public class CssImportPreProcessor
extends AbstractCssImportPreProcessor

CssImport Processor responsible for handling css @import statement. It is implemented as both: preProcessor & postProcessor. It is necessary because preProcessor is responsible for updating model with found imported resources, while post processor removes import occurrences.

When processor finds an import which is not valid, it will check the WroConfiguration.isIgnoreMissingResources() flag. If it is set to false, the processor will fail.
