Not exactly what I was trying to say :)

There is (and should be) a full source release for all release
artifacts (for that particular version) based on the standard Maven
-sources and related artifacts in the release repository. Together
these contain all information needed to be able to setup development
in any IDE and yes it will require some manual labor or a shell script
or whatever.

But IMHO you cant attack that with a ease-of-use argument cause nobody
(outside this particular audit case) will ever do it like that in real
world development. If so there would be support for it already and if
Apache still thinks it should be supported by all means let's start a
mavenrepository2myIDE project. I personally think it's a bad idea
though, because you still will end up with a filesystem layout mapping
to different tags/version. Again, look at Apache Felix or Apache Sling
and try to imagine how a full source release for these types of
project would look like when mapped to SCM and then think of the
usefulness...

Anyway, while I was typing Karl more or less made the same argument
already... let's merge back to one thread :)
