# Script pulls newest version of this repository (via './git_pull_recursive.sh') and
# executes Maven's 'clean' and 'install' command. The latter is done using
# the pom.xml file the path of which is either provided via argument to this script or, if no
# argument is provided, is assumed to be located at './transceiver_framework/pom.xml'.
#
# If a pom.xml location is provided via argument, it must match the pattern './<name>/pom.xml', where
# '<name>' is some subfolder in the project root folder (represented by '.'). 
#
# Afterwards, a fat jar containing the project (as defined via the aforementioned pom.xml)
# and all its dependencies should be present at './<name>/<name>/<name>.jar'.
