Elixir 1.9.4 Edeliver1.7/Distillery2.1.0 upgrade build error: Multiply defined module

[robert3rdm]

I have tried the solution of deleting the build directory from the link below:

Distillery build error: Multiply defined module: 'Elixir.Collectable.Ecto.Adapters.SQL.Stream'

Trying to build a Phoenix 1.4 application via Distillery, and hitting this error: ==> Release failed with multiple errors: Multiply defined module: 'Elixir.Collectable.Ecto.Adapters.SQL.Stream' I’ll note that this application is upgraded from Phoenix 1.3.4, and I did clean all the Elixir and Node deps and rebuild them prior to this run. Google doesn’t seem to be much help with that error, my understanding is that it means the module is defined multiple times through more than 1 dependency…

And still get the following error:

I am using edeliver 1.7 and distillery 2.1.0 with an umbrella project. I have been using edeliver and distillery with elixir 1.6 successfully. The recent upgrade to 1.9 has forced the updates of distillery and edeliver. I appreciate any feedback.

I also am experiencing this issue and have not found a solution. I’ve been stuck debugging this issue for days so it would be great if anyone knows a solution!
