I had the same problem, and it was an extension in VS Code calling Credo. Disabling it made recompile work again.

I did remove some Atom autocomplete-elixir package that was giving out an error. ‘recompile’ seems to be working fine now:

iex(46)>  recompile
Compiling 1 file (.ex)
warning: variable "muff" is unused (if the variable is not meant to be used, prefix it with an underscore)
  lib/cards.ex:41: Cards.bro/2

:ok
iex(47)>

Thanks guys!

Not sure if relevant but I had this vscode extension for “elixir linting” which I removed and then recompile started working again. Forgot which extension it was exactly.

Inotify-tools shouldn’t be required for mix compile to detect a change, should it? I thought it was only for hot recompiles for phoenix

For me, that’s about an hour in the future

Also please do not post screenshots. Instead copy and paste into the forum and use markdown code fences to mark your code.

For me, the following workflow triggers a rebuild, does it for you as well?

$ mix compile
...
$ touch lib/foo.ex
$ mix compile
...

Also, what editor are you using? Does it perhaps recompile on save? Vim with some “ale” plugin was known to cause exactly this kind of problems.
