I want to update project_cache when Cargo.lock content changes. However, cache updates are skipped.
how to fix？

Welcome to the community!

I think there's a misunderstanding. With Cache keys, changes made in the pipeline build will not invalidate the existing cache. Therefore, what you're observing is expected behavior; the cache will only be invalidated if the changes were made via a commit. 

Custom caches can support file-based cache keys. File-based cache keys allow for the generation and restoration of caches based on a set of files. Any changes to those files would result in a new cache.

Basically, changes to the files, in this case Cargo.lock, through commit will then trigger a new cache to be uploaded.

I hope this helps.
