Eugene, Paul and Emmanuel, Thanks a lot for pointing me the way!
Emmanuel, I'm trying to execute the steps you told me to, but when connecting to Alioth (at git.debian.org) I get the "publickey" error. My public key is already there on Alioth and I've waited more than one hour for the cron to work. I read somewhere that I have to be in at least one project. I already asked to join pkg-java, but didn't receive any confirmation yet. Could this be the reason?
