How to execute custom task in mix releases step?
In mix.exs:

      releases: [
        myapp: [
          overwrite: true,
          include_executables_for: [:unix],
          steps: [:assemble, Mix.Task.run("mytask"), :tar]
        ]
      ]

Results in

** (Mix.NoTaskError) The task "mytask" could not be found

error.

But the mix mytask works fine.

I don’t know but I am calling a function in my steps this way:

steps: [&copy_datadog_files/1, :assemble]

and then I have defp copy_datadog_files(release) do ... in mix.exs file that defines such function. I guess you can execute Mix task from that function too, but I never tried it or know if there’s better way

Mix.task.run("mytask") tries to literally run the task at that very moment. It doesn’t return a value that is then added as a step.

I’ve moved it to function and it worked.
Thank you!

And thank you for your advice. Now I got it.
If I could, I would mark your post as a solution too :heart:
