'[TestNG] Couldn't find the testng.xml in the jar file, running all the classes' error while running test on AWS Device Farm - maven

Question

I am trying to run a test suite on AWS device farm, It is a Maven project, I get the following error on the device farm Parsing result document: [TestNG] Couldn't find the testng.xml in the jar file, running all the classes.
While creating the zip for AWS device farm from Maven I get the following warning:
[WARNING] The POM for org.testng:testng:jar:5.14.3 is invalid, transitive dependencies (if any) will not be available, enable debug logging for more details.
I have the latest version of testng and surefire plugin nothing seems to help. any help on this one will be much appreciated.
My pom.xml is as follows:

Answer 1

You need to add the testng.xml to the root of the -tests.jar file created. To do this put it in the src/test/resources directory to take advantage of the super pom configuration. Alternatively, you can create some testResources tags to reference where the testng.xml is at currently.
Hope that helps
