Conceptual Problems with Ant and Maven

ANT

+Build script does not listen to a running target
++Listeners have only a limited amount of events http://ant.apache.org/manual/listeners.html
+Ant extensions like macrodef try to solve DRY but there is a steep learning curve and very specific to Ant.

Maybe the CI server is doing too much?

MAVEN

Conventions and Dependency Management are strengths
