I use Wro4j maven plugin to concat CSS/JS files and minimize it, then I've got one problem. When I use it, I received extra .js files without content (just "?" symbol inside) for all CSS files.
I use wro.properties like this:
preProcessors=cssImport postProcessors=cssMin, jsMin
I tried anothe minimize processors (eg. yui) with same effect.
How to fix this?
