"go build ./..." cannot find package

I know internet full of similar issues and I tried all of suggested solutions, but can't figure out it at least 2 days.

I trying to deploy little Go server I using IntelliJ IDEA and it works great, it can build/run my code, but if I use terminal as example:

go build ./...

I see something like that:

OS-X-Dennis:backend denis$ go build ./...
out/production/mypocket_backend/server.go:4:2: cannot find package "api.jwt.auth/routers" in any of:
        /usr/local/go/src/api.jwt.auth/routers (from $GOROOT)
        /Users/denis/Programming/Golang/src/api.jwt.auth/routers (from $GOPATH)

OS X 10.11.2, IntelliJ IDEA 2016.1<br>
$GOPATH = "Users/denis/Programming/Golang"<br>
$GOROOT = "/usr/local/go"<br>
$PATH = "$PATH:$GOPATH/bin"<br>
These paths are correct? <br>

Here is my work structure:

/Golang/
 .bin/
 .pkg/
    .darwin-amd64/
         .//other folders/
 .src/
     .github.com/
     .backend/ //project's source
           /src
              /api.jwt.auth/
                //source code
           .server.go - file with main func
          //other files as example .gitignore
     .//other folders// 

Here is my screen of main file and whole project-structure:

I see that logs show me wrong path to my project.

 now
 /Users/denis/Programming/Golang/src/api.jwt.auth/routers
should
 /Users/denis/Programming/Golang/src/backend/src/api.jwt.auth/routers

I don't know where I should correct this path.

Your GOPATH can have multiple directories in it.

If you truly want your backend directory to be a path of some of your Go libraries, in addition to your existing path of /Users/denis/Programming/Golang you can set your GOPATH to: /Users/denis/Programming/Golang:/Users/denis/Programming/Golang/src/backend

This will cause import statements to search for source files in both the /Users/denis/Programming/Golang/src directory and the /Users/denis/Programming/Golang/src/backend/src directory.

I would personally recommend moving your api.jwt.auth folder to /Users/denis/Programming/Golang/src/api.jwt.auth to keep your source all in one area, but having two different directories in your GOPATH as suggested above will work too.

To understand GOPATH better, you can simply type go help gopath. Also a quickstart is here
