TL;DR: If your AppVeyor build is running but not using the
you may need to reauthorize your account with GitHub at https://ci.appveyor.com/account.
While working on an update to Datadock I needed to add a new feature
to a library that I hadn't worked on for a while. The GitHub project for this library
is connected to AppVeyor for continuous integration. However although the AppVeyor build
triggered when I pushed my changes to the repo, the build was not running the scripts in
appveyor.yml file, but instead using the old configuration that I had initially created
through the AppVeyor UI.
Removing the old configuration in the UI didn't help (in fact it made matters worse),
the AppVeyor docs clearly state that the
appveyor.yml file will always override
the UI settings if the file is present in the root of the repository, so it was
a bit of a head-scratcher.
Thankfully I found this post
which pointed me in the correct direction. Due to the length of time since I had last updated
this particular project; the GitHub authorization for the project had become stale.
To fix it, I headed to the account settings page,
clicked on Authorizations and added an authorization for GitHub. On the next push
to the repository the build kicked in with the
appveyor.yml configuration. Win!
