Artifact upload to nexus using curl

nexus_upload.sh

# nexus 2.x
# Assuming you run this command against the directory the jar sits in
#
# r - repository
# hasPom - whether you are supplying the pom or you want one generated. If generated g, a, v, p, and c are not needed
# e - extension
# g - group id
# a - artifact id
# v - version
# p - packaging
# c - classifier (optional, not shown in examples above)
# file - the file(s) to be uploaded. These need to come last, and if there is a pom file it should come before the artifact
