* Decouple non-Mac builds from Xcode via BAZEL_NO_APPLE_CPP_TOOLCHAIN Set BAZEL_NO_APPLE_CPP_TOOLCHAIN=1 in .bazelrc so apple_support skips Xcode detection (xcode-locator) entirely for Scala/C++/Go builds. Only mactools builds (Mac/Sparkle) re-enable the Apple CC toolchain. This means Xcode version changes no longer affect Eagle, Shardok, test, auth, docker, or Unity Windows builds — no expunge, no cache invalidation, no rebuild. The sync script and its expunge/cache-key logic are now scoped to mactools only and removed from all non-Mac CI workflows. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * Revert BAZEL_NO_APPLE_CPP_TOOLCHAIN; keep Apple CC with stable environ BAZEL_NO_APPLE_CPP_TOOLCHAIN=1 broke builds because apple_support registers platforms (e.g. macos_x86_64) that require Apple CC toolchains for resolution — even in non-Mac builds. Instead, keep Apple CC enabled but ensure its repo rule never re-evaluates on non-Mac builds by keeping DEVELOPER_DIR pinned in common:macos. The sync script only runs for mactools builds and overrides DEVELOPER_DIR there.

# Keeps Bazel mactools builds in sync with the installed Xcode version.
|
|
#
|
|
# Only needed on runners that do mactools builds (Mac/Sparkle). Non-Mac builds
|
|
# don't run this script; their apple_cc_autoconf stays cached because none of
|
|
# its environ vars change, so they're unaffected by Xcode version changes.
|
|
#
|
|
# 1. Writes .bazelrc.xcode with mactools-scoped flags:
|
|
# - action_env for remote cache key invalidation
|
|
# - DEVELOPER_DIR pointing to the active Xcode
|
|
#
|
|
# 2. Runs `bazel clean --expunge` when the version actually changes, because
|
|
# local_config_apple_cc (a cached repository rule) bakes in the old version
|
|
# and can only be refreshed by clearing the output base.
|
|
#
|
|
# .bazelrc imports the generated file via: try-import %workspace%/.bazelrc.xcode
