Hi,

I have an umbrella project containing two applications (one Phoenix, one plain Elixir), with dialyxir configured in the umbrella. It all worked fine until recently, when suddenly mix dialyzer started failing (see below for output). My problem is I can’t work out what changed to cause the failures – I’ve reverted to a version where I’m certain it used to work, and still get the same errors, so I assume it’s something external to the project. I’ve also tried removing the _build directory, and even ~/.mix, and in increasing desperation even reinstalling elixir and erlang, but nothing has helped so far.

I’m hoping someone can at least point me in the right direction to start looking for a solution, as I’m completely stumped (I’m a relative newcomer to the platform).

I’m using Elixir 1.4.0 on Erlang 19, and dialyxir 0.5.0, running on Mac OS 10.12.4. Here’s the output I get:

mix dialyzer --halt-exit-status
