Compiling BungeeCord myself

Here is my problem / question:

The title spoilers but i wanted to compile bungeecord myself so i putted the source in my workspace (ecplipse)
and then i searched all the erros that said "import xx.xx.xx" so all import errors are gone after i downloaded 22 jar files so please can i fix the errors fast or does i have to download more jar files (if anyone had a list it would be great :3)

Please do not be nasty to me im german..
