Re: Optional dependencies

[ir. ing. Jan Dockx]

Ok, but in the original mail, Jochen talks about the requirements of his _users_, not of the developers of the main project. And users of his users need those dependencies transitively …

The optional tag is *only* for the purposes of transitive
dependencies. It's not really intended for use in a real Maven build.

Frankly, I have no idea ;-). I knew the tag existed, but have no
experience with it yet, although I do recognize your problem (see
http://cvs.peopleware.be/training/maven/maven2/dependencies.html,
Issues). I briefly talked with Vincent Massol during JavaPolis (hi
Vincent -- nice chat), and he wasn't aware of this tag either.
Furthermore, I can't find any real documentation on this tag. It seems
like "somebody" saw the issue, added the tag, and left it there? I
hoped you would report back with some experience though ;-).

What is particularly puzzling to me, is how the <optional /> tag
interacts with the dependency scopes.

Have you tried the <optional /> tag for the dependency?

Thank you. To be honest, I wasn't aware of this tag.

Reading through the docs, I do, however, believe, that it is a partial
solution only, isn't it? I'd prefer a solution where Maven
automatically detects the presence or absence of some classes and
performs the required steps.
