Eslint-plugin-import: import/order 2.20.1

[retarsis]

This package works incorrectly on v2.20.1 for import/order rule.
Previously I was working on v2.18.x and the rules worked as I expected in accordance with the documentation.
After package upgrade I got an error:
There should be no empty line within import group import/order

This error happens where it should not.
If it'd help, v2.20.0 works fine as expected and only the latest patch version produces this behavior.

.eslintrc.json

    "import/order": [
      2,
      {
        "newlines-between": "always",
        "groups": [
          ["builtin", "external"],
          ["parent", "internal", "sibling", "index", "unknown"]
        ]
      }
    ]

component.jsx

import React from 'react';
import ReactDOM from 'react-dom';

import { App } from './App/App';
import { unregister } from './serviceWorker';
import './index.css';

Which line is warned on?

[ljharb]

I'm not sure what in v2.20.1 would have caused this; #5625 should only affect alphabetize (cc @wschurman), #1605 would only affect the external module folders setting.

What's your full eslint config?

[wschurman]

What's the full code of component.jsx? Sometimes I get this warning when theres an errant import or require below in the body of the code.

[retarsis]

@wschurman
I don't think if this is the same case;
be sure that the error is on the 2nd line

to make it clear I did several times the same thing:
1) install 2.20.0
2) run lint + check the component. Everything is fine.
3) install 2.20.1
4) run lint (caught errors) + check the component (eslint plugin displayed an error)

full code:

import React from 'react';
import ReactDOM from 'react-dom';

import { App } from './components/App';
import { unregister } from './serviceWorker';
import './index.css';

ReactDOM.render(<App />, document.getElementById('root'));

// If you want your app to work offline and load faster, you can change
// unregister() to register() below. Note this comes with some pitfalls.
// Learn more about service workers: https://bit.ly/CRA-PWA
unregister();

@maktarsis are you on windows?

Either way, can you also try with the latest commit on master for this plugin, and see if your problem is fixed?

[retarsis]

@ljharb yeah, I am

Ok, I'll probably try

[ljharb]

I'll close this for now, but am happy to reopen if the issue isn't solved on latest master.

[retarsis]

@ljharb everything is fine now
