CopyWebpackPlugin - ignore a folder

New versions of CopyWebpackPlugin have changed the way of ignoring files.

new CopyWebpackPlugin({
    patterns: [{
        from: defaultSourcePath,
        globOptions: {
            ignore: [
                '**/css/my.css',
                '**/js/my.js',
                '**/index.html'
            ]
        }
    }]
})

Try this:

ignore: ['img/folder/**/*']

This will not copy the entire img/folder.

Remember to clear your destination folder before running your webpack.
