Please use svnpubsub for publishing website and artifacts. Infra team doesn't recommend the use of maven site:deploy and direct scp copy to www.apache.org/dist directory. If you have any question about it, you should contact to infra team. I don't know why they decided like that ...
So, simply, you can follow the following steps: http://wiki.apache.org/hama/HowToRelease
and, To publish the website,
$ mvn site // build site
$ svn co https://svn.apache.org/repos/asf/incubator/mrql/site ~/mrql-site
$ cd ~/mrql-site; svn commit ./ -m "comment here"
If you have no commit access, please let me know.
