Agreed, to some extent. But have a look at Chapter 8 in our book to see
how I organize library directories such that I don't simply have an
unstructuring dumping ground called "lib". Its an organized tree of 3rd
party libraries allowing me to easily switch between library versions by
simply saying -Dstruts.version=1.1b2 for example.
While I haven't (yet) gone to the level of defining a version property,
this is what is spec'ed in the properties file - one or more "jars",
including version information in the path (usually).
libs. I know that I'm tired of having yet another copy of
jaxp/xalan/xerces downloaded with every new open source project I'd like
to use.
Have a look at Maven. It maintains a 'lib.repo' directory and
automatically pulls down dependent libraries if you don't have them.
I'd already pulled CruiseControl (and gotten it into the environment) to
use as a CI engine, when I revisited Maven (prompted by a Javaworld
article, maybe?) Maven looks really nice -- maybe it'll be worth the
effort to switch over...
P.P.S: Seems to be rearing its head again in the J2EE space (include all
the dependencies in the war/ear jar).
Yes, I have issues with the WAR/EAR thing too - I've not had success
deploying some dependencies in one place in an EAR and it seems some are
needed in both the EAR and sub-WAR's too.
I think J2EE suffers more from DD-hell... deployment descriptors, that is. :)
No argument there -- but since we're all going to be generating them with
XDoclet (Ch. 14!) now, there will be a lot less pain! (My compatriot is
pushing this one - I've never used it, but is has to be better than
maintaining all those descriptors by hand!)
