Re: [m2e-users] Archetype Selection Using m2eclipse

[Igor Fedorenko <igor@xxxxxxxxxxxxxx>]

By default m2e recognizes three sources of archetypes (a.k.a "Archetype
Catalogs").

1. archetypes defined in ${user.home}/.m2/archetype-catalog.xml, these
are referenced as "Default Local" drop-down choice in archetype selection UI

2. If I am not mistaken, "Internal" are archetypes defined in
archetype-common-2.0-alpha-4.jar!/archetype-catalog.xml (2.0-alpha-4 is
the archetyper version shipped with m2e).

3. archetypes that are listed in nexus/maven indexes of repositories
visible to m2e. I think nexus populates this information by scanning
deployed artifacts for hosted repositories and from remote indexes for
proxy repositories, but you need to double-check on nexus users mailing
list to be sure.

It is also possible to configure additional local and remote archetype
catalogs via workspace. Documentation [1] linked from the preference
page provides more information about archetype catalog format.
