The ant tasks for maven are very similar, but I have found them to be

all- and were written with no tests, no reentrancy, and fairly weak
failure modes. Also, Ivy is way better at handling complex dependency
setups, with different paths for different custom tasks, etc. That said,
Maven profiles may achieve something similar.
Just to echo my agreement here. I didn't find the Maven tasks usable
out-of-the-box (perhaps I was using an early version). The effort that
went into creating the tasks appeared to be grudging, at best, and I ran
into several issues early on.
I had to go into the source and add better error reporting, and other
minor modifications.s Also, in order to make them more usable in our
system, I found that I had to wrap the tasks inside friendlier macros.
It was a bit more work than I expected and a hassle, and I was close to
yanking the tasks out at some point and replacing it with Ivy.
Unfortunately, by that time I felt like I'd already had a time
investment and wasn't ready to start from scratch with another tool.
In retrospect, I'd have probably gone with Ivy, since its dependency
management appears to be more robust. The only benefit of going with the
Maven2 tasks that I can think of is that you already have the start of a
pom.xml if your project migrates to using Maven2. The entire process
helped me to gain a better understanding of Maven2 and its configuration
and repositories, which was nice, but I would have rather spent that
time working on real code, instead of finessing the Maven plugin.

The Ivy stuff doesnt need Ant, but the team all use ant, it is an apache
project under ant.apache.org these days, and we may move to tighter
coupling in future.
If you are sticking with Ant, use Ivy.
