Can't use module_override to override a repo fetched inside module extension

[peakschris]

Description of the bug:

We have a module extension that uses a repo rule with rctx.download to download an artifact. We use it from the top level MODULE.bazel as:

fetcher = use_extension("//src/repo/bazel/rules:fetcher_extension.bzl", "fetcher")
fetcher.artifact_with_plat(
     name = "artifact1",
     url = y
     hash = z
)
use_repo("artifact1")

This works fine. The artifact ends up in my extensions folder as +fetcher+artifact1

How do I then override this artifact using override_module? --override_module=artifact1=... does not work, and --override_module=+fetcher+artifact1=... does not work.

This will be solved by #23534.

[peakschris]

@fmeum excellent! Can #23534 be released in bazel 7.3.x or 7.4?

[fmeum]

It will be in 7.4.0.

Also, the flag you're looking for is actually --override_repository=+fetcher+artifact1=....

A fix for this issue has been included in Bazel 7.4.0 RC1. Please test out the release candidate and report any issues as soon as possible.
If you're using Bazelisk, you can point to the latest RC by setting USE_BAZEL_VERSION=7.4.0rc1. Thanks!
