Access project version within elixir application

Question

I have an elixir project with a defined version. How can I access this from within the running application.

in mix.exs

  def project do
    [app: :my_app         


        

Answer 1

Application.spec(:my_app, :vsn) works when the application is started. If you're in a Mix task and you don't need to start the application, in Elixir 1.8 you can use:

MyApp.MixProject.project |> Keyword.fetch!(:version)
