I have the feeling that Ivy [1] can help us regarding our dependencies.
The advantages include:
- central repository (eventually, see below)
- dependencies need not be in SVN (eventually, see below)
- transitive dependency management (i.e. we say we need X, if X depends
on Y it will come automatically)
- conflict management between dependencies (easier upgrading of
dependencies)
- much easier integration testing. We can have different build
configurations for release, development and test, release using fully
tested jars, development using latest releases and/or milestones
- easier continuous integration testing
- full dependency reports (i.e. better developer docs)
- modules could be resolve via dependencies and could have dependencies on its
own.
The disadvantage is that, as far as I am aware, no developers here other
than myself know ivy (and I'm still learning). However, Ivy docs are
great [2]
Here is a possible plan:
1 - Create a lenya only repo in SVN (Forrest has started something that we can
reuse).
although wherever possible we will use the IVY repo and the
Maven2 repo
2 - We modify our build files to use IVY (Forrest has some set of generic
build files that are intended to be extended by project specific build
files.)
3 - We make sure it works
4 - We move the entries in our repo to the IVY repo (We need to enter
into a dialogue with IVY devs to see what is happening with regards an
official Apache repo)
The end result will be a build system that uses three repos:
The lenya/forrest one for any jars we have customised but are not yet
available in the main project releases (i.e. we have something in the
patch queue)
The official IVY repo (whatever that turns out to be)
The official ASF Maven repo
wdyt?

Aren't you concerned that Ivy is too "young", has too few developers
supporting it, and that it is still in incubator status? It seems a
little risky.
