Issue with v2 of buf.build

[dytavan]

I've tried a buf generate with your example and I've adapted both buf files as I do with GO successfully:

buf.yaml:

version: v2

modules:
- path: proto

and buf.gen.yaml:

version: v2

plugins:

- remote: buf.build/community/neoeinstein-prost:v0.4.0
  out: src/gen
  opt:
  - compile_well_known_types
  - extern_path=.google.protobuf=::pbjson_types
  - file_descriptor_set
  - enable_type_names

- remote: buf.build/community/neoeinstein-prost-serde:v0.3.1
  out: src/gen

- remote: buf.build/community/neoeinstein-tonic:v0.4.1
  out: src/gen
  opt:
  - compile_well_known_types
  - extern_path=.google.protobuf=::pbjson_types

- remote: buf.build/community/neoeinstein-prost-crate:v0.4.1
  out: .
  strategy: all
  opt:
  - include_file=src/gen/mod.rs
  - gen_crate

But when I run buf generate with strategy I have an error :

"Failure: decode buf.gen.yaml: cannot specify strategy for remote plugin buf.build/community/neoeinstein-prost-crate:v0.4.1"

And if I delete strategy :

"Failure: failed_precondition: plugin "buf.build/community/neoeinstein-prost-crate:v0.4.1" failed: No such file or directory (os error 2)"

I've uploaded the files here if needed https://github.com/davidyannick86/build-with-buf

Can you help me please ?

thanks

@davidyannick86 any updates on this? I have the same exact problem :(

nope no update :(

Actually, for post-crates, I use protoc in local instead of buf build and can successfully build @davidyannick86.

Feature flag generation in protoc-gen-prost-crate relies on accessing files that aren't available to remote plugins. The remote plugin will only work with the no_features option.

To continue to generate the feature flags you can install protoc-gen-prost-crate and use it as a local plugin.

cargo install protoc-gen-prost-crate

version: v2
plugins:
- remote: buf.build/community/neoeinstein-prost:v0.4.0
  out: src/gen
  opt:
  - compile_well_known_types
  - extern_path=.google.protobuf=::pbjson_types
  - file_descriptor_set
  - enable_type_names
- remote: buf.build/community/neoeinstein-prost-serde:v0.3.1
  out: src/gen
- remote: buf.build/community/neoeinstein-tonic:v0.4.1
  out: src/gen
  opt:
  - compile_well_known_types
  - extern_path=.google.protobuf=::pbjson_types
- local: protoc-gen-prost-crate
  out: .
  strategy: all
  opt:
  - include_file=src/gen/mod.rs
  - gen_crate

Hey hey. I'm trying to get through the backlog of PRs to catch up all the dependencies, then I will take a look at this.

[saeidakbari]

hey @siennathesane any update on this? still getting the same error.

hey all, this is covered in the README:

https://github.com/neoeinstein/protoc-gen-prost?tab=readme-ov-file#example-bufgenyaml

Specifically:

When executing protoc-gen-prost-crate with the gen_crate option, remote generation is not possible, as the manifest template is not made available to a remote plugin.

You can use protoc-gen-prost-crate as a local plugin (or of course, take a look at Buf's generated Cargo SDKs to handle packaging 😄).
