Ivy Configurations when pulling from a Maven Repository Part I
I heard about Ivy (http://ant.apache.org/ivy) some time ago, but never really took the time to look into it. After all, I had Maven, and that's what we were using at work. So I really had no incentive to look into it. As I'm sure many of you have found there are some issues with Maven. With all the things it does well, there are a few things where it really falls flat on it's face. How about transitive dependencies for example? Bane of my Maven experience.
The standard project layout is very nice, but at the same time it is a hindrance if, for whatever reason, you need to go against it. As most of my readers have seen I'm pretty well entrenched in the Seam camp. Seam does not play well with Maven, or maybe it's Maven that doesn't play well with Seam (Embedded JBoss to be specific, but others have found ways around this [http://www.google.com/search?q=seamtest+maven&hl=en, https://issues.jboss.org/browse/JBSEAM-2371 to name a few]).
For those that have been using Seam with Maven are familiar with not being able to run their Seam tests easily with Maven, unless you know to put your test scoped dependencies first in the pom. There are some other issues I have with Maven, but this is not a post about how much Maven sucks. You can google for those, there are a lot of them; back to Ivy.
A few months ago my friend Dan Allen blogged about dependancy management in a seam-gen project with Ivy, see his post for a decent intro to Ivy. In his code download he was unable to setup the dependencies needed for testing his project. In this post I'm going to explain why Dan ran into problems, the relationship between Maven scopes and Ivy configurations, as well as provide an updated version of his Ivy-ized seam-gen download.
