Hello everyone,

I wonder what might cause the build cache to be invalidated except for file changes?
First a job for each platform ubuntu, windows, macos is build for a regular commit. All succeed, this is fine.
Second, I tag that specific commit and push that to the github repo. This triggers a rebuild as configured, because it should be deployed to github, leading to a 'release' version. It is the same commit as before, but now tagged.
On ubuntu and macOS the previously build binaries configured with build cache are reused and thus need less time. But on Windows, the cache is invalidated for the exact same files(!)? Why, what do I miss here?

Regular commit build:
https://ci.appveyor.com/project/SASfit/sasfit/builds/45726481

New build with tag, same commit:
https://ci.appveyor.com/project/SASfit/sasfit/builds/45728469

How to get Windows to use the previously store cache items?

Thanks for any help or info!
Best wishes
Ingo
