引入Google API依赖的Proto文件Bazel编译报错求助

自定义Proto中的导入语句 #

import "google/api/annotations.proto";
import "google/api/client.proto";
import "google/api/field_behavior.proto";
import "google/api/resource.proto";
import "google/protobuf/duration.proto";
import "google/protobuf/timestamp.proto";
import "google/protobuf/field_mask.proto";

当前Bazel构建文件内容 #

load("@rules_proto//proto:defs.bzl", "proto_library")

proto_library(
    name = "monitoring_api_proto",
    srcs = glob(["v1/*.proto"]),
    visibility = ["//visibility:public"],
    deps = [
        "@com_google_protobuf//:any_proto",
        "@com_google_protobuf//:duration_proto",
        "@com_google_protobuf//:empty_proto",
        "@com_google_protobuf//:field_mask_proto",
        "@com_google_protobuf//:timestamp_proto",
        "@go_googleapis//google/api:annotations_proto",
        "@go_googleapis//google/api:client_proto",
        "@go_googleapis//google/api:field_behavior_proto",
        "@go_googleapis//google/api:resource_proto",
    ],
)

已尝试的操作 #

• 直接导入.proto文件，出现Google API相关proto对Bazel目标不可见的报错
• 仅添加@go_googleapis//google/api:annotations_proto到依赖中时无导入错误，但因缺少其他依赖导致编译失败

问题原因与解决方案 #

问题原因 #

报错提示的目标不存在，是因为@go_googleapis//google/api包内的client.proto、field_behavior.proto、resource.proto对应的proto_library目标名称不带_proto后缀，只有annotations.proto对应的目标是annotations_proto。

修改后的Bazel构建文件 #

将依赖中的错误目标名修正：

load("@rules_proto//proto:defs.bzl", "proto_library")

proto_library(
    name = "monitoring_api_proto",
    srcs = glob(["v1/*.proto"]),
    visibility = ["//visibility:public"],
    deps = [
        "@com_google_protobuf//:any_proto",
        "@com_google_protobuf//:duration_proto",
        "@com_google_protobuf//:empty_proto",
        "@com_google_protobuf//:field_mask_proto",
        "@com_google_protobuf//:timestamp_proto",
        "@go_googleapis//google/api:annotations_proto",
        "@go_googleapis//google/api:client",
        "@go_googleapis//google/api:field_behavior",
        "@go_googleapis//google/api:resource",
    ],
)

验证逻辑 #

可以查看@go_googleapis//google/api/BUILD.bazel文件确认目标名称，例如：

• client.proto对应的proto_library名称为client
• field_behavior.proto对应的proto_library名称为field_behavior
• resource.proto对应的proto_library名称为resource
