Can you please try
1) without -DarchetypeGroupId.
2) with a clean local repository

Thanks

Thanks for the tips, Raphaël.
(Andreas reported this issue for my benefit)

I cleaned everything out of my local repository, and then ran just: "mvn archetype:generate"
....and became the exact same error message as before...
java.lang.NoClassDefFoundError: org/apache/commons/lang/StringUtils

I have attached the output from running "mvn -X archetype:generate"

Btw, we are using an Artifactory server to "proxy" and cache all repository requests.

Shouldn't there perhaps be:

<dependency>
<groupId>commons-lang</groupId>
<artifactId>commons-lang</artifactId>
</dependency>

....in the org\apache\maven\archetype\archetype-common\2.0-alpha-3\archetype-common-2.0-alpha-3.pom?

Without it, Maven isn't retrieving the commons-lang repository, which I assume is needed for the archetype to run!?

PS, if I add the dependency to the pom, archetype:generate progresses further, but still has some serious issues. But.... archetype:create works!

Here i tried with a fresh repository.
I use nexus to proxy repositories.
Could it be an artifactory bug?
Is it working without any proxy?

Raphaël, thank you for your help!
Turns out, it is infact indirectly an "issue" with Artifactory. (Without any repository proxy, everything works perfectly for me as well

Artifactory is working as designed, but the Velocity 1.5 POM is faulty. Problem described here:
