If you are reading this, you are probably wondering how this
maven repository is laid out. This is not a true maven repository.
Rather, it is a filesystem configured to match the layout of a
maven repository. As such, there is no index page or other
dynamically generated metadata files.

including the repository and dependency in your build script
the artifacts should resolve.

You can also install a maven dependency from the command line like so:
mvn org.apache.maven.plugins:maven-dependency-plugin:2.4:get
  -DgroupId=[group id]
  -DartifactId=[artifact id]
