Unable to create Maven project using Archetypes

What I want to do is create a Maven project I can import into Eclipse so I can author some tests against a REST endpoint (cannot use the scenario recorder for that - FireFox REST client is not captured). In doing so I was trying to use a working Maven archetype for Gatling IO 2.0.2.

Since we use Nexus in front of the Maven world I added this to my ~/.m2/settings.xml - which is from older documentation:

excilys Excilys Repository http://repository.excilys.com/content/groups/public

And I use this command:

mvn archetype:generate -DarchetypeCatalog=http://repository.excilys.com/content/groups/public/archetype-catalog.xml -Dfilter=io.gatling:

Per the only current (2014) docs I can find on this blog: http://theholyjava.wordpress.com/2014/04/28/how-to-create-and-run-gatling-2-0-tests/

However, I end up being told nothing matches the filter so I picked a “close match”:

http://repository.excilys.com/content/groups/public/archetype-catalog.xml → io.gatling.highcharts:gatling-highcharts-maven-archetype (-)

Which subsequently fails on me:

ERROR] Failed to execute goal org.apache.maven.plugins:maven-archetype-plugin:2.2:generate (default-cli) on project standalone-pom: The desired archetype does not exist (io.gatling.highcharts:gatling-highcharts-maven-archetype:2.0.0-M3a) → [Help 1]
[ERROR]
[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.

I am a Maven beginner/novice, so please keep it simple.

System Info:

Please properly read the documentation.
http://gatling.io/docs/2.0.2/extensions/maven_archetype.html

All our artifacts are now published on maven central, not on Excilys’ private repository. Don’t specify the catalog, so you use the default one.
