Add-on packaging: requirements for POM

I submitted my first cut at an add-on yesterday. I noticed that there is no POM shown in my entry. My Jar was produced by Maven, and does include a POM stating the dependencies where Maven puts it (in
META-INF\maven\org.vaadin.addons\criteriacontainer\pom.xml).

What did I miss ? Here is a link to the
offending jar
in the add-on directory.
