Just consider the technical aspects of the problem : how do you identify
the non-released package ? By a timestamp ? How do you associate this
timestamp with some source ?

For an external user having some problem with your project, just because
there is something wrong in this non-release package, how do you think
someone can help debugging the problem ? How do you track the exact code
associated with this non-released package?

This is just common sense, and anyone who has already worked with
non-released/non-trackable packages know exactly what I mean.

Otherwise, if common sense is not enough, you can probably use
http://incubator.apache.org/guides/releasemanagement.html#best-practice-dependencies,

" (Where appropriate) check the that the application is built against
the correct versions"

Now, assuming the dependencies are Apache projects, then you can't
release them into your own project release, if they aren't themselves
released, per http://www.apache.org/dev/release.html#what :

" Under no circumstances are unapproved builds a substitute for releases."

and again, from
http://incubator.apache.org/guides/releasemanagement.html#best-practice-dependencies
:

"dependencies should comply with the current apache policy"


By depending on a non-released component, you are breaking these rules,
AFAICT.

IMHO, leveraging common-sense should be enough...
