Using the following elixir and erlang on Ubuntu 22.04
Erlang/OTP 24 [erts-12.3.2.3] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1] [jit]
Elixir 1.13.4 (compiled with Erlang/OTP 24)
On a fresh phoenix v1.6.11 app I am getting the following warning on launching the server
warning: the :gettext compiler is no longer required in your mix.exs.
Please find the following line in your mix.exs and remove the :gettext entry:
compilers: [..., :gettext, ...] ++ Mix.compilers(),
(gettext 0.20.0) lib/mix/tasks/compile.gettext.ex:5: Mix.Tasks.Compile.Gettext.run/1
(mix 1.13.4) lib/mix/task.ex:397: anonymous fn/3 in Mix.Task.run_task/3
(mix 1.13.4) lib/mix/tasks/compile.all.ex:92: Mix.Tasks.Compile.All.run_compiler/2
(mix 1.13.4) lib/mix/tasks/compile.all.ex:72: Mix.Tasks.Compile.All.compile/4
(mix 1.13.4) lib/mix/tasks/compile.all.ex:59: Mix.Tasks.Compile.All.with_logger_app/2
(mix 1.13.4) lib/mix/tasks/compile.all.ex:36: Mix.Tasks.Compile.All.run/1
When I remove the :gettext entry from mix.exs {:gettext, "~> 0.18"},
the server doesnt launch and I get the error:
** (Mix) The task "compile.gettext" could not be found. Did you mean "compile.leex"?
I have tried this on many new phoenix apps but this behavior persists.
Update - I built a new app with the --no-gettext
flag and this resolved the warning.
