Errors I don't understand using xUnit plugin and Qt C++

[Rick Frank]

I'm using Jenkins with Qt and C++ and xUnit plugin

When building source with QMake, I get the following xml Files files created

 generatedJUnitFiles\d63f3c66-bc18-440d-a701-d95c0d0ebaaa\xUnit.Net\TEST-b4dc9b2c-83db-401f-a81c-bc7888527387.xml

which has only 

<?xml version="1.0" encoding="UTF-8"?>

and the system tries to read these files and errors.

I also get what I expect are "correct" files

\generatedJUnitFiles\39c08746-60d7-475b-b69f-81509e16c5cf\QTestlib\TEST-57a7ffb4-aa61-4f4e-9da6-50d28ece65e5.xml

which has what looks like valid data 

How do I stop producing the empty xml files?

Thanks

What are the xUnit.Net files?
