Add a comment for disabling errexit, try to debug appveyor cache Comments added as requested. Also, lets add some cache debugging to appveyor. I *think* this is how to ignore errors in cmd.exe (and I did try it on my own machine), but I'm not 100% sure how appveyor runs them. In the worst case it'll fail but I guess that isn't the end of the world since the build has already failed by this point. r? @TimNN
