Affects Version/s: 0.8
Fix Version/s: 0.9-rc-1
I have posted following issue in TestNG JIRA issue tracker:
The response I received was:
This looks like a problem with Gradle, not TestNG.
This error message is printed when you run TestNG on a testng.xml file that uses <suite annotations="">, which is no longer supported, since only the standard JDK annotations are supported now.
I'm guessing Gradle is generating a testng.xml file with this incorrect attribute and the fix should be to simply not generate that attribute in the XML file any more.
I suggest you send a link to this issue on the Gradle list and see what they have to say.
