[Bug]: bazel test //examples/npm_deps:test10 fails on windows with bazel 8+ #2261
Description
What happened?
We have an issue in our repo that prevents any of our tests from running. I have found the same issue in rules_js itself. It appears to have regressed between bazel 7.6.1 and bazel 8.0.0 and is still failing with bazel 8.3.1 and coincidentally perhaps I have noticed that the node symlinks were previously displayed as 'SYMLINKD' but in bazel 8.0.0+ are displayed as 'JUNCTION'
Setup:
git clone rules_js
%workspace%/windows.bazelrc:
# Enable platform specific config
common --enable_platform_specific_config
# Enable symlinks on windows
startup --windows_enable_symlinks
# Runfiles are disabled by default on Windows but rules_js requires them.
common:windows --enable_runfiles
Add to .bazelrc:
import %workspace%/windows.bazelrc
Update .bazelversion:
8.0.0
