ParadoxThemePlugin not working under Windows

[krchniam]

When developing custom theme on Windows minimal webjar assets are not included in theme resources.

referencedWebjarAssets returns all referenced assets:

[info] Set(lib/foundation/dist/css/foundation.min.css, lib/jquery/jquery.min.js, lib/foundation/dist/js/foundation.min.js, lib/foundation/dist/css/foundation-prototype.min.cs
s, lib/foundation/dist/css/foundation-float.min.css)

Accoring to show webModules / mappings all referenced resources are on classpath:

[info] * (C:\Git\nczi-paradox\theme\target\web\web-modules\main\webjars\lib\foundation\dist\css\foundation-float.min.css,lib\foundation\dist\css\foundation-float.min.css
)
[info] * (C:\Git\\nczi-paradox\theme\target\web\web-modules\main\webjars\lib\foundation\dist\css\foundation-prototype.min.css,lib\foundation\dist\css\foundation-prototype
.min.css)
[info] * (C:\Git\\nczi-paradox\theme\target\web\web-modules\main\webjars\lib\foundation\dist\css\foundation.min.css,lib\foundation\dist\css\foundation.min.css)
[info] * (C:\Git\nczi-paradox\theme\target\web\web-modules\main\webjars\lib\foundation\dist\js\foundation.min.js,lib\foundation\dist\js\foundation.min.js)
...
[info] * (C:\Git\nczi-paradox\theme\target\web\web-modules\main\webjars\lib\jquery\jquery.min.js,lib\jquery\jquery.min.js)

But when compared in ParadoxThemePlugin in WebKeys.exportedMappings with include(path) there is no match, because referencedWebjarAssets are using URL slash /, but webModules / mappings are using Windows file separator \.

Our current workaround is to override referencedWebjarAssets and normalize it to file separator slashes with help of SbtWeb.path:

Assets / referencedWebjarAssets ~= (_.map(SbtWeb.path(_)))
