Cannot resolve symbol 'BillOfMaterial'

When I try to compile Axelor from sources, Intelij IDE displays an error like « Cannot resolve symbol ‹ BillOfMaterial › » from import com.axelor.apps.production.db.BillOfMaterial. I checked the source code and indeed the import package com.axelor.apps.production.db is empty. I mention that I downloaded the Axelor version 6.0.7. Does an additional module need to be loaded or is it an installation error?
