It’s always interesting to see what your work looks from the outside, from the view of that people that you don’t know, not biased from your relationship.
I was reading Sylvain Wallez Spring switching to Maven entry, where he exposes that Maven is too much black magic for him and prefers Ant. I think there’s a common basic mistake in his explanation, and I have already seen it in other places. If you are already an Ant user, of course it will look crystal clear after the years you have spent learning it, your opinion is also biased (not that I’m saying my opinion is not biased, that of course it is).
When talking about Ant you should also think about that first time user, that junior developer that haven’t left the IDE, and tell him that it’s easier to use Ant than Maven.
