What about Maven Antlib?
After reading all the rants about Maven vs Ant and the Maven Sucks/Doesn't Suck posts of late (JavaLobby, Howard Lewis Ship, Don Brown and others) I'm wondering why everyone seems to suggest using Ivy, yet no one ever mentions the Maven Ant Tasks subproject.
Maven's Ant Tasks provides all the dependency management features of Maven but without the heavy weight change in process normally associated with the full Maven setup.
It would seem that the Maven Ant Tasks provide a sweet spot between a full conversion, I just don't see why its never recommended.
I use the maven ant libs in qwicket and javabot. I think they're great. I get my trans deps without all the ... stuff that comes with maven. The only thing really missing is the project file generation and I'm working on fixing that.
