Hadoop is going towards maven from ant in branch-0.23 and trunk. As of now, some of the modules like MRv1 have to be mavenized though. Ant builds won't be supported in branch-0.23 and trunk. The artifacts produced by the ant and the maven build should be more or less the same. There is no point in using ant, unless there is a specific reason for using it.

Here are the different maven options for building Hadoop.
