Elixir and breakage on Travis

Development on Elixir is still moving at break neck speed and currently they have bumped up their Erlang version to support RB17-r1 for the map support.

There is a lot of delicious goodness that will eventually come but this also causes a lot of fun breakage on Travis and Drone.io if you test your projects there.

Currently while Travis supports RB17-r1 in their otp_release, you might want to choose not to test your apps against that. If that is the case, you can change your .travis.yml from using trunk to using a release by changing the steps a little bit:

otp_release:

- R16B03-1

before_install:

- git clone git://github.com/elixir-lang/elixir

- cd elixir && make && cd ..

before_script:

- "export PATH=`pwd`/elixir/bin:$PATH"

- export PATH=`pwd`/elixir/bin:$PATH

- MIX_ENV=test mix do deps.get

script:

- MIX_ENV=test mix test   To:   otp_release: - R16B02 before_install: - wget -c https://github.com/elixir-lang/elixir/archive/v0.12.5.tar.gz - tar -xvzf v0.12.5.tar.gz - cd elixir-0.12.5 && make && cd .. before_script: - export PATH=`pwd`/elixir-0.12.5/bin:$PATH - MIX_ENV=test mix do deps.get - MIX_ENV=test mix do deps.compile script: - MIX_ENV=test mix amrita --trace     The drone.io settings should be something similar.    Found a better way of doing this which is you don't really have to use the manual wget method but you can just clone the repo then check out a branch within it. That way you don't have to tangle with all the version string messiness. Check out my final version: https://raw.githubusercontent.com/lowks/Radpath/master/.travis.yml
