Laravel 5 Elixir: copy all files except some

I would like to copy all the files from a directory to the public directory except some files.

Example:

/views 
   file1.html
   file2.html
   file3.html
   file4.html
   ......
   fileN.html

I want to copy all files from the view folder to public view directory except file1.html and file2.html

I could use

elixir(function(mix) {
    mix.copy('views', 'public/views');
});

But it copy all the files. Any solution for this?
