feat: compatible with eslint-webpack-plugin

[fangbinwei]

1. compatible with eslint-webpack-plugin. it seems the plugin groups eslint-loader's errors as Module Error before. So now grouping eslint-webpack-plugin's error as transformers/esLintError.js at least.

eslint-loader will emit multi-errors according to the number of files with errors. eslint-webpack-plugin will gather and throw only one compilation.errors/warnings. It is caused by the difference between loader and plugin in some degree.

2. change 1 errors to 1 error

Is there any update on this PR? It would be nice to have support for eslint-webpack-plugin.

I've shipped this feature in my fork of this plugin: https://github.com/sodatea/friendly-errors-webpack-plugin/releases/tag/v1.8.0

That's great! There are also a few features and necessary bugfixes in the next/2.0.0-beta.2 version that have been sitting in a beta release for a little over a year you might not want to miss.

I noticed there seem to be [some]* cases where certain rules emit an error that isn't parsed properly. Not exclusive to this branch- but another incompatibility between friendly-errors and the new eslint plugin.

*I think there are several but at least no-unused-vars

I have no idea, could you provide reproduction repo? @binury
