I have a Google cloud function (v2) that depends on and uses a private JAR called "base.jar". Base.jar contains a bunch of db classes for our app and is shared among several modules, including this cloud function, called "share.jar".
I'm following the instructions here for building and dpeloying a FAT jar.
https://cloud.google.com/functions/docs/concepts/java-deploy
After executing the mvn clean package and gcloud functions deploy ..., this error occurs:
ERROR: (gcloud.functions.deploy) OperationError: code=3, message=Build failed with status: FAILURE and message: [ERROR] Failed to execute goal on project Share: Could not resolve dependencies for project com.app.share:Share:jar:0.1-SNAPSHOT: The following artifacts could not be resolved: com.app:Base:jar:1.0-SNAPSHOT (absent): Could not find artifact com.app:Base:jar:1.0-SNAPSHOT -> [Help 1]

Here is the pom.

Note that this "share" project is a module of a parent pom, which includes a module for "Base" as well as "Share".
Parent
- Base
- Share
In any case, after clean/install I can see the target directory has a JAR without the included classes from Base. However, the deployment directory has a JAR that includes the classes from Base. So, I delete the first JAR and run google cloud deploy and still the error occurs.
UPDATE 1: Per Janez's comment, here is the pom with the parent proejct referenced. Similar problem occurs.

And here is the output of "gcloud deploy function..."
ERROR: (gcloud.functions.deploy) OperationError: code=3, message=Build failed with status: FAILURE and message: [ERROR] [ERROR] Some problems were encountered while processing the POMs: [FATAL] Non-resolvable parent POM for com.app.share:Share:0.1-SNAPSHOT: The following artifacts could not be resolved: com.app:Parent:pom:1.0-SNAPSHOT (absent): Could not find artifact com.app:Parent:pom:1.0-SNAPSHOT and 'parent.relativePath' points at wrong local POM @ line 7, column 13
THERE IS NO parent-1.0-SNAPSHOT.jar. Parent is the top level project pom!!!
It seems that the problem was resolved by updating the gcloud CLI. I was on v458. Updating to the current verion v463, seems to have resolved the problem. I'll post here further if I notice problems.
