Have you downloaded the latest SDK from the Subversion repository like the previous post to yours siuggests? If so, they haven't still updated the stand-alone project's code. Be patient, that post says that they are in the task of mantaining the SDK and all projects (including the stand-alone project) up to date. Seems that it was a bit out of date.

Keep me informed please cause I'm also trying to get inside Pentaho's SDK.

Regards.
