###############################################################################

Bazel now uses Bzlmod by default to manage external dependencies.

Please consider migrating your external dependencies from WORKSPACE to MODULE.bazel.

For more details, please check bazelbuild/bazel#18958

"""Module for blablabuilder."""

module(
name = "blablabuilder",
version = "0.0.1",
)

bazel_dep(name = "rules_go", version = "0.50.1", repo_name = "io_bazel_rules_go")
bazel_dep(name = "gazelle", version = "0.38.0")

go_deps = use_extension("@gazelle//:extensions.bzl", "go_deps", isolate = True)
go_deps.from_file(go_mod = "//:go.mod")
use_repo(
go_deps,
"in_gopkg_yaml_v3",
)

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

Download an SDK for the host OS & architecture as well as common remote execution platforms.

go_sdk.download(version = "1.22.7")

and the golang is a simple main.go:

package main

import (
	"bytes"
	"os"

	"gopkg.in/yaml.v3"
)

func main() {
	f := os.Open(os.Args[1])
	var buf bytes.Buffer
	_ := yaml.NewDecoder(f)
}

build.bazel is

load("@gazelle//:def.bzl", "gazelle")

package(default_visibility = ["//visibility:public"])

# gazelle:prefix github.com/andyliuliming/blablabuilder
# gazelle:go_generate_proto false
gazelle(
    name = "gazelle",
    prefix = " github.com/andyliuliming/blablabuilder",
)

then when I run the
bazel run //:gazelle

it hangs forever.

I can't reproduce this on Bazel 7.2.1 (and also not on 7.3.1). Could you share a repo with a full reproducer?
