Generating models and CRUD with custom baseclass - FAIL

Im generating my model:

phalcon model MYMODEL --doc --mapcolumn --extends ModelBase

notice the "ModelBase" classname. Its common.

Now I generate the CRUD:

phalcon scaffold --table-name MYMODEL

and it fails, saying ModelBase is not found. In settings, I defined the "library dir" and its there. How to tell to the commandline that my file is there?
