Summary

We updated to Rush 5.109.1 yesterday, from 5.88.2. Since then, one of our CI pipelines has been throwing the following error on the rush build command (this is with --debug added):

Executing a maximum of 16 simultaneous processes...
Error: Error: Build cache is only supported if running in a Git repository. Either disable the build cache or run Rush in a Git repository.

Repro steps

Currently only occurs on a single one of our pipelines. All the others work fine. No devs have complained about their local machines.

Details

  • I see this particular error message was added recently with the following cobuild PR on Aug 31st.
  • I attempted to temporarily mitigate the problem by disabling the cache but the same error still occurs. [N.B. I tried multiple different ways through ENV vars, but also explicitly setting buildCacheEnabled to false in build-cache.json]

Standard questions

Any tips on how to debug this or information I could supply that would help?

Question Answer
@microsoft/rush globally installed version? N/A
rushVersion from rush.json? 5.109.1
useWorkspaces from rush.json? Not defined
Operating system? Linux (I think)
Would you consider contributing a PR? Sure
Node.js version (node -v)? 18.17.1

Never mind, apologies. We were doing something wild and woolly on that particular pipeline and copying the checked out repo into a separate folder. That was failing to copy over hidden files + this problem appeared after the Rush upgrade. (Amazing it worked before, quite frankly).
