Problem with an AdminFaces component library

I'm using Maven to manage the dependencies of my project, but when I actually started creating XHTML pages, my project does not seem to have imported the dependencies needed to use the AdminFaces tags.

<ui:composition xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html"
        xmlns:f="http://java.sun.com/jsf/core" xmlns:ui="http://java.sun.com/jsf/facelets"
        xmlns:p="http://primefaces.org/ui" xmlns:adm="http://github.com/adminfaces"
        template="../../WEB-INF/templates/template.xhtml">

  <ui:define name="title">
      Cadastro Default
  </ui:define>

  <ui:define name="body">
      <f:metadata>
      </f:metadata>

      <adm:breadcrumb title="Cadastro Default" link="cadastro-default.xhtml?id="/>

The error happens with the tag <adm> and only with it. The other tags work normally, however the <adm> I can not use, lacking components in the library. But I've already run that same project in Eclipse and it worked, now that I've gone to NetBeans that started with those issues.
