Help with compiling bukkit plugins

Hi, I have no idea how to compile plugins so could someone be really helpful and compile one for me? Here's the link to the zip with all the components: https://drive.google.com/file/d/0B98hKzm1mj-2SkpUWE92LWM0Umc/view?usp=sharing Thankyou once again.

 

@timtower no, it is not my own code.

I'd like someone to do it as the tutorials are outdated and unclear

 

@timtower why cannot someone else do it? I'm sure it's quite simple.

 

@timtower the developer has given me permission

 

@timtower i couldn't prove it, no

@timtower ok, i opened it up in eclipse and then ran it as a maven install. I get this error

error ;_; (open) error ;_; (close)
