Creating a Specs Project with Maven

[David Morrow]

I am following the tutorial on creating a Bamboo Specs repo and getting an error consistently.  Is there something I am missing in the process documented here?
https://confluence.atlassian.com/bamboo/tutorial-bamboo-java-specs-stored-in-bitbucket-server-938641946.html?_ga=2.251159238.1569547419.1564144916-590267622.1536673402

I am running :

mvn archetype:generate -B \
-DarchetypeGroupId=com.atlassian.bamboo \
-DarchetypeArtifactId=bamboo-specs-archetype \
-DarchetypeVersion=6.8.0 \
-DgroupId=com.atlassian.bamboo \
-DartifactId=bamboo-specs \
-Dversion=1.0.0-SNAPSHOT \
-Dpackage=tutorial \
-Dtemplate=minimal

The error I get is :
