Things I've done to Resolve

• I've tried 12.0 and 11 versions with no luck
• manually generated the BUILD.bazel file
• looked through all the issues related to this and couldn't find / understand a fix that would work

Here is a link to the open source project build file:

It looks like com_github_cespare_xxhash is not declared in your WORKSPACE file. You should be able to add it with:

bazel run //:gazelle -- update-repos github.com/cespare/xxhash

That will add something like this:

go_repository(
    name = "com_github_cespare_xxhash",
    commit = "48099fad606eafc26e3a569fad19ff510fff4df6",
    importpath = "github.com/cespare/xxhash",
)

You may need to run that command again for additional transitive dependencies.

This works great thanks!

Is there a way to avoid bazel run //:gazelle ... ignore some repos

I have some manual deps for c++ cmake (that also happen to have go) in

src/thirdparty/*

when I run bazel run //:gazelle it creates BUILD.bazel files in all transitive projects.

how do i set the default to ignore say all in //src/thirdparty/*

[jayconrod]

Gazelle can be configured using special comments in build files. In this case, # gazelle:exclude is probably what you need. In your top-level build file, you could write the comment below, and Gazelle won't recurse into that directory:

# gazelle:exclude src/thirdparty

At the moment, there's no way to give it a whitelist of directories, though that would probably be a useful feature.

Awesome thank you! it all works.
