Distillery failed with message "Multiply defined module: 'Elixir.Telemetry'"

When I tried to upgrade a running Phoenix application using Distillery, the build failed with these messages:

Generated teamgenik app
==> Assembling release..

==> Generated .appup for artificery 0.2.6 -> 0.4.1

==> Release failed with multiple errors:
    Multiply defined module: 'Elixir.Telemetry'

I operate this app for several months and I have successfully upgraded it several times. This time, I want to bump the version of Phoenix from 1.4.0 to 1.4.3.

I have read this entry on Elixir Forum:

https://elixirforum.com/t/distillery-build-error-multiply-defined-module-elixir-collectable-ecto-adapters-sql-stream/19489

I have tried mix deps.clean --all and mix release.clean. Any advice or suggestion?

UPDATE

I noticed a peculiar phoenomenon. When I executed bin/my_app upgrade 0.10.7 on the RELEASE_ROOT_DIR, I got this error message (note double quotes and a comma between them):

Could not locate code path for release-my_app","0.10.6!

Though I could not detect the root cause of my problem, I managed to upgrade my app in the following way.

  1. Stop the app.
  2. Remove the release directory.
  3. Recreate the release directory.
  4. Remove _build directory from source directory.
  5. Deploy the app with mix release.

In other words, I gave up host code swapping and chose to re-deploy my app freshly.

It seems that my prolem is related to these issues:

Both have been closed already. I think my problem was due to some bugs of the older installation of Distillery and I won't encounter it in the future.
