Execution of Task.AliasOrder failed on file with quoted alias within macro

[gerbal]

I'm getting the error Execution of the Recode.Task.AliasOrder task failed. when defining alias from quoted macro inputs. For example

defmodule RepoTestCase do
  defmacro __using__(opts) do
    repo = Keyword.fetch!(opts, :repo)

    quote do
      alias unquote(repo), as: Repo
    end
  end
end

Thanks for reporting this.

I can not reproduce it. I will take another look later. Which recode version your are using? I have made a new release some hours ago.

The issue is present for me in v0.4.4. The issue is persistent in the original code base, but I am unable to recreate it in a simple test case.

Here is the actual exception and stack trace being raised within Recode

There is a fix in the main branch. If you like you can give it a try.
