Go + GoLand调用其他文件中的函数

Question

目录布局：

~ cd $GOPATH
~ tree src/simple 
src/simple
└── main
    ├── main.go
    └── other.go

main.go：

package main

import "fmt"

func main() {
    fmt.Println("This is in main. calling somefunc...")
    somefunc()
    fmt.Println("done. bye :)")
}

other.go：

package main

import "fmt"

func somefunc() {
    fmt.Println("This is in somefunc in other.go")
}

这适用于go build ：

~ cd $GOPATH/src/simple/main/
~ go build
~ ./main
This is in main. calling somefunc...
This is in somefunc in other.go
done. bye :)

在GoLand IDE中，如果我运行，我得到：

main/main.go:7:2: undefined: somefunc

通常，编辑器会突出显示所有语法错误。 somefunc调用在编辑器中被视为有效语法，但是当我运行它时不起作用。 我甚至可以通过cmd单击该函数来跳转到定义。

这是GoLand 2018.2.3和go version go1.11

在GoLand中，根据Go Build模板创建运行配置Run -> Edit Configurations并进行设置

Name: Build (or whatever you like)
Run kind: Directory
Directory: /Users/gopher/go/src/simple/main/
                                      ^^^^^^
Run after build: checked
Working directory: /Users/gopher/go/src/simple

相应地更改/Users/gopher/go/ part，以匹配$GOPATH实际路径

然后Run -> Build项目

This is in main. calling somefunc...
This is in somefunc in other.go
done. bye :)
