How to manage Maven third party jars
When you find yourself the need to load third party jars into Maven repository,
there are few steps you normally do to test it out. You first install them
locally into $HOME/.m2/repository, and then create your project pom that
list those dependency. When things look good, then you deploy into your own
hosted repository. The following scripts will help you perform these tasks.

Tip

If you have lot’s of jars under a group, it’s more conveninent to create
an extra pom that list these dependency and install/deploy it into the repository
as well. And then your project would only need to include one dependency
with <type>pom</type>.

# Install local jar files into Maven repository. The artifact name would be same
# as the filename minus the extension.

# Usage:
# # Print as maven dependency used in pom file
# mvn-install.sh mygroup 1.0.0 lib/*.jar
#
# # Install jar files into local maven repo
# RUN_TYPE=install mvn-install.sh mygroup 1.0.0 lib/*.jar
#
# # Deploy jar files into remote maven repo
# export REPO_URL=http://localhost/nexus/content/repositories/thirdparty
# RUN_TYPE=deploy mvn-install.sh mygroup 1.0.0 lib/*.jar
#
# Capture command arguments and options
