Go build multiple/nested packages?
问题
我刚刚开始学习Go（所以没有经验），想知道Go是否支持任何形式的“构建所有源文件”，就像mvn install那样。
我的项目结构是：
src
`-github.com
`-myproject
|- package1
| `- main.go
`- package2
|- lib1_used_by_main.go
`- lib2_used_by_main.go
当我执行以下命令时：
cd src/github.com/myproject
go build
会出现src/github.com/myproject中没有可构建的Go源文件的错误，这是正确的，因为所有的源文件都在子包中。
是否有一条命令可以构建所有的子包，而不需要显式地列出每个子包？
英文:
I just started writing Go today (so 0 experience), and wonder if Go supports any form of "building all source files" like what mvn install does.
My project structure is
src
`-github.com
`-myproject
|- package1
| `- main.go
`- package2
|- lib1_used_by_main.go
`- lib2_used_by_main.go
When I do
cd src/github.com/myproject
go build
this fails with no buildable Go source files in src/github.com/myproject, which is kind of right, because all source files are in subpackages.
Is there a command to build all subpackages, without listing each of them explicitly?

在你使用cd命令切换到基础目录之后，使用go build ./...命令。注意，这里有三个点，表示省略号。这将递归地构建所有子目录。当然，你也可以在任何地方使用go build path/to/my/base/...命令，而不需要切换到该目录。
对于那些依赖于go/pkg目录的集成开发环境（IDE），比如SublimeText3与GoSublime，这非常有用。如果对一个依赖包进行更改，直到你构建该包并将其放置在go/pkg目录中，自动完成功能才会更新。
我的项目被分成多个包结构，所以我经常需要运行go build ./...来更新自动完成功能。
英文:
After you cd to the base directory, use go build ./... Note that there are 3 periods as it is an ellipsis. This will recursively build all subdirectories. Of course you can always do go build path/to/my/base/... from wherever without needing to cd to the directory.
This is very useful for those who use an IDE that relies on the go/pkg directory, such as SublimeText3 with <a href="https://packagecontrol.io/packages/GoSublime">GoSublime</a>. Making changes to a dependency package won't update the autocompletes until you build the package, which places it in the go/pkg directory.
My own projects are broken into a multiple package structure, so I frequently have to go build ./... to update my autocompletion.
