go - Bazel ** BUILD **文件中的 `importmap`和 `importpath`有什么区别

Question

这两个声明在Golang项目 Bazel BUILD 文件中具有什么不同功能。

示例场景:

go_library(
    name = "go_default_library",
    srcs = [
        "etcd.go",
        "strategy.go",
    ],
    importmap = "path_to_package",
    importpath = "path_to_package",
    deps = [
        "//path_to_dependacy:go_default_library",
        "//path_to_dependacy:go_default_library",
        "//path_to_dependacy:go_default_library",
],
)

Answer 1

importpathtype: stringdefault: required value

The source import path of this library. Other libraries can import this library using this path. This must either be specified in go_library or inherited from one of the libraries in embed.

importmap type: string default: ""

The actual import path of this library. This is mostly only visible to the compiler and linker, but it may also be seen in stack traces. This may be set to prevent a binary from linking multiple packages with the same import path e.g., from different vendor directories.
