Re: [m2e-users] nested modules

[Benson Margulies <bimargulies@xxxxxxxxx>]

Igor, I get this idea that there are people out there who have never,
ever, done a conventional checkout of their projects into the file
system. Their projects are sitting in source control in some
arrangement that does not correspond to the aggregate/parent
structure, and they have become accustomed to taking advantage of the
'classic' eclipse mechanism of grabbing projects  from wherever and
checking them out into the workspace.

I've never personally seen the attraction of this, but I think it is
what drives all the upset email about the SCM integration.
