My config is:

        new LicenseWebpackPlugin({
                pattern: /.*/,
                licenseFilenames: [ // list of filenames to search for in each package
                    'LICENSE',
                    'LICENSE.md',
                    'LICENSE.txt',
                    'license',
                    'license.md',
                    'license.txt',
                    'README',
                    'README.md',
                    'README.txt',
                    'readme',
                    'readme.md',
                    'readme.txt'
                ],
                outputTemplate: 'output.template.ejs',
                outputFilename: '[name].licenses.html',
                includePackagesWithoutLicense: true,
                addBanner: true,
                bannerTemplate: '/*! 3rd party license information is available at <%- filename %> */'
            })

as result I have Unknown license on output.

Why?

[xz64]

The can-ajax package is missing a "license" field in its package.json which is why the plugin isn't producing any output for this package.

Because the plugin filters packages by a license identifier regex, it must know the type of license for a project before it can extract the license text.

The plugin supports a licenseTypeOverrides option to handle these scenarios.

Example:

licenseTypeOverrides: {                                                 
  'can-ajax': 'MIT'                                                     
}  

I need to update the README to explain this option.

I've added some documentation to v1.2.0 which clarifies this feature. Let me know if you have any questions
