##### Rules for dealing with devfile/api
### update_devworkspace_api: Updates the version of devworkspace crds in go.mod
update_devworkspace_api:
	go mod edit --require github.com/devfile/api/v2@$(DEVWORKSPACE_API_VERSION)
	go mod download

### update_devworkspace_crds: Pulls the latest devworkspace CRDs to ./devworkspace-crds. Note: pulls master branch
update_devworkspace_crds:
	./update_devworkspace_crds.sh --api-version $(DEVWORKSPACE_API_VERSION)
