Which maven packaging value to use for a pure documentation project?

Question

I've got a multimodule Maven project, one of which is a documentation project, where I'm producing reference guides for using the other modules. I'm trying to stick to The Maven Way by using Maven's site plugin along with asciidoctor-maven-plugin.

Question is, which value should I use for the <packaging> element in my pom? It's not really a jar or any of the other built-in types. Googling for that answer leads me nowhere & everywhere... :(

Note that maven builds the site ok without specifying <packaging> (taking default of jar), but I get the warning

...
[INFO] --- maven-jar-plugin:2.3.2:jar (default-jar) @ foundation-docs ---
[WARNING] JAR will be empty - no content was marked for inclusion!
...

I'd like to not get this warning.

I usually use the packaging pom for the documentation projects. This packaging type will not create any JAR. See more information about the lifecycle binding for pom.
