Build with Font Awesome Pro: missing duotone.js

[AndrasJanurik]

Hi,

I am coming from #83 and there is a new error so I thought it is probably a new issue. But please check out my last comment on #83 as well because the aliases.xml and the the demo files problem might interest you.

The next problem is when using the the new font awesome pro jar file I get a maven build error:

Could not execute build-frontend goal: Error occured during goal execution: 
 
   Failed to find the following files: 
       - ./font-awesome-duotone/duotone.js
   
   Locations searched were:
       - `...\frontend` in this project
       - `META-INF/frontend` in included JARs
       - `META-INF/resources/frontend` in included JARs
 
   Please, double check that those files exist. If you use a custom directory for your resource files instead of default `frontend` folder then make sure you it's correctly configured (e.g. set 'vaadin.frontend.frontend.folder' property)

Or when trying to run it from eclipse it gives the following additional stack trace for the same error:

I checked and the jar really doesn't contain the file. The contents of the META-INF\resources\frontend folder:

\---frontend
    \---font-awesome-iron-iconset
            fab.js
            fad.js
            fal.js
            far.js
            fas.js

The contents of the META-INF\resources\frontend folder of your standard jar:

\---frontend
    +---font-awesome-duotone
    |       duotone.js
    |       
    \---font-awesome-iron-iconset
            fab.js
            far.js
            fas.js

Is this a build problem? Can you please help?
