将Golang1.11与模块一起使用时，Protobuf导入“找不到文件”

Question

I'm use Golang 1.11 with module support, So my project is not put in $GOPATH

I am want to compile proto file,

My files structure

---

my TaskInfo.proto

syntax = "proto3";
package chaochaogege.filecatcher.common;

option go_package = "common";

import "chaochaogege.com/filecatcher/common/ChunkInfo.proto";

message TaskInfo{
    string name = 1;
    string storePath = 2;
    uint32 workersNum = 3;
    uint32 totalSize = 4;
    repeated chaochaogege.filecatcher.common.ChunkInfo chunkInfo = 5;
}

---

ChunkInfo.proto

syntax = "proto3";
package chaochaogege.filecatcher.common;

option go_package = "common";

message ChunkInfo{
    uint32 startBytes = 1;
    uint32 endBytes = 2;
    uint32 totalBytes = 3;
    uint32 downloaded = 4;
    uint32 orderId = 5;

}

---

go.mod

module chaochaogege.com/filecatcher

require (
  github.com/golang/protobuf v1.2.0
)

When I run follow (in filecatcher/common directory)

protoc --go_out=./ TaskInfo.proto

protoc said:

chaochaogege.com/filecatcher/common/ChunkInfo.proto: File not found.TaskInfo.proto: Import "chaochaogege.com/filecatcher/common/ChunkInfo.proto" was not found or had errors.
TaskInfo.proto:13:14: "chaochaogege.filecatcher.common.ChunkInfo" is notdefined.

I have googled, But all of questions are not about go module

Did I use wrong import path or My config is not correct?

If Stackoverflow cannot anwser my question, I think it's a bug. I should go to Github issue for report..

Looks like you are mixing up paths

Your import path is

import "chaochaogege.com/filecatcher/common/ChunkInfo.proto";

If you want to run protoc from inside filecatcher/common then you would want to shorten your import to just import "ChunkInfo.proto" and run the command you are trying to run now. It will work.

But if you want to keep your import statement as it is, then you would have to navigate to the parent directory of chaochaogege.com and run the following command from there as follows:

protoc -I chaochaogege.com/filecatcher/common/ chaogege.com/filecatcher/common/ChunkInfo.proto --go_out=chaochaogege.com/filecatcher/common/
