[Les Hazlewood][les] has an objective summary of why he eventually came around to deciding that Maven is a better overall solution then Ant + Ivy. This is an evolution in thought process that we, [Sonatype][sonatype], often see in enterprises and Les has two blog entries that illustrate this evolution perfectly.
[Maven 2 vs Ant+Ivy: Our selection process]: This entry gives Les' original perspective on Maven and the process by which he originally decided to choose Ant + Ivy.
[Maven 2 vs Ant+Ivy: Revisited]: This entry gives Les' new perspective and why his enterprise team, and the Apache Shiro project, have chosen Maven.
> I now firmly believe that Maven 2 is a better build and project management tool than Ant+Ivy. I was wrong.
> Yep, I said it. I’m man enough to admit when I’ve made mistakes and that I’ve learned from my experiences. And this is coming from the guy that wrote a (still popular) OnJava article for Ant in the enterprise.
> Overall, life with Maven is good. I’m glad that I was able to swallow my pride, really give it a chance, and in turn reap the benefits. I haven’t used Ant in over a year since switching, nor have I ever felt the need to go back.
We hope this perspective helps potential enterprises save time when looking for a build and release infrastructure.
