Could not start application no such file or directory on Elixir 1.15.0

[SteffenDE]

Elixir and Erlang/OTP versions

Erlang/OTP 26 [erts-14.0.1] [source] [64-bit] [smp:10:10] [ds:10:10:10] [async-threads:1] [jit

also happens on 1.15.0 and Erlang/OTP 25.

Operating system

macOS

Current behavior

The first invocation of mix compile works, any subsequent mix commands lead to the error

** (Mix) Could not start application :included_app_one: {~c"no such file or directory", ~c"geolix.app"}

The issue occurs in an umbrella application, where app one includes a dependency as included_application and runtime: false and the second app depends on the first app. To reproduce, see: https://github.com/SteffenDE/elixir-include-umbrella-issue
Creating a release using rm -rf _build && mix release app creates a functional release that works as expected. Adding prune_code_paths: false does NOT fix the problem.

Expected behavior

Subsequent mix compile calls should work.

Can confirm that this solves the issue, thank you very much! 😃

@josevalim This issue still happens in the following case (the same repro repo can be used, changing the .tool-versions file to something > 1.15.0 if using asdf or similar):

mix deps.get
mix compile
mix compile
# all fine up to here
mix deps.clean geolix
mix deps.get

 ~/elixir-include-umbrella-issue (main)> mix deps.get
Resolving Hex dependencies...
Resolution completed in 0.007s
Unchanged:
  geolix 2.0.0
  geolix_adapter_mmdb2 0.6.0
  mmdb2_decoder 3.0.1
* Getting geolix (Hex package)
** (Mix) Could not load application :included_app_one: {~c"no such file or directory", ~c"geolix.app"}

After a deps.clean, deps.get fails. The only solution I found was to delete the _build folder.

Yep, I’m experiencing the same with an umbrella app that depends on fun_with_flags and shoves it inside :included_applications.

@whatyouhide this is fixed. Please run either on the main (or v1.15 branches) for a while to see if you catch any regressions. :)
