Did you ever figure out what was wrong here? I'm running into the same issue
now with the alpha-3 plugin.

Hey Raphaël, I added the settings to my settings.xml as you described and
ran archetype:create-from-project. The POM file referenced 2.0-alpha-2.

So I added the following to my parent POM, and the resulting POM under
target/generated-sources/archetype had 2.0-alpha-3 in them.

Unfortunately, I now get the following error when rerunning
archetype:create-from-project:

I tried including commons-lang in POMs to see if that would help, but no
luck.
Thanks

Hi John,
This feature is provided by the 2.0-alpha-3 version of the Archetype
plugin. This version is not yet released.
But you can try the last snapshot by adding a repository to apache
snapshot [1].
1. The goal to call from the project directory (or parent in case of a
multi module) is 'mvn archetype:create-from-project'.
2. Then go to the target/generated-sources/archetype directory and see if
the generated archetype is correct.
install the archetype in your local repository by calling 'mvn install' as
usual.
3. Then go to a fresh directory and call 'mvn archetype:generate
-DarchetypeCatalog=local'.
Step 3 may don't work because repositories defined in profiles in the
settings.xml file are recognised only when maven is called in a project's
directory. One may try to use the apache's snapshot repository as mirror
of central (not tested).
Another workaround i see is compiling the plugin from the sources.
Please share your experience of using the plugin afterward.
Thanks,
Raphaël
