I tried to build camel based on the latest source from svn, and it failed. Following the instructions on the website I eventually got to (note: -e is my own addition, hoping to get some more info about the problem):

(BTW, "-author" seems to be perfectly valid to pass to javadoc, javadoc -help says "Provided by Standard doclet: -d <directory> Destination directory for output files -use Create class and package usage pages -version Include @version paragraphs -author Include @author paragraphs" amongst other things, so I don't know why it should complain about it.) On the previous maven step I had some errors regarding checksums, but this seems more basic than something related to those (and in any case, no error was reported at the end of that, I just happened to see some "flash" by as the process was going through).
