gcloud function: Could not find local artifact: How to solve? - google-cloud-functions

Question

My cloud function code, is a maven-jar-project. It depends on other internal maven jar, so I have added that dependency to the pom.xml.
Expected: I expect that the dependent jars will be automatically included in the cloud function deployment, however I get an error "could not find artifact". Local compilation & running does not have any issue.
I don't want to copy paste those dependency sourcecode directly to my gcloud maven project. [bad ]

Answer 1

To achieve this, you need to deploy from JAR. Like that, you create a JAR with all the dependency already included in it (maven shade). No resolution at deployment time, only get your JAR and put it in Cloud Functions.
