.json.JsonOutput;

def failureMessage = &quot;&quot;;
def jsonResponse = null;

JsonSlurper JSON = new JsonSlurper ();
JsonOutput JsonOut = new JsonOutput ();

try {
    def numTasksToAdd = vars[&apos;numTasksToAdd&apos;] as Integer;    
    jsonResponse = JSON.parseText(prev.getResponseDataAsString());
    props.put(&quot;tasks&quot;, JsonOut.toJson(jsonResponse.result[0..numTasksToAdd]))
    } catch (Exception e) {
    failureMessage += &quot;Invalid JSON.\n&quot;
    log.info(e.toString());
}
</stringProp>
<stringProp name="scriptLanguage">groovy</stringProp>
</JSR223PostProcessor>

second groovy script

<JSR223PostProcessor guiclass="TestBeanGUI" testclass="JSR223PostProcessor" testname="Retrieve Tasks " enabled="true">
          <stringProp name="cacheKey">true</stringProp>
          <stringProp name="filename"></stringProp>
          <stringProp name="parameters"></stringProp>
          <stringProp name="script">

import groovy.json.JsonSlurper;

JsonSlurper JSON = new JsonSlurper ();

var props = org.apache.jmeter.util.JMeterUtils.getJMeterProperties();

def failureMessage = &quot;&quot;;
def tasks = null;

try {
    
     tasks = JSON.parseText(props.get(&quot;tasks&quot;));

    for (i = 0; i &lt; tasks.size(); i++) {
        
            vars.put(&quot;taskId&quot; + i.toString(), tasks[i].id.toString());
            vars.put(&quot;taskTag&quot; + i.toString(), tasks[i].sourceTag.toString());
        
    }  

    vars.put(&quot;taskCount&quot;, tasks.size().toString());
         
    } catch (Exception e) {
    failureMessage += &quot;Invalid JSON.\n&quot;
    log.info(e.toString());
}


</stringProp>
<stringProp name="scriptLanguage">groovy</stringProp>
</JSR223PostProcessor>

is in my jmeter file, and getting the following error

Solution

  • In order to resolve the compilation failure issue you need to change this:

    var props = org.apache.jmeter.util.JMeterUtils.getJMeterProperties();

    to this:

    def props = org.apache.jmeter.util.JMeterUtils.getJMeterProperties();

    In general you don't even need this line because props shorthand is a pre-defined variable for the JSR223 Test Elements:
