This sounds like it's a regression caused by the changes made for
NMAVEN-142 (which rolled into NMAVEN-119).
Is there a way to test the various scenarios? (I usually use it through the UI which would be hard to test, but is it separated into some library methods that could be tested?)
Since it now has a problem if the assembly info file is missing, I wonder what happens if the file is pressent, but there is no company name element?
