Question

我正在尝试构建一个自定义的Terraform提供程序作为链接：https://www.terraform.io/docs/extend/writing-custom-providers.html

使用go构建是好的。但是我无法使构建与bazel一起使用。

load("@io_bazel_rules_go//go:def.bzl", "go_binary", "go_library")
load("@bazel_gazelle//:def.bzl", "gazelle")

# gazelle:prefix nox
gazelle(name = "gazelle")

go_library(
    name = "go_default_library",
    srcs = [
        "main.go",
        "provider.go",
        "resource_server.go",
    ],
    importpath = "nox",
    visibility = ["//visibility:private"],
    deps = [
        "@com_github_hashicorp_terraform//helper/schema:go_default_library",
        "@com_github_hashicorp_terraform//plugin:go_default_library",
        "@com_github_hashicorp_terraform//terraform:go_default_library",
    ],
)

go_binary(
    name = "nox",
    embed = [":go_default_library"],
    visibility = ["//visibility:public"],
)

错误：

                want Resolve(string) ("google.golang.org/grpc/naming".Watcher, error)

其他错误：

从您粘贴的错误看来，软件包google.golang.org/grpc/naming的两个副本已合并到同一二进制文件中。这会导致类型错误：这些包是不同的包（即使代码相同），并且它们的导出类型不可互换。

此处最好的做法可能是排除vendor存储库中的github.com/hashicorp/terraform目录。您可以在WORKSPACE中的相应go_repository规则中向Gazelle添加参数。这样可以防止瞪羚生成规则并解决该目录中的依赖项。

go_repository(
    name = "com_github_hashicorp_terraform",
    importpath = "github.com/hashicorp/terraform",
    # ...
    build_extra_args = ["-exclude=vendor"],
)

需要一些帮助来构建带有bazel的自定义terraform提供程序
