Specifying multiple groups within the Gemfile fails to produce a graph.

[daveshah]

When attempting to generate a dependency graph at the end of 2.1 in the CBRA book, running cobradeps -g component_diagram . succeeded (in that no errors were shown) but the resulting graph was empty. I decided to re-run with the text option to determine if this was a problem with graphviz, but this produced the following (also, an empty dependency list):

➜  sportsball git:(master): cobradeps -t component_diagram .
APP

DEPENDENCIES

 ALL PARTS

After visiting this repo and combing through the README, I decided to modify my Gemfile to see if changing the way this dependency is specified would produce different results.

If I modify my Gemfile so that I specify the component dependency this way: gem 'app_component', path: 'components/app_component', group: :direct cobradeps succeeds in producing a graph (and the text output works as well).

This works independently of me adding Bundler.require(:direct, *Rails.groups) to my application.rb (I opted to remove this since this seemed to be the case).

If I modify my Gemfile so that I specify the component dependency this way: gem 'app_component', path: 'components/app_component', group: [:default, :direct] cobradeps silently fails (as outlined initially).

I'm currently seeing this issue on Bundler version 2.0.2 and cobradeps version 0.4.1.

Do you mind posting your original Gemfile component statement?

Is it this one? https://github.com/shageman/component-based-rails-applications-book/blob/master/c2s01/sportsball/Gemfile

Here's the Gemfile in it's entirety (with the component statement @ the very bottom):

Ah, ok... So Rails 6 adds the :default group to plugins it generates. I hadn't run into this before. I will put it on my list to take a look at this, but would be happy to accept a pull request if you see a solution.

Glad to hear! I ended up forking this earlier today to see where the problem was. I started down the path of a small refactor to get a unit test around this. (Then the kiddos woke up so I probably won't get back to this until later this evening 🤣 )

I'll post what I have a bit later on 👍

[drwl]

@daveshah I'm running into this as well. Any chance you're able to post what you've got so far?
