Oops, let me explain better. My source files have always been in the right places, relative to $GOPATH. The difference is just in the IntelliJ module configuration.
When I select File->Project Structure and click on a Go module, I would expect that I can click "Add content root" and put it anywhere I want. Then browse in the directory tree (on the right hand side) to find the "src" directory, right-click and select "Sources".
Then when resolving Go symbols, IntelliJ should look for directories marked "Sources" or "Test Sources" and resolve paths from there. (This is based on how it works for Java modules.

尝试众多golang的ide，最后发现intellij目前做的完成度最高
eclipse go 不能进行包、类、方法等的跳转，这点是无法忍受的，所以果断换成intellij
但是发现在intellij里面不能import $GOPATH里src下的包，网上搜索了很长时间，
在这里找到解决方法：https://github.com/mtoader/google-go-lang-idea-plugin/issues/224
Looking through the source, it seems that the plugin doesn't use the $GOPATH (to be fair, I think earlier Go docs didn't make the distinction between using $GOPATH and $GOROOT quite as clear as they do now).
In setting up the plugin you have to
1.) create symlinks for all of the imported package directories in your $GOPATH:
a. $GOROOT/src/pkg/ -> $GOPATH/src
ex. from within $GOROOT/src/pkg, ln -s $GOPATH/src/github.com
b. $GOROOT/pkg/target/ -> $GOPATH/pkg/target/
ex. from within $GOROOT/pkg/darwin_amd64, ln -s $GOPATH/pkg/darwin_amd64/code.google.com
2.) you MUST set up a source directory when creating the project (however, it can be an empty string, which will then cause the wizard to prompt you that it will set the project root as the source directory)
