Build cache doesn't seem to work

Hello,

I'm using a build cache on c:\users\appveyor\pip\wheels but it seems that it's always empty.

I have this in the conf:

build: off
cache:
  - C:\Users\appveyor\pip\wheels -> tox.ini
matrix:
  fast_finish: true
environment:
  matrix: 
    ... long list of slow stuff here ...
init:
  - "echo %CTX%"
  - "set"
  - ps: "ls C:\Python*"
install:
  - ps: New-Item -Force -ItemType directory -Path "c:/Users/appveyor/pip/wheels"
  - ps: Copy-Item -Path "./ci/pip.ini" -Destination "c:/Users/appveyor/pip/pip.ini" -Force
  - ps: Invoke-WebRequest "https://bootstrap.pypa.io/ez_setup.py" -OutFile "c:\ez_setup.py"
  - ps: Invoke-WebRequest "https://bootstrap.pypa.io/get-pip.py" -OutFile "c:\get-pip.py"
  - "c:\python27\python c:\get-pip.py setuptools wheel"
  - "c:\python27\Scripts\pip wheel tox virtualenv cookiecutter bumpversion"
  - "c:\python27\Scripts\pip install -I -U tox virtualenv cookiecutter"
test_script:
  - git config --global user.email "[email blocked]"
  - git config --global user.name "Your Name"
  - powershell ci\test.ps1 $Env:ENV

The pip wheel tox virtualenv cookiecutter bumpversion always build the wheels so it must mean that c:/Users/appveyor/pip/wheels is empty.

Any idea what I'm doing wrong?

   Example build https://ci.appveyor.com/project/ionelmc/cookiecutter-pylibrary/buil...

   Yeah, that's strange. So, it's just that particular job?

   I've added some debugging info here:
   https://ci.appveyor.com/project/ionelmc/cookiecutter-pylibrary/build/develop-90/job/jek73nwjqkj2x7xj#L97

   You can see that the path doesn't exist. Any ideas what to do to make it
   work?

   The previous build said it saved the wheels:
   https://ci.appveyor.com/project/ionelmc/cookiecutter-pylibrary/build/develop-90/job/nx9m1ipgrghv7ct8#L508

   This indicates that the wheels were placed there:
   https://ci.appveyor.com/project/ionelmc/cookiecutter-pylibrary/build/develop-90/job/nx9m1ipgrghv7ct8#L161

   The build next to it says the cache was restored: https://ci.appveyor.com/project/ionelmc/cookiecutter-pylibrary/buil...

   The explanation is why the cache is not restored on some builds/jobs is that cache is stored in the same Azure region where build worker is running. For better reliability AppVeyor can create build workers in 3 regions (West US, Central US and East US). When provisioning time or the number of "unhealthy" build workers is increasing AppVeyor switches to a different region and there is no cache for that project yet (or it's outdated).

   I think this is most likely the change that makes it work:
   https://github.com/ionelmc/cookiecutter-pylibrary/commit/3728fabe84bb99e0601280aa5dcaab503a00aab9

   Maybe a bug after all? :-)

   Well, it just makes it tracking C:\Users\appveyor\pip\wheels for any changes to decide when the cache is invalidated.
