Actually for the first time, it's better to use:
mvn clean install -Pdep,gwt-admin,setup_postgres

setup_postgres - will copy postgresql datasource file and additional
configuration files to jboss. setup_postgres won't be required until
specific changes to those configuration files is made.

dep - will copy the ear and quartz to jboss deploy folder.
