cleanAfterEveryBuildPatterns: ['*.LICENSE.txt'] doesn't seem to work

[Jun]

Issue description or question

I tried to use cleanAfterEveryBuildPatterns: ['*.LICENSE.txt'] to remove LICENSE.txt files. According to this comment, the person was able to remove the LICENSE.txt files. However, it doesn't seem to work for me.

Webpack Config

A minimal repo: https://github.com/Jun711/clean-webpack-test

// paste your webpack config here
const path = require('path');
const { CleanWebpackPlugin } = require('clean-webpack-plugin');

module.exports = {
  mode: 'production',
  entry: [
    './src/test.js',
  ],
  module: {
    rules: [
      {
        test: /\.m?js/,
        resolve: {
            fullySpecified: false
        }
      },
      {
        test: /\.(js)$/,
        exclude: /node_modules/,
        use: ['babel-loader']
      }
    ]
  },
  resolve: {
    extensions: ['*', '.js']
  },
  plugins: [
    new CleanWebpackPlugin({
      cleanAfterEveryBuildPatterns: ['*.LICENSE.txt'],
    })
  ],
  output: {
    filename: '[name].js',
    path: path.resolve(__dirname, 'dist'),
  }
}

you should add protectWebpackAssets: false

 plugins: [
    new CleanWebpackPlugin({
      protectWebpackAssets: false,
      cleanAfterEveryBuildPatterns: ['*.LICENSE.txt'],
    })
  ],
