Setup specific GOPATH for your own Project

Create GOPATH folder
Create a folder in your project directory.This folder is going to be your GOPATH folder.
I creeated a folder named go for my specific GOPATH inside my project.

cd go
mkdir src

Create project folder

cd src
mkdir msync # project folder

Setup Jetbrains Gogland IDE

set the IDE to use your specific GOPATH not the global GOPATH

go get

every time you want to get an external package open a terminal ( I have tested in Linux) :

go env # for checking env
go get
