As much as I disliked Maven 1 , I've come to enjoy and rely on Maven 2.
It's getting things done for me. It's fast. The Maven plugin for Eclipse (that is, an Eclipse Plugin that support Maven, rather than the Maven plugin that generates Eclipse control files) seems to work well, automatically picking up changes to my pom.xml, as well as automatically downloading dependencies. And I'm using it in a tough way, given that I'm also using AJDT on the same projects.
I also think that the new "almost plain text" format is a godsend; it makes it much eaiser to quickly assemble good documentation. I'm trying to write documentation before writing code for Tapestry 5.
Still, maybe 20% of the time, I don't feel that I'm using a tool so much as appeasing a petty god. There's still a number of things I can do easily in Ant that seem to require writing Maven Mojos and plugins to do in Maven.
