The maven-javadoc-plugin plugin declaration is duplicated, @rupeshA . I think @eeverman was referring to customizing the Javadocs using the doclet feature that the JDK provides

[eeverman]

Issue #218 is not creating javadocs for the AndHow project - Javadocs for this project already work.
This issue is about having AndHow create documentation for the project you are using it in.
So for instance, if you create MyProject that uses AndHow Properties, when you run JavaDocs, AndHow should create documentation for all of the configuration properties in MyProject and include them in the javadoc for MyProject.

That would be pretty cool, right? :-)
Sorry, that task was not well defined - I wasn't expecting someone to work on it yet. Thanks for trying on this one, however.

[eeverman]

nice catch!

[eeverman]

Actually, we do not want this here. Can you pull this out and we can keep the other cleanup that you have in the pull request?

[eeverman]

I updated the description of #218

@eeverman , sounds cool indeed, will give thought to this.
