Jason van Zyl commented on MNG-624:
-----------------------------------
Ralph, is there some example projects in the branch somewhere? I just want to
see what you see as the layout.
I see it as a set of projects on disk, that are all connected, chaining upward
to the parent where it has the implicit Super POM parent, or is not connected
to its parent on disk. If this is the case then the version element in parent
references wouldn't even be required as all the projects are connected. Once
you have that contained set then the one version is either specified explicitly
or as a property. I always assumed in this case it's all or nothing in that
people wouldn't be checking out leaf node projects and trying to build them.

> currently, you have to specify the parent version when extending which makes
> a project stand alone very easily, but has the drawback of being a
> maintainance problem when you start development on a new version. Tools can
> help, but it would be nice not to have to rely on them.
> One alternative is to allow the parent version to be omitted, and when it is
> it is assumed you want the latest. The parent is used from the reactor or the
> universal source directory. IT may also be read from a LATEST in the
> repository though this is contentious - it may be better to simply fail in
> that environment and require builds be in a known checkout structure for
> building individual projects.
> This also introduces the need for tool support to populate the version on
> release and deployment for reproducibility.
