Based on the exception, it looks like ant could not connect(Connection refused) to your tomcat server.

Double check that tomcat has the manager webapp running and that ant is connecting with all of the correct information.

Tomcat, by default, does not have any manager web-app users enabled. You'll need to uncomment a user and give them a manager role in the tomcat-users.xml, found in $TOMCAT_HOME/conf.

That user, along with their password is then used by ant to connect to it.
