Build failure from missing files when using --experimental_action_cache_store_output_metadata #13882
Description
Description of the problem / feature request:
When using --experimental_action_cache_store_output_metadata, which was introduced in 4e29042, you can get build failures when going from using a remote cache to not using one.
Bugs: what's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.
bazel build --remote_cache=grpc://... --remote_download_toplevel --experimental_action_cache_store_output_metadata -- //...
bazel build --remote_download_toplevel --experimental_action_cache_store_output_metadata -- //...The second command will fail with errors like this:
