Error while running buf generate command

[bharath-reddy-tm]

I have buf installed(version: 1.30.0) locally and trying to run buf generate command. But it is failing with following error:
Failure: files with different commits for the same module buf.build/grpc-ecosystem/grpc-gateway: protoc-gen-openapiv2/options/openapiv2.proto:18e8bf1967c947f5bd991710f490df5f and proto/mygateway-gateway/*******.proto

Even with --verbose flag I can see only one line in terminal. Please help me.

Can you share some details? Specifically:

• Your buf.yaml
• Your buf.work.yaml, if you are using one

[bharath-reddy-tm]

@timostamm Following is the .yaml file

version: v1beta1
plugins:

• name: go
  out: .
  opt:
  • paths=source_relative
• name: go-grpc
  out: .
  opt:
  • paths=source_relative
• name: grpc-gateway
  out: .
  opt:
  • paths=source_relative
  • generate_unbound_methods=true
• name: openapiv2
  out: .
  opt:
  • allow_repeated_fields_in_body=true

I don't think we are using any .work.yaml file

This looks like a buf.gen.yaml file. Unfortunately, this doesn't give me any information about what modules and dependencies you use.

Do you really not have a buf.yaml file anywhere? What command exactly are you running?

[bharath-reddy-tm]

@timostamm I cannot find any buf.yaml file in repo. I am running buf generate --template *.buf.gen.yaml --path *.proto

[timostamm]

The error messages includes "module buf.build/grpc-ecosystem/grpc-gateway", so you must be using module dependencies somehow, which requires a buf.yaml file.

Your are using a v1beta1 buf.gen.yaml, which has been outdated for quite some time (see the migration guide), and your project seems to be in a broken state. I recommend to set up a small project from scratch to get familiar with the concepts. The grpc-gateway has excellent step-by-step guides to get you started with buf right in their README. If you follow the guide, it should be quite simple to get the basic annotations running, and you can add openapi annotations in a separate step. This will give you a working example to compare against.

Thank you @timostamm
