Sarp Kaya, just follow Mbded steps. Additional step is, ensure that your additional GOPATH should be there.

For example, this is our ~/.profile GOPATH

export GOPATH=$HOME/lib/Go:$HOME/Development/Go

The first path used by go get processes etc, while your active go development directory goes to the next path.

According to our config, the RightApp exact path should be $HOME/Development/Go/src/RightApp.

Let say you are having a project with src/ sub directory and two .go files inside: hello.go and typetest.go and both defines the same package "main". One of them (hello.go) also implements func main().

To make it compile as whole you need to make sure two things are configured properly: GOPATH and Run/Debug configuration.

Open the Project Libraries/GOPATH settings:

For Gogland

File -> Settings -> Go

For Intellij IDEA

File -> Settings -> Languages & Frameworks -> Go -> Go Libraries

Makes sure the GOPATH for the project looks something like that:

GOPATH settings

Next, open Run -> Edit Configurations and make sure your configuration looks similar to this:

Run/Debug configuration

You can add second file (in your case Data.go) as Go tool arguments field in Run/Debug Configurations. I read about this here: https://github.com/go-lang-plugin-org/go-lang-idea-plugin/issues/2013 near the end of discussion. Example below (I used 2 files HelGo.go and aaa.go) worked for me:

Go Run Configuration with 2 files

Intellij objected in these 2 files were in different folders, and so both of them has to be same package (main). On the other side I couldn't make any advises on this page work at all.
