I am getting attached build errors when trying to override europe1pricefactory in hybris 5.7?

I created attached class:[link text][1] In local.properties: default.pricefactory=mynacore

In extensioninfo class:[link text][2]

Please help on this urgently. [1]: /storage/temp/6584-coremanager-class.txt [2]: /storage/temp/6585-build-errors.txt
