# Simple script to check consistency of the shaded artifact. It is by no means perfect,
# but it's better than nothing.
#
# Quick usage:
#
# nite@nitebug : ~/netconf/netconf/shaded-exificient-jar $ mvn clean install
# nite@nitebug : ~/netconf/netconf/shaded-exificient-jar $ mkdir x
# nite@nitebug : ~/netconf/netconf/shaded-exificient-jar $ cd x
# nite@nitebug : ~/netconf/netconf/shaded-exificient-jar/x $ rm -rf * && unzip ../target/shaded-exificient-jar-*-SNAPSHOT.jar && ../check_jar.sh .
