Elixir deps can't be compiled

[jonas-jonas]

The SDK build for elixir is failing with this error message [1] when using the 7.4.0 version of the open-api-generator for elixir.

I couldn't install a newer version of elixir in the docker image for some reason, and as the version that's available to our docker base image is v1.10.3 which is pretty old, I suspect, that that might be the issue.
