Hi,

I have the exact same problem as described in this SO question... just for AppVeyor instead:

https://stackoverflow.com/questions/13503009/continuously-building-and-delivering-only-changed-components

Is that possible?

Cheers, Asger

   Hi Asger,

   Each AppVeyor build runs on fresh VM, which is being destroyed right after build finished. Therefore it will be always full build. Having fresh VM for each build gives you really clean test environment and more confidence that you will not have a "works on my machine" problem.

   With that being said, we have TeamCity-like mode, where you can install AppVeyor build agent on your own build server. It is described here. However this is available for Premium accounts only. Trial is free. But again, I would not trade ability to have clean environment for some build time.

   Another option which might work for you is like this:

   • Create separate AppVeyor projects for each your project within solution
   • Tune each AppVeyor project to work with custom YAML file
   • In each YAML file tune to build if only specific files or folders changed

   Note that you can easily become confused with having multiple YAML files, so please look at this SO discussion.

   Ilya.

   Hi Ilya, thank you for the quick reply.

   This is not for performance, but for a monorepo setup, so the second option with multiple yaml files and selecting a subset of files is great. I'll try that out.

   Thanks again!
