Fix load error when using Spring w/ custom config

[thewatts]

I'm currently working a project that is a Rails engine

When I add dotenv-rails to my Gemfile, and try to run a command, say: bundle exec rspec spec, this error occurs:

{gem-path}/spring-1.6.4/lib/spring/configuration.rb:31:in `application_root_path':
Spring was unable to find your config/application.rb file.
Your project root was detected at {project-root}, so spring looked
for {project-root}/config/application.rb but it doesn't exist.

You can configure the root of your application by
setting Spring.application_root in config/spring.rb. (Spring::MissingApplication)
  from {gem-path}/spring-1.6.4/lib/spring/watcher.rb:24:in `watcher`

The error is saying that Spring can't find my application_root. This is odd, because Spring allows for custom configuration, such as specifying where to find the root directory of your Rails application.

This is especially helpful when working with a Rails Engine, and the root of the application lives within the dummy app.

In my project, Spring's application_root is configured via a ./config.spring.rb file.

In lib/dotenv/rails Spring's watcher file was being included, but that watcher file doesn't trigger the loading of custom Spring configurations.

Those includes take place in Spring's commands file.

Specifically:

• Loading of .spring.rb files
• Loading of ./config.spring.rb files

Changed lib/dotenv/rails to instead include spring/commands (which in itself includes the watcher file). This allows for Spring to preload any configurations before dotenv-rails uses the Spring.watch
command.

Hey @bkeepers - would you be willing to push a new version of this gem now that this has been merged?

[bkeepers]

Yup, 2.1.1 is now released!
