Heeey! Thanks for the heads up in this! This helped me to fix my problem with a mix task test that was hiding mix messages from other apps in the same umbrella. Here is the topic I opened for the problem.
As you can see, I used Mix.shell(Mix.Shell.Process)
and had problems with the umbrella apps logs. Here is the code I used to fix it:
setup do
Mix.shell(Mix.Shell.Process)
on_exit fn ->
Mix.shell(Mix.Shell.IO)
end
:ok
end
If you could update your post with it, I guess it can be a very common problem for other people who like to make their own mix tasks.
