include environment specific file in playframework

Is it possible to achieve this in an application.conf file?

env = ${?ENV}".auth.conf" 
include env

The 'include' statement does not accept env. As far as I know, I can only pass a string to include, like: 

include "dev.auth.conf"

Is there a way to specify a variable to the 'include' statement?

No, that is not possible.

From the HOCON spec

Value concatenation is NOT performed on the "argument" to include or url() etc. The argument must be a single quoted string. No substitutions are allowed, and the argument may not be an unquoted string or any other kind of value.

The hypothetical feature is complicated.

a = ${b}
b = 1

resolves to a = 1. In that pattern,

include ${b}.conf
b = 1

should include 1.conf.

But what if b = 1 is defined in another include? Is

include filehavingb.conf
include ${b}.conf

different than

include ${b}.conf
include filehavingb.conf

And other complications.

Anyway, this is discussed at https://github.com/typesafehub/config/issues/122

The easiest way to achieve a similar result currently is using -Dconfig.file
