There's no rubocop task in the Rakefile:

Run if [ -f Rakefile ] ; then
rake aborted!
Don't know how to build task 'rubocop' (See the list of available tasks with `rake --tasks`)

I raised it before, but should we start assuming Rubocop as an executable exists and always use that?

https://github.com/theforeman/foreman_webhooks/pull/71/files#r1450828173 is also an option.

@ofedoren looks like there are RuboCop failures. Mind taking a look?

[archanaserver]

@ekohl i'll take a look and raise a PR with the rubocop fix here

[archanaserver]

This should fix it now: #182

[ofedoren]

I've fixed rubocop here, but the tests are now red due to webpack changes. I'm not so sure how to fix it though.

@MariaAga, sorry for bothering you, I think you already work on that, but just to make sure: should we wait a bit or should we (I mean plugin maintainers) do something to fix the issues?

Could you change css files to:

 - @import '~@theforeman/vendor/scss/variables';
+ @import 'node_modules/@theforeman/vendor/scss/variables.scss';

Its failing tests without it and its not a priority to investigate right now as its only a test issue
