Testng listener to comply with Apache Ant JUnit XML Schema - junit

Question

As part of a testng automation test suite I would like to automatically push results from jenkins to testrail. I currently have this plugin installed on my jenkins server: https://github.com/jenkinsci/testrail-plugin
The read me states the output must comply with the junit schema: https://github.com/windyroad/JUnit-Schema/blob/master/JUnit.xsd
I have reference How do I get one junit report from TestNG for all my test cases? and added
<listeners>
<listener class-name="org.testng.reporters.JUnitXMLReporter"></listener>
</listeners>
to my listeners; however, this does not seem to create a file in the correct format as this causes jenkins to fail with the message :
Uploading results to TestRail.
Error pushing results to TestRail
Posting to index.php?/api/v2/add_results_for_cases/236 returned an error! Response from TestRail is:
{"error":"Field :results cannot be empty (one result is required)"}
Build step 'TestRail Plugin' marked build as failure
Finished: FAILURE
I am wondering if there is a different listener I should be using instead.
Thank you for the help.

Answer 1

I used the xsd file that was shared in the question to create a TestNG reporter that complies with the xsd.
To consume this reporter, please add a dependency as below
<dependency>
<groupId>com.rationaleemotions</groupId>
<artifactId>junitreport</artifactId>
<version>1.0.0</version>
</dependency>
This reporter makes use of the service loader approach to wire in itself. So it doesn't need to be added explicitly via the <listeners> tag (or) the #Listeners annotation.
