Can't use from Elixir #39

Closed stephanos closed 4 years ago

stephanos commented 4 years ago

I merely added 

{:opentelemetry, git: "git@github.com:open-telemetry/opentelemetry-erlang.git", tag: "master"},

to my Elixir project and when I run mix deps.compile, I see:

===> Compiling opentelemetry_api
===> vcs_vsn: Unknown vsn format: {file,"VERSION"}

Am I doing anything wrong?

PS: I'm using elixir 1.9.1 and erlang 22.0.5

Ah, I see the issue. Mix still uses a very old rebar3. Maybe we'll add a mix.exs to that repo as well to deal with it but for now you can fix this by manually updating the rebar3 mix uses:

A couple ways to do this are discussed at the end of this thread https://github.com/beam-telemetry/telemetry/issues/58

You can get the latest rebar3 here https://rebar3.s3.amazonaws.com/rebar3

Hopefully we'll be publishing 0.3.0 to hex soon, maybe even today and this issue will not exist when using the hex package.

Thanks for the swift response! I'll see if that workaround works for me. Yes, a hex package would be much appreciated :)

follow up: upgrading rebar did the trick!
