Fix Go SDK Version for go-lang-idea-plugin

Problem

Go works fine from the command window, but within IntelliJ you get a message about incorrect SDK version.

Assumption

You installed Go using homebrew.

Go Environment

Here, we see that Go 1.3.1 is the current installed version:

$ go env
GOARCH="amd64"
GOBIN=""
GOCHAR="6"
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="darwin"
GOOS="darwin"
GOPATH="/Users/lex/dev/go/samples"
GORACE=""
GOROOT="/usr/local/Cellar/go/1.3.1/libexec"
GOTOOLDIR="/usr/local/Cellar/go/1.3.1/libexec/pkg/tool/darwin_amd64"
CC="clang"
GOGCCFLAGS="-fPIC -m64 -pthread -fno-caret-diagnostics -Qunused-arguments -fmessage-length=0 -fno-common"
CXX="clang++"
CGO_ENABLED="1"


Fix IntelliJ Problem

The go-lang-idea-plugin reported that it expected Go version 1.3, but got 1.3.1. So, just remove 1.3 (assuming that you don't need it) and create a symlink fro 1.3 to 1.3.1:

$ cd /usr/local/Cellar/go
  /usr/local/Cellar/go $ tdml
.
├── 1.2.2 -> /usr/local/Cellar/go/1.3/
├── 1.3
│   ├── bin
│   ├── etc
│   ├── libexec
│   └── share
└── 1.3.1
    ├── bin
    ├── etc
    ├── libexec
    └── share

11 directories
  /usr/local/Cellar/go $ rm -rf 1.3
  /usr/local/Cellar/go $ ln -s /usr/local/Cellar/go/1.
1.2.2  1.3.1/
  /usr/local/Cellar/go $ ln -s /usr/local/Cellar/go/1.3.1 /usr/local/Cellar/go/1.3


Discussion

This feels like such a hack, but I could not find a way to configure the version of the Go SDK for the go-lang-idea-plugin.

If anybody finds a better solution, please let us know. Thanks!

The Rest of the Story

I eventually found where to conigure the Go SDK in IntelliJ.

File > Folder Structure > Project Settings > Modules > Dependencies

Click the Module SDK dropdown and select the latest Go SDK (In my case it is currently Go SDK go1.3.3 darwin/adm64)

If that is not an option, you may need to click the New... button and select the path that is $GOPATH.

Also, verify that you selected the correct Go SDK in File > Project Structure > Project Settings > Project
