rules_android + maven Toolchain issu reproduction

This is to reproduce a problem occurring when using rules_android and a maven repository via rules_jvm_external.

The issue is that, when using certain androidx Maven repositories, attempting to use the repository as a dependency results in the following error:

$ bazel build //src/main/java/com/example/bazel:greeter_activity --toolchain_resolution_debug='@bazel_tools//tools/android:sdk_toolchain_type' 
WARNING: Build option --toolchain_resolution_debug has changed, discarding analysis cache (this can be expensive, see https://bazel.build/advanced/performance/iteration-speed).
INFO: ToolchainResolution: Performing resolution of @@bazel_tools//tools/android:sdk_toolchain_type for target platform @@platforms//host:host

To Reproduce

1. Check out this repository
2. Ensure your ANDROID_HOME environment variable is set appropriately.
3. Execute: bazel build //src/main/java/com/example/bazel:greeter_activity

Ineffective changes

The following items have had no effect on fixing the build:

• Including the following in .bazelrc:

  common --android_sdk=@androidsdk//:sdk
  

• Including the following in MODULE.bazel:

  android_sdk_repository_extension = use_extension("@rules_android//rules/android_sdk_repository:rule.bzl", "android_sdk_repository_extension")
  use_repo(android_sdk_repository_extension, "androidsdk")
  register_toolchains("@androidsdk//:sdk-toolchain", "@androidsdk//:all")

Effective changes

Including the following line in WORKSPACE.bzlmod made it work:

android_sdk_repository(name = "androidsdk")

Notes

• This has been attempted on an M1 Macbook Pro running Sonoma 14.7.
• The Android App was lifted from the Bazel Android Tutorial example.
