Hi,
Some thoughts that I want to share on this thread. Here are the
points we think mainly differentiate maven2 and Ivy.
1. Maven2 is a software project management and comprehension
tool, whereas Ivy is only a dependency management tool, highly
integrated with Ant, the popular build management tool.
2. Ivy heavily relies on a unique concept called configuration.
In ivy, a module configuration is a way to use or to see the
module. For instance, you can have a test and runtime configuration
in your module. But you can also have a mysql and an oracle
configuration. Or a hibernate and a jdbc configuration. In each
configuration you can declare what artifacts (jar, war, ...) are
required. Maven2 on its side has something called the scope. You
can declare a dependency as being part of the test scope, or the
buildtime scope. Scopes are predefined in maven2 and you can't
change that.
3. Ivy let you do whatever you want: use one conflict manager in
one module, another one elsewhere, decide which revision you will
get, you can even plug your own conflict manager if you need to. With
maven2, conflict management is quite simple: the principle is to get
the nearest definition.
4. In Ivy many things can be configured, and many others can be
plugged in: dependency resolvers, conflict manager, module descriptor
parser, latest revision strategy, ...
Maven2 also offers repository pluggability, but not much more as
far as we know. Moreover, repository configuration is much less
flexible than with Ivy: no repository chaining, no way to split
metadata and artifacts in multiple repositories.

Hi Steve,
I'm all for dependency management.
I have only used Maven, do you know of any similarities with Ivy apart
from the obvious dependency management :) ie. repositories etc. guess
I should take a look.
