When the .mix folder is created?

Questions / Help

Elixir version: 1.8.1
ex_cldr version: 1.8.2

I’m using ex_cldr in my project. (https://github.com/kipcole9/cldr)
It has its own compile task Mix.Tasks.Compile.Cldr, and this task creates .compile.cldr file in manifest_path(by default build/(env)/.mix) folder.

But it fails because build/(env)/.mix folder is not exist.

Generated my_project app
** (File.Error) could not write to file "/Users/me/workspace/project/my_project/_build/dev/.mix/.compile.cldr": no such file or directory

When the manifest path folder is created?

This folder is not mandatory to be created for elixir projects. If it’s ex_cldr artifact - you probably should create an issue or migrate for newer version of the library.

@nallwhy opened an issue (thanks - I’m the author). Thats from a piece of legacy code of the old ex_cldr 1.x versions which had some architectural issues and an ugly cldr compiler which was replaced last year with the 2.x series that is a much better citizen.

I recommend migrating to ex_cldr version 2.x if you can. I think the only main reason you might not be able to would be if you also need ex_cldr_dates_times which is not yet on the 2.x release series. It will be soon now…
