did you do what the error messages above suggest?

Yes I run:

mix deps.get
Running dependency resolution...

I meant this part.

What does it mean? Here are my deps:

  defp deps do
    [{:phoenix, "~> 1.2.1"},
     {:phoenix_pubsub, "~> 1.0"},
     {:phoenix_html, "~> 2.9"},
     {:phoenix_live_reload, "~> 1.0", only: :dev},
     {:gettext, "~> 0.11"},
     {:poison, "~> 3.0", override: true},
     {:cowboy, "~> 1.0"},
     {:bypass, "~> 0.6.0", only: :test},
     {:sap_odata_service, in_umbrella: true}
     ]
  end

Check out a mix.exs file in your “soap_odata_service” umbrella app. It is here:

/home/anujit/elixir/weight_protocol/apps/sap_odata_service/mix.exs

there is an entry for bypass that points to git repo, while one of dependencies points to a version of package from hex.pm.

You need to decide which one to use, and add “override: true” to the line.

It works Thanks so much.
What does override: true mean?

Google “elixir hex mix override true” as an exercise in Google-Fu and let me know if it still needs clarifications. If so, I’ll explain.

I read the doc

It is not clear for me.
Thanks

When you specify “override: true”, the resolution dependency done by mix will force the use of version that you specify in mix.exs file. It will ignore versions required by other dependencies in case the conflict is detected.

This obviously mean you should use this with caution. Using override: true it is perfectly possible to force a dependency that is incompatible with one of the other libraries. The result may be that your project won’t compile anymore, or - worse - that it will but something will malfunction because you forced incompatible library version.

Awesome thanks so much.
