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. I don’t really know how to go about debugging/solving that issue though…
The verbose logs from the Distillery run are available here under the ‘Details’ of that post: https://github.com/bitwalker/distillery/issues/627#issuecomment-455009534
Here’s my entire mix.exs if that helps any…
