Ok, I'll address some points in order. My current command line is this:
----------------------
mvn -e archetype:generate -DgroupId=com.att.idp -DartifactId=MyApplication
-Dpackage=com.att.idp -DarchetypeGroupId=com.att.idse
-DarchetypeArtifactId=idse-springmvc-archetype
-DarchetypeVersion=2.0.0-SNAPSHOT
--------------------------
And this is a relevant excerpt of the pom.xml from the archetype:
--------------
<groupId>com.att.idse</groupId>
<artifactId>idse-springmvc-archetype</artifactId>
<version>2.0.0-SNAPSHOT</version>
<name>IDP Jersey Archetype</name>
<description>Maven Archetype for creating the IDP microservices
project</description>
<packaging>jar</packaging>
----------------------------------------
Note that it uses the "jar" packaging, but I'll come back to that later in
this message.
Running this results in the following:
--------------------------

-----------------------------
Next, if we attempt to change the "packaging" to "maven-archetype" as you
state, and as shown in the examples, I get this when I try to "mvn install"
that:
----------
Unknown packaging: maven-archetype @ line 14, column 13
----------
I am using Maven v3.8.2. I tried testing with v3.9.2, and it gets the same
error.
