Problems while using ANT for creating HTML (junit style) report - file

Question

I am trying to generate an HTML/Junit Style report for the jMeter tests by using ANT. I have created a build file for this and have done all the pre-requisites like:
set the required variables like java home, ant home, path variables; put the ant build file and the required .jmx file (for jmeter execution) in a folder and calling "ant" command pointing at the same folder.
I tried calling the ant build file by giving commands as ant and ant -Dtest="Sample Workload Script".
The issue i get is that when i run this commands it reaches to the point of executing the test plan and then gives a java platform error (as shown in attached image) and stops the build. Any pointers to what might be causing this?
Java Platform Error when running the ANT Build file
I read somewhere that the ANT version may not be compatible with java 1.8. Speaking of which i am using Ant 1.9.7 and java 1.8.73
My build file:
<?xml version="1.0"?>

Sample build file for use with ant-jmeter.jar
See http://www.programmerplanet.org/pages/projects/jmeter-ant-task.php
To run a test and create the output report:
ant -Dtest=script
To run a test only:
ant -Dtest=script run
To run report on existing test output
ant -Dtest=script report
The "script" parameter is the name of the script without the .jmx suffix.
Additional options:
-Dshow-data=y - include response data in Failure Details
-Dtestpath=xyz - path to test file(s) (default user.dir).
N.B. Ant interprets relative paths against the build file
-Djmeter.home=.. - path to JMeter home directory (defaults to parent of this build file)
-Dreport.title="My Report" - title for html report (default is 'Load Test Results')
Deprecated:
-Dformat=2.0 - use version 2.0 JTL files rather than 2.1

Answer 1

Update "jmeter" section of your build.xml file as follows:
<jmeter
jmeterhome="${jmeter.home}"
testplan ="${basedir}/${test}.jmx"
resultlog="${basedir}/${test}.jtl"
jmeterlogfile="${basedir}/jmeter.log"> <!-- add this line to enabled logging-->
Re-run your test and look into jmeter.log file under your C:\workspace\CPT folder - it should contain enough troubleshooting information so you will be able to find out the cause. If you have problems interpreting the log file - add it to your question.
