java.lang.NullPointerException: groupId was null

[Otto Kolsi]

Hi!

I'm testing Continuum 1.1 beta 1 with Ant projects. So far it seems to 
work fine. I noticed following minor issue and thought to mention.

I haven't yet created any Project Groups, so my Ant project is in the 
Default Group. The Release functionality is new so without configuring 
it, I just tried it.

When Release is pressed, Continuum gives error (see below). NullPointers 
are generally a bad thing, so even though Release should not work 
without proper configurations.. maybe instead of NullPointer a more 
informative error message could be given?

Best Regards,
--
