Different Site Generation. Continuum builds wrong menu-structure.

My problem is the site-generation within continuum. If I invoke the follwong command: 'mvn site:site' over the command-line I'll get a different result than continuum builds. Continuum doesn't create the site-menu which is defined in my src/site/site.xml but over the command-line there aren't any troubles. I attached the Continuum build-output after I invoked the mvn site:site command. Thank you for your help.
