Go language configuring

I need to do a work for my university and I choose to do it using the Go language. Yesterday I installed the .msi and setted the variables to:

• GOPATH = C:\Users\Gustavo\goprojects (this is the folder that I want to place all my Go projects)
• GOROOT = C:\Go\
• PATH = C:\Users\Gustavo\goprojects\bin

After this, I installed the GoClipse plugin on my Eclipse and created a new project into the goprojects folder. Then, I created another folder in the src folder, and a .go file into this folder.

Now is my problem. When I started to write some code, everytime that I try to auto complete my code, Eclipse shows me an error and I was searching on google and found that I need to install one project from GitHub called gocode.

So I want to know where do I need to install it and how can I import it to my project.

P.S.: I am using Windows 8.1, I have git installed and the link of gocode project is: https://github.com/nsf/gocode

I solved my problem doing this steps:

• Downloaded the gocode to the src folder. (The path: C:\Users\Gustavo\goprojects\src\github.com\nsf\gocode)
• In the Eclipse, do this: Window -> Preferences.
• Open Go option in the left menu then click Tools.
• In the gocode path I set C:\Users\Gustavo\goprojects\bin\gocode.exe

And thats it! It works now.
