Hello,
I'm trying to figure out how to use this in a monorepo. I've got the following structure:

project
└─── go
│   └─── functions
│   │   └─── func_A
│   │   │   └─── cmd
│   │   │   │    main.go
│   │   │    code_A.go
│   │   └─── func_B
│   └─── pkg
│   │    go.mod
│   │    go.sum
└─── ui
└─── infra

each func_* folder holds multiple functions (for example one could be all the user endpoints, one all the group endpoints), but the idea is to have them run as one function per endpoint in GCP.

If I run with just go run . everything is good:

vscode ➜ .../go/function/funca/cmd $ go run .
Serving function: "Code_A"

The problem is when I try to get it to work in build pack.

When I try to build it:

vscode ➜ /workspaces/testFolder $ pack build test-build --path /workspaces/testFolder/go --builder gcr.io/buildpacks/builder:google-22 --env GOOGLE_FUNCTION_SIGNATURE_TYPE=http --env GOOGLE_FUNCTION_TARGET=Code_A --env GOOGLE_BUILDABLE=./function/funca

If I separate it in 2 modules (one module for the function folder, one for the core folder, which creates some go mod vendor fund). I can only get it to build IF the functions are declared at the root of the function module (as a package, but at the root). But I can't seem to be able to execute them.

I'm surely missing something, is anyone using a monorepo with
