Directory prefix src does not contain main module or its selected dependencies

[stephanwesten]

Welcome

• Yes, I'm using a binary release within 2 latest major releases. Only such installations are supported.
• Yes, I've searched similar issues on GitHub and didn't find any.
• Yes, I've read the typecheck section of the FAQ (https://golangci-lint.run/usage/faq/#why-do-you-have-typecheck-errors).
• Yes, I've tried with the standalone linter if available (e.g., gocritic, go vet, etc.). (https://golangci-lint.run/usage/linters/)

Description of the problem

I searched for similar issues, but it is pretty subtle so I can't tell for sure. Feel free to close as duplicate.

To reproduce, create a new folder 'testgolint', with a 'src' folder and two files: go.main and go.mod:

➜  testgolint ls -R
src

./src:
go.mod  main.go

Run the linter:

➜  testgolint golangci-lint run src/...
ERRO [linters_context] typechecking error: pattern ./src/...: directory prefix src does not contain main module or its selected dependencies

➜  testgolint golangci-lint run src    
ERRO Running error: context loading failed: no go files to analyze

env:

➜  testgolint go env GOPATH
/Users/xyz/go

➜  testgolint go version 
go version go1.20.4 darwin/arm64

Version of golangci-lint

$ golangci-lint --version

➜  testgolint golangci-lint --version
golangci-lint has version 1.55.2 built with go1.21.3 from e3c2265f on 2023-11-03T12:59:25Z

Hey, thank you for opening your first Issue ! 🙂 If you would like to contribute we have a guide for contributors.

also tried Go 1.21:

➜  testgolint go version
go version go1.21.4 darwin/arm64

same results

[bombsimon]

I cannot reproduce this on macOS 14 with go1.21.3 darwin/amd64

› mkdir -p testgolint/src
› cd testgolint/src
› go mod init x
go: creating new go.mod: module x
› echo "package main\n\nvar i = 1" > main.go
› cd ..
› golangci-lint run --no-config --disable-all --enable gochecknoglobals ./src/...
src/main.go:3:5: i is a global variable (gochecknoglobals)
var i = 1
    ^

What's in your main.go?

[stephanwesten]

main is close to empty:

package main

func main() {

}

My real project - with the same problem - has a realistic impl - that how ran into this.

Note that if I navigate into src, there is no error:

➜  src golangci-lint run 
➜  src 

(I tried adding a dummy assignment into main and indeed get a linter error)

Somehow locating the src folder gives issues.

[stephanwesten]

So it seems something specific to my setup, perhaps this gives a clue:

[stephanwesten]

module is different:

➜  src cat go.mod
module testgolint

[ldez]

If your project follows this:

.
└── src
    ├── go.mod
    └── main.go

and you try to run golangci-lint at the root (.) of this structure, the behavior is expected because you are outside the module.

$ golangci-lint run
ERRO [linters_context] typechecking error: pattern ./...: directory prefix . does not contain main module or its selected dependencies 
$ golangci-lint run src/...
ERRO [linters_context] typechecking error: pattern ./src/...: directory prefix src does not contain main module or its selected dependencies 

[stephanwesten]

Okay, not supported is a design decision.

I did not expect this as I can build using -C specifying a source folder. I expected the linter to follow the same paradigm.

I failed to understand the error message because of the word 'prefix' in 'directory prefix src'. I took this literal as that 'src' was used as a prefix in a search.

The error message also feels more like an internal error as a user error. I suggest to add something like 'please specify a valid source path'

The error message comes from Go itself:

• https://github.com/golang/go/blob/1cc19e5ba0a008df7baeb78e076e43f9d8e0abf2/src/cmd/go/internal/modload/load.go#L497-L505
• https://github.com/golang/go/blob/1cc19e5ba0a008df7baeb78e076e43f9d8e0abf2/src/cmd/go/internal/modload/load.go#L634

The behavior is not a real design decision but just how the Go tooling works.
