Description

When performing a generation while passing in artifactId, groupId, or version as a system property, required property default values using velocity expressions are evaluated incorrectly.

As an example, I have an archetype with groupId com.apache and artifactId automation-archetype. If I attempt to generate using the following command:

mvn archetype:generate -DarchetypeGroupId=com.apache -DarchetypeArtifactId=automation-archetype -DartifactId=hello-world-automation

And I have a required property defined as:

<requiredProperty key="artifactPackage">
  <defaultValue>${artifactId.replace("-", "_")}</defaultValue>
</requiredProperty>

Then the resulting property is evaluated to automation_archetype instead of hello_world_automation.

This changed from version 2.2 to 2.3 by a patch introduced in ARCHETYPE-397.

Proposed additional patch is attached.
