Single file inputs for buf format

[andrewparmet]

I'm trying to format a single file using Spotless' Buf integration. Spotless is running the following:

/absolute/path/to/buf format /absolute/path/to/file.proto

The file is not in a workspace; there is no buf.work.yaml anywhere in the file hierarchy.

I'm getting the same error as in #1056:

Failure: source /absolute/path/to/file.proto was not found - is the directory containing this file defined in your buf.work.yaml?

Is there any way around this? I'm mystified that this ever worked.

We'll look into it! Thanks for the bug report.

Aha - I think I've figured out why it used to work; in a sibling directory we do have a buf.work.yaml - the one generated by buf-gradle-plugin. I can rework our task order to prevent this from breaking, but it can't be a complete solution because we won't be able to achieve build idempotency; as soon as buf-gradle-plugin runs its lint check Spotless will fail again.

It seems odd that this should cause a problem. Here's the relevant portion of my file tree:

.
├── api
│   ├── buf.yaml
│   ├── build
│   │   ├── bufbuild
│   │   │   ├── buf.work.yaml
│   │   │   ├── build-extracted--include--protos-main -> ../extracted-include-protos/main
│   │   │   └── src-main-proto -> ../../src/main/proto
│   ├── build.gradle.kts
│   └── src
│       ├── main
│       │   └── proto
│       │       └── packagename
│       │           └── file.proto

And I'm running /path/to/buf format /path/to/api/src/main/proto/packagename/file.proto

Maybe this is more indicative of how it's breaking?

Here's the hack that gets it working non-idempotently:

afterEvaluate {
    tasks.withType<WriteWorkspaceYamlTask> {
        dependsOn(tasks.withType<SpotlessTask>())
    }
    tasks.withType<CreateSymLinksToModulesTask> {
        dependsOn(tasks.withType<SpotlessTask>())
    }
}

Same issue here. I have no buf.work.yaml at all, buf.yaml and buf.gen.yaml are in the root of the project. Still when I try to format a file, I get

Failure: source /absolute/path/to/file.proto was not found - is the directory containing this file defined in your buf.work.yaml?

Running simply

buf format /path/to/file

I tried both absolute and relative paths, but same result anyway

We're working on some wholesale fixes to path targeting in a branch right now that will come out in the coming weeks - we hope this will be fixed as part of that process.
