Module Swoosh.Adapters.SMTP is not available

[doughsay]

I'm having an odd problem:

iex(1)> {:ok, conf} = Application.fetch_env(:email, Email.Mailer)
{:ok,
 [adapter: Swoosh.Adapters.SMTP, relay: {:system, "EMAIL_HOST"},
  username: {:system, "EMAIL_USERNAME"}, password: {:system, "EMAIL_PASSWORD"}]}

iex(2)> Swoosh.Adapters.SMTP.validate_config(conf)
** (UndefinedFunctionError) function Swoosh.Adapters.SMTP.validate_config/1 is undefined (module Swoosh.Adapters.SMTP is not available)
    Swoosh.Adapters.SMTP.validate_config([adapter: Swoosh.Adapters.SMTP, relay: {:system, "EMAIL_HOST"}, username: {:system, "EMAIL_USERNAME"}, password: {:system, "EMAIL_PASSWORD"}])

But other adapters are present:

iex(3)> conf = [adapter: Swoosh.Adapters.Logger]
[adapter: Swoosh.Adapters.Logger]
iex(4)> Swoosh.Adapters.Logger.validate_config(conf)
:ok

Am I doing something really silly here?

@doughsay sorry that you are running into problem with the library!

Did you add the gen_smtp dependency as stated in the installation docs?https://github.com/swoosh/swoosh#installation

The SMTP adapter is conditionally compile only if the gen_smtp_client module is loaded, as you can see here: https://github.com/swoosh/swoosh/blob/master/lib/swoosh/adapters/smtp.ex#L1.

Hope that will solve your problem. I'll look into whether we can raise an error when people try to use the module and it's not compiled.

Thanks! Sorry about not reading the instructions... I had already installed swoosh months ago, and I'm just now switching adapters; forgot to re-check the installation instructions.

No worries at all @doughsay!

@stevedomin I use elixir 1.5.2, phoenix 1.3.0 I ran all instructions and got this error

Hi @vovkats,

#128 (comment) didn't help at all?
