Trying to build my extensions more automatically and without magnetos GUI. I've wrote a little script it pulls a vanilla magento source base and my extension, puts everything together but the resulting .tgz file only contains the package.xml.

At first I got this error:

Notice: Trying to get property of non-object in /home/rof/build/downloader/lib/Mage/Connect/Validator.php on line 472

Done building package

I've look into that file and it reads like it's trying to access an object called config so I replaced that line with an hardcoded path. That's how i fixed the notice. But still nothing shows up in my .tgz file and when i execute ./mage package ... it says my files already exists. If i delete them it works but still nothing else than package.xml in my .tgz file.
