What version of gazelle are you using?

0.38.0

What version of rules_go are you using?

0.49.0

What version of Bazel are you using?

7.2.1

Does this issue reproduce with the latest releases of all the above?

yes

What operating system and processor architecture are you using?

Darwin ReficuldeMBP.reficul.lab 23.0.0 Darwin Kernel Version 23.0.0: Fri Sep 15 14:41:34 PDT 2023; root:xnu-10002.1.13~1/RELEASE_ARM64_T8103 arm64

What did you do?

I was following the official tutorial of go workspace with bzlmod. I created a demo project looks like below:

.
├── BUILD.bazel
├── MODULE.bazel
├── MODULE.bazel.lock
├── WORKSPACE
├── example
│   └── hello
│       ├── BUILD.bazel
│       ├── go.mod
│       └── reverse
│           ├── BUILD.bazel
│           ├── example_test.go
│           ├── int.go
│           ├── reverse.go
│           └── reverse_test.go
├── go.mod
├── go.sum
├── go.work
└── main.go

go.work looks like:

go 1.22.5

use (
        .
        ./example/hello
)

MODULE.bazel looks like:

module(
    name = "demo",
    version = "0.1.0",
)

bazel_dep(name = "rules_go", version = "0.49.0")
bazel_dep(name = "gazelle", version = "0.38.0")

go_sdk = use_extension("@rules_go//go:extensions.bzl", "go_sdk")

go_sdk.download(version = "1.22.3")

go_deps = use_extension("@gazelle//:extensions.bzl", "go_deps")

go_deps.from_file(
    go_work = "//:go.work",
)

use_repo(
    go_deps,
    "org_golang_x_example_hello",
)

In this demo, main.go imports example/hello/reverse by using go.work, and a new added function Int is called. This Int method is only existed in this local package. so if go.work works, building should success. if go.work doest work, then building should fail.

This demo works great by using go build, but fails by using bazel build //:demo. did anything I do wrong?

The demo project could be found in attachment: go-work.tar.gz

What did you expect to see?

building without any error.

What did you see instead?

friendly ping @stefanpenner

I haven't had much time for bazel stuff recently, but that might be changing. I'll attempt to carv out some time to investigate.

FWIW the go work demo was how I originally made this work, and I believe it inspired the tests within gazelle itself, so it is surprising to see a failure here.
