self defined variables like "MY_PACKAGE_ROOT" in the resources section wont get honoured and resolved in the project export and XDC creation stage.
instead some warnings on exactly the defined variables will pop up plus replacements with an empty expression.
this is most probably a problem of this revision since former revisions just worked with the very same project setup.
i doubt its the import filter since basically all looks fine in the GUI - only at export times the problem gets visible.
