The lint script in the foreman just includes files from plugins into a lint run executed from the context of the foreman. This causes troubles when a plugin adds some custom lint dependency (like eslint-plugin-jest from the example below).

[foreman|2.4.1|develop] npm run lint

> TheForemanDevDeps@1.17.0 lint /home/vagrant/foreman/foreman
> eslint -c .eslintrc webpack/ script/ $(./script/foreman_plugins_eslint.js) || exit 0

Oops! Something went wrong! :(

ESLint couldn't find the plugin "eslint-plugin-jest". This can happen for a couple different reasons:

1. If ESLint is installed globally, then make sure eslint-plugin-jest is also installed globally. A globally-installed ESLint cannot find a locally-installed plugin.

2. If ESLint is installed locally, then it's likely that the plugin isn't installed correctly. Try reinstalling by running the following:

    npm i eslint-plugin-jest@latest --save-dev
