I was setting up an Ubuntu 16.04 server for my Elixir/Phoenix application with edeliver when edeliver failed with the error message ** (Mix) The task "release" could not be found along with a exit code of 1. If I go to my build server, git pull my app and run MIX_ENV=prod mix release or just mix release after getting dependencies, I get the same error.
However, the same application works without any problem locally.
My erlang version is erts-9.0 and elixir version is 1.5.5 on both the server and my local computer. Hex version is also the same at 0.16.1.
Phoenix was installed using this command: mix archive.install https://github.com/phoenixframework/archives/raw/master/phx_new.ez.
This is my mix.exs file.
defmodule MyApp.Mixfile do
use Mix.Project
def project do
[
app: :MyApp,
version: "0.0.1",
elixir: "~> 1.4",
elixirc_paths: elixirc_paths(Mix.env),
compilers: [:phoenix, :gettext] ++ Mix.compilers,
start_permanent: Mix.env == :prod,
aliases: aliases(),
deps: deps()
]
end
# Configuration for the OTP application.

# Type `mix help compile.app` for more information.
def application do
[
mod: {MyApp.Application, []},
extra_applications: [:comeonin, :logger, :runtime_tools, :earmark, :distillery, :edeliver]
]
end
# Specifies which paths to compile per environment.
defp elixirc_paths(:test), do: ["lib", "test/support"]
defp elixirc_paths(_), do: ["lib"]
# Specifies your project dependencies.

defp deps do

]
end
# Aliases are shortcuts or tasks specific to the current project.
# For example, to create, migrate and run the seeds file at once:
#
# $ mix ecto.setup
#
# See the documentation for `Mix` for more info on aliases.
defp aliases do
[

"ecto.reset": ["ecto.drop", "ecto.setup"],
"test": ["ecto.create --quiet", "ecto.migrate", "test"]
]
end
end
My edeliver configuration file .deliver/config is as follows:
APP="MyApp"
BUILD_HOST="1.1.1.1"
BUILD_USER="ubuntu"
BUILD_AT="/home/ubuntu/app_build"
PRODUCTION_HOSTS="1.1.1.1"
PRODUCTION_USER="ubuntu"
DELIVER_TO="/home/ubuntu/app_release"
pre_erlang_get_and_update_deps() {
local _prod_secret_path="/home/ubuntu/app_config/prod.secret.exs"
if [ "$TARGET_MIX_ENV" = "prod" ]; then
__sync_remote "
ln -sfn '$_prod_secret_path' '$BUILD_AT/config/prod.secret.exs'
"
fi
}
