Can anyone provide step-by-step instructions on how to build jpcsp from source?

[Marcelo_20XX]

Whenever I try to compile with NetBeans 7.3 after selecting Build Main Project I got two folders: Build and Bin, inside build are: built-jar.properties and a "empty" and "class" folder and inside bin are jpcsp.jar and the "lib" folder but not the other files that are needed to run the emu. Even if I copy the compiled jar and lib and overwrite to the ones made by the buildbot after I run the bat it just output some error message and hangs.

So NetBeans don't work for me or I am doing something really wrong
