英文:
Import .proto files from another project
问题
我想将一个在不同项目中定义的.proto文件导入到我的golang项目中，并在其中使用定义的消息类型。
我想要导入的.proto文件是：https://github.com/lyft/clutch/blob/main/api/k8s/v1/k8s.proto
我已经添加了导入语句：
import "github.com/lyft/clutch/api/k8s/v1/k8s.proto";
为了使用该文件中的消息类型"Job"，我添加了以下内容：
message Jobs {repeated clutch.k8s.v1.Job job = 1;}
当我尝试编译.proto文件时，我遇到了以下错误：
导入"github.com/lyft/clutch/blob/main/api/k8s/v1/k8s.proto"未找到或存在错误。"clutch.k8s.v1.Job"未定义。
英文:
I want to import .proto file defined in different project into my golang project and use a message type defined in it.
Proto file I want to import is: https://github.com/lyft/clutch/blob/main/api/k8s/v1/k8s.proto
I have added the import statement as :
import "github.com/lyft/clutch/api/k8s/v1/k8s.proto";
to use message type "Job" in that file, I added
message Jobs {repeated clutch.k8s.v1.Job job = 1;}
When I try to compile proto file, I'm getting the error
Import "github.com/lyft/clutch/blob/main/api/k8s/v1/k8s.proto" was not found or had errors."clutch.k8s.v1.Job" is not defined.

为了编译您的proto文件，您需要克隆依赖的仓库，并将其设置为protoc导入的包含路径，例如：
<kbd>job.proto</kbd>
syntax = "proto3";package clutch.k8s.v1;// 定义option go_package = "github.com/job";import "api/k8s/v1/k8s.proto";message Jobs {repeated clutch.k8s.v1.Job job = 1;}
<kbd>compile.sh</kbd>
proto_out_dir=.GOBIN=~/go/binprotoc \--go_out "${proto_out_dir}" \--go_opt paths=source_relative \--go-grpc_out "${proto_out_dir}" \--go-grpc_opt require_unimplemented_servers=false,paths=source_relative \--plugin protoc-gen-go="${GOBIN}/protoc-gen-go" \--plugin protoc-gen-go-grpc="${GOBIN}/protoc-gen-go-grpc" \--go-grpc_opt=paths=source_relative \--proto_path=../protoc-gen-validate \--proto_path=../api-common-protos \--proto_path=../clutch \--proto_path=../clutch/api \--proto_path=. \job.proto
将生成：
<kbd>job.pb.go</kbd>
...type Jobs struct {state protoimpl.MessageStatesizeCache protoimpl.SizeCacheunknownFields protoimpl.UnknownFieldsJob []*v1.Job `protobuf:"bytes,1,rep,name=job,proto3" json:"job,omitempty"`}...
还可以在源代码仓库中查看如何构建proto文件这里
英文:
In order to compile your proto, you should clone the dependency repos and set as include path in the protoc import, as example:
<kbd>job.proto</kbd>
syntax = "proto3";package clutch.k8s.v1;// degineoption go_package = "github.com/job";import "api/k8s/v1/k8s.proto";message Jobs {repeated clutch.k8s.v1.Job job = 1;}
<kbd>compile.sh</kbd>
proto_out_dir=.GOBIN=~/go/binprotoc \--go_out "${proto_out_dir}" \--go_opt paths=source_relative \--go-grpc_out "${proto_out_dir}" \--go-grpc_opt require_unimplemented_servers=false,paths=source_relative \--plugin protoc-gen-go="${GOBIN}/protoc-gen-go" \--plugin protoc-gen-go-grpc="${GOBIN}/protoc-gen-go-grpc" \--go-grpc_opt=paths=source_relative \--proto_path=../protoc-gen-validate \--proto_path=../api-common-protos \--proto_path=../clutch \--proto_path=../clutch/api \--proto_path=. \job.proto
Will produce:
<kbd>job.pb.go</kbd>
...type Jobs struct {state protoimpl.MessageStatesizeCache protoimpl.SizeCacheunknownFields protoimpl.UnknownFieldsJob []*v1.Job `protobuf:"bytes,1,rep,name=job,proto3" json:"job,omitempty"`}...
