While moving the kie-wb modules to new locations the names and GAV information will change. This causes the modules that depend on them to break. Here is a list that hopefully helps to fix them.

org.kie.guvnor:guvnor-project-api

moved to 

org.kie.workbench.services:kie-wb-common-project-api

org.kie.guvnor:guvnor-project-backend

moved to

org.kie.workbench.services:kie-wb-common-project-backend

org.kie.guvnor:guvnor-project-client

was no longer needed and it was removed.

Packages changed, for example

org.kie.guvnor.project.service

is now

org.kie.workbench.common.services.project.service
