Error when running on Erlang 19.0 / Elixir 1.3.3 about excoveralls

[parroty]

Thanks for the confirmation.
I'll be pushing to hex sometime later (as I'm out of the office today and don't have laptop access).

With 0.6.1 I tried on Windows 10, Debian Linux, and macOS Sierra. This error was present on all 3 OS-es, only it was showing before the coverage was shown. It never even got to show coverage.

I was using 0.6.1 and went to 0.5.7 and that fixed it for me.

EDIT: Posting my stacktrace since it's different than yours:

I discovered this happens when you install excoveralls as an archive and try to use it without having it as a dependency in the project too.

Thanks for the report (and sorry being not responsive).
These 2 issues seem to be similar ones, and I tried fix with the above commit (it's in master branch).

Actually, I haven't been able to reproduce the error in my local environment. Is it possible for you to try the fix? (Maybe it's like the following).

def deps do
  [ {:excoveralls, github: "parroty/excoveralls", only: :test} ]
end

If it's difficult to try, some details about conditions to reproduce is appreciated.

@parroty That fixed it, by the way. Plan on releasing it in 0.6.2 soon?

[dimitarvp]

Thanks for your confirmation as well. I'll be keeping an eye and upgrade to 0.6.2 when I see a new tag with that name released.

[parroty]

Pushed as v0.6.2. I'm closing this item, assuming both of the issue are fixed, but if there's remaining issue, please reopen this or open another one.

[dimitarvp]

Confirmed that the error is no longer there on a fresh install with a new project, specifying exactly version 0.6.2.

Thank you!
