Maven project created from Old (1.x) Archetype

I'm trying to learn Maven following this Getting Started Guide.

I've Apache Maven 3.0.1 on Linux. I've issued the following command to create a first project:

yes | mvn archetype:generate \
  -DarchetypeGroupId=org.apache.maven.archetypes \
  -DarchetypeArtifactId=maven-archetype-quickstart \
  -DgroupId=org.obliquid.helpers \
  -DartifactId=obliquid-helpers \
  -Dversion=0.1

However, in the output I read:

[INFO] project created from Old (1.x) Archetype in dir: ...

How can I use a current version for the Archetype? Is the guide that I'm reading outdated?

As a sub-question, I've noticed that in the pom.xml mentions junit version 3.8.1, while I'd like to use junit version 4.8.x - How to change that? I can just change the version number in the XML?

Is there a better guide or book that you can suggest?
