I'm getting the below error when trying to compile CSS files.
This is using the latest source from Github (SHA 098b99f02633892dfcb281209de581fa0ae03d11), and built the compiler locally. I'm no Java expert, so any help resolving this will be appreciated.
Exception in thread "main" java.lang.NullPointerException

Kind regards
