Can not use !negative pattern to exclude directories in multiple webpack configs

[popolan1986]

Issue description or question

I fail to use !negative pattern to exclude directories in multiple webpack configs to prevent this plugin from deleting nested paths. After building, the nested directory abc is deleted.

Webpack Config

const {CleanWebpackPlugin} = require('clean-webpack-plugin');

module.exports = [
  {
    entry: 'src/index.js',
    output: {
        path: path.resolve(__dirname, 'dist')
    }
    plugins: [
       new CleanWebpackPlugin({
          cleanOnceBeforeBuildPatterns: ['**/*', '!abc/**/*'],
       })
    ]
  },
  {
    entry: 'src/abc/abc.js',
    output: {
        path: path.resolve(__dirname, 'dist', 'abc')
    }
    plugins: [
       new CleanWebpackPlugin({
         cleanOnceBeforeBuildPatterns: ['**/*', '!def/**/*'],
       })
    ]
  },
  {
    entry: 'src/def/def.js',
    output: {
        path: path.resolve(__dirname, 'dist', 'abc', 'def')
    }
    plugins: [
       new CleanWebpackPlugin()
    ]
  }
];

@popolan1986 I ran into the same problem and replaced the '!excluded_dir/**/*' pattern with '!excluded_dir/**'. That does seem to work.

[popolan1986]

@sirockin , I know why the nested directory is deleted. abc/**/* matches abc's nested directories but not itself so the clean plugin deletes abc. I can use Braced section to exclude abc directory like this !abc{, **/*} (= !abc or !abc/**/*).
