When retrobmda required a long classpath to compile (in my case it's an Android project with AndroidAnnotations and lot's of dependencies), it generates too long command line to be acceptable for Windows (see http://pastebin.com/vzwP1bdX) and fails to launch java process ("CreateProcess error=206, The filename or extension is too long", see http://pastebin.com/6PpR0npu)
