cannot load such file -- guard/compat/plugin (LoadError)

[cornuwel]

Hi,

Guard works fine with rspec. bundle exec cucumber also works fine.
But if I launch guard with a cucumber configuration, I get the following error:

cannot load such file -- guard/compat/plugin (LoadError)

guard (2.15.0)
guard-compat (1.2.1)
guard-cucumber (1.5.4)
guard-rspec (4.7.3)
cucumber-rails (1.8.0)
rspec-rails (3.9.0)
cucumber (3.1.2)
rspec (3.9.0)

At first, I thought it came from my configuration, but even deleting the GuardFile and letting guard init cucumber generate a new one didn't fix the issue.

The error raises from this require:

guard-cucumber/lib/guard/cucumber/runner.rb

Line 1 in 03949aa

require "guard/compat/plugin"

I think the problem is that since 4c7d0e4#diff-d50e953cbce7c1199925fc21000b3fb9 guard-cucumber adds guard-compat as a development dependency instead of a regular dependency as the guard-compat documentation suggests: https://github.com/guard/guard-compat/blob/0e32e9bff1c896ff2c210d5f2658c55e673f3f49/README.md#usage-in-a-guard-plugin. (cc @todd-a-jacobs)

A simple workaround is adding guard-compat to your Gemfile, @cornuwel.

Thank you very much. I can confirm the workaround works.
For future reference, here it is:

group :development do
  gem 'guard-compat'
  gem 'guard-rspec', require: false
  gem 'guard-cucumber'
  ...
end

Thanks for pinging me with this, @paolobrasolin. I also appreciate you narrowing down part of the problem.

I think the problem is that...guard-cucumber adds guard-compat as a development dependency instead of a regular dependency as the guard-compat documentation suggests[.]

This may be part of the problem, but it shouldn't be, since guard-compat says:

Currently, [guard-compat] provides only a test helper for testing custom Guard plugins.

I wouldn't expect a test helper to be required as a runtime dependency, but guard-cucumber might be making use of it somewhere I haven't looked yet. That said, I've hopefully patched the issue for Cucumber versions below 4.x.

Pull request #40 should close this issue when merged.
