Disable build cache for tagged builds

When a tagged build occurs, I don't want to pollute the main build cache.

A) Are build caches per matrix separate (like 64 vs. 32-bit)
B) Can I 'opt-out' of uploading the new cache for a tagged commit (or is there any mechanism to opt-out of overwriting the cache)

   Hi Nathanael,

   We do not see easy way to do this currently. Do you think if we introduce "tweak" environment variable APPVEYOR_SKIP_BUILD_CACHE_SAVE, which if set to true makes build process skip cache saving. Therefore you will be able to add statement like IF ($env:APPVEYOR_REPO_TAG -eq $true) {$env:APPVEYOR_SKIP_BUILD_CACHE_SAVE = $true} or even simple $env:APPVEYOR_SKIP_BUILD_CACHE_SAVE = $env:APPVEYOR_REPO_TAG.

   Alongside with this we can add APPVEYOR_SKIP_BUILD_CACHE_RESTORE for similar scenarios but related to cache restore.

   What do you think?
   Ilya.

   That sounds perfect! What about question A?

   OK, good, please watch this GH issue. It should not take long to implement.

   Sorry for missing question A. Can you elaborate it a little bit more? Does it mean you need to set different cache folders depending on matrix dimension?

   Different cache based on x86 or x86_64, in my case.

   Hope understand the problem correctly. Do you think something like this could help?

   platform:
   - x86
   - x64
   
   init:
   - if "%PLATFORM%"=="x86" SET CACHE_FOLDER=C:\FOO
   - if "%PLATFORM%"=="x64" SET CACHE_FOLDER=C:\BAR
   
   cache: $(CACHE_FOLDER)

   Wouldn't that just alterate deleting the other (missing) dir? I'd hope for
   something like CACHE_KEY where it just changes the cloud storage slot.

   Nathanael, sorry for confusion, I misunderstood your question. Yes, build caches per matrix separate, they are separated by job name.
