Unfortunately, even for packages like apache-commons the artifact id
that upstream uses is rather inconsistent (e.g. commons-vfs-*project*),
not to mention the group id.

Image the generic java codemonkey, firing up his ide and setting up some
libs. He just discovered (I don't know how, because codemonkeys usually
don't care about their OS) that fedora ships apache-commons-logging and
wants to use it in his project. So he does installed it and wants to
link it to his ide now (possibly even the javadoc dir, to use something
like inline api highlighting). And now you really think, that the he is
aware, that the jar is name after the maven artifact id. Our codemonkey
has enough trouble finding the right directory and changes are that he
never even heard about maven.
You have to keep in mind, that packaging java-libs is way more than your
own use-case.

In an ideal world, I'd totally agree. Unfortunately, projects using
maven poms tend to have rather strange interpretation of what artifact
id to expect from a dependency and I really don't like the idea of
providing a symlink for every broken dependency in a pom file.

Well, we already dropped the versioned symlinks. I can't remember any
votes against (But to make sure, you could look at the meeting log).

It was decided to drop versioned symlinks to the javadoc directories. We
ran into that a couple of times.

As I already explained, I don't think that a good idea. That'd cause
more trouble for a dumb user who's not able to help himself, but a tiny
bit less trouble for a someone, who's totally capable of. I know how
much *I* hate it, when I install packages and have to query the files
because the binary name is different from the package name.

Of course, I'm not actually going through all packages and fixing just
symlinks. Your right, that'd be a waste of time. But since I have to
touch all apache-commons specfiles because I have to get rid of maven2,
it's not a big deal to clean them up, too. I was just asking myself, if
we still need those symlinks, asked the guys in #java-devel, and wanted
to be polite and inform other java-developers. In fact, I think typing
this email took way more time that actually doing the work :)
