Optional dependencies
Hi,
are there any recommendations on how to handle dependencies, which
aren't always required?
For example, I am using JDK 1.5 classes in some projects like
javax.xml.Constants, or javax.xml.namespace.QName. For JDK 1.3, and JDK
1.4 users, these are available as dependencies like
geronimo-qname_1.1_spec
However, I wouldn't like to add these dependencies by default. Is it
possibly to enable these only, if required?
Regards,
Jochen

Thanks, read through the docs and this seems to be fine. I was missing
one feature, though, which I have filed as MNG-1910: The jdk element
should allow values like 1.4+.

Create a profile, activated by the jdk, and include the dependency within it.
Cheers,

Optional was not the solution to his original mail (I emailed him
separately about using profiles in this instance).
I just wanted to answer your question about the use of optional.

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.

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.

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