Bug Description

Generated Elixir module names such as Ory.Connection clash. Elixir dependencies cannot override each other's Modules, but the generated code does contain the same module name in different dependencies:

Examples:

https://github.com/ory/sdk/blob/2324e5c13c45d43c7e7b3cdc5ebc86b86b627867/clients/client/elixir/lib/ory/connection.ex#L5

https://github.com/ory/sdk/blob/2324e5c13c45d43c7e7b3cdc5ebc86b86b627867/clients/hydra/elixir/lib/ory/connection.ex#L5

https://github.com/ory/sdk/blob/2324e5c13c45d43c7e7b3cdc5ebc86b86b627867/clients/keto/elixir/lib/ory/connection.ex#L5

https://github.com/ory/sdk/blob/2324e5c13c45d43c7e7b3cdc5ebc86b86b627867/clients/oathkeeper/elixir/lib/ory/connection.ex#L5

https://github.com/ory/sdk/blob/2324e5c13c45d43c7e7b3cdc5ebc86b86b627867/clients/client/elixir/lib/ory/connection.ex#L5
This is a follwup to this comment https://github.com/ory/sdk/issues/194#issuecomment-1318133766

Reproducing the bug

Create any library importing e.g. at least 2 packages:
Example snippet from mix.exs:

defp deps do
    [
     ...
      {:ory_client, github: "ory/sdk", sparse: "clients/client/elixir/"},
      {:ory_hydra, github: "ory/sdk", sparse: "clients/hydra/elixir/"}
     ]
  end

Relevant log output

when building/running lots of warnings such as this one is logged:

warning: redefining module Ory.Connection (current version loaded from /workspace/cantex_umbrella/_build/dev/lib/ory_client/ebin/Elixir.Ory.Connection.beam)
  lib/ory/connection.ex:5

Relevant configuration

Here is the Variable setting, to which I propose to add this line:

export ELIXIR_INVOKER_MODULE="Ory.${PROJECT^}"

https://github.com/ory/sdk/blob/2324e5c13c45d43c7e7b3cdc5ebc86b86b627867/scripts/prep.sh#L85
And here the line 3 should be changed to

invokerPackage: ${ELIXIR_INVOKER_MODULE}

https://github.com/ory/sdk/blob/2324e5c13c45d43c7e7b3cdc5ebc86b86b627867/config/client/elixir.yml#L1-L3

This results in package names such as Ory.Hydra.Connection

Version

latest stable versions

Additional Context

@aeneasr I'm putting here the questions I have for understanding & documentation, These are mostly issues to get the PR right.

• How shall a PR be formulated? I'm thinking about a multi commit PR, one commit comprising the config changes, another one with each package.?
• Does the build pipeline build all clients, all the time?
• Are the old spec vertions built too?
• How does the spec version map to package versions generally [if there's a rule/docs]?
• Is there such a thing as an [aglorithmic] sdk version ?

I'll come back with a PR on this, I've already forked the sdk. The bug is easy to solve, but perhaps a followup documentation issue would benefit from those questions.

It's a rather long post, so feel free to only discuss in context of the upcoming PR.

Start with scripts/prep.sh around line 85 and config/client/elixir.yml, then compare the generated connection modules under clients/client/elixir and clients/hydra/elixir. Regenerate at least two clients and verify that their modules have distinct names and that the Mix build no longer reports redefining-module warnings.
