Hi,
Just to let you know, we are planning to remove the ant build system in the next couple of weeks from *trunk* which is now *Narayana(http://www.jboss.org/narayana)*.
The ant build system will continue to work and be maintained on the 4.x branch: http://anonsvn.jboss.org/repos/labs/labs/jbosstm/branches/JBOSSTS_4_15_0_Final/
