# The nifi web api is available as a war file but not as a jar file.
# We need to compile patches against the classes in it, so we need
# a jar file.  This shell extracts the class files from the war and copies
# them to target/classes so maven can package them into a jar file.
# The jar is then used as a "provided" dependency for compiling the
# design tool patches
