webpack-cli@v4.2.0 breaks color support on CI/CD

[proton-ab]

Describe the bug

Automated color detection was broken in v4.0.0 and subsequently fixed in v4.1.0. It is now broken again in v4.2.0 but only partially. The removal of --color flag also means we can not override this behavior and are left with uncolored output on CI.

Expected behavior

Either color support is properly detected or an override flag is provided again.

v4.2.0:

Please note that Drone fully supports ANSI colors but might not be properly detected by some tools (or outright blocked due to CI environment variable being detected)

Thanks for the report. I'm looking into it.

We still support --color flag. You can use it.

webpack-cli/packages/webpack-cli/lib/utils/cli-flags.js

Line 93 in 0caa918

name: 'color',

EDIT: --color is true by default so no need to pass it explicitly.

Note for myself:

// webpack.config.js
module.exports = [{
    entry: './src/index.js',
},
{
    entry: './src/index.js',
}];

adding test for multi compiler mode
