How to run NUnit Runner in Atlassian Bamboo with NUnit 3

I used NUnit Runner in Atlassian Bamboo (latest version) with NUnit 2 but after upgrading to NUnit 3 it is no longer working. It appears something changed with the command line in NUnit 3. Anyone know how to make NUnit 3 work in Atlassian Bamboo? Or could the NUnit devs consider backward compatibility for this breaking change?

I get the following error:

Invalid argument: -xml=TestResults-Rev_02f5436a0a70cd539bd3b77218fb48cbe3262954-Build_12.xml

Thank you
