尝试运行任务组合工作服时出现此错误。

我有3个以上的应用程序使用相同的工作服设置，并且在所有这些应用程序中都有效。唯一的区别是我没有HTML，因为它只是REST API，但是即使我尝试删除工作服html任务也无法正常工作。似乎可以使用erlang：cover进行编译，但是我尝试调试，并且它指向正确的目录。

这是我的Mix文件：

defmodule Tow.MixProject do
  use Mix.Project

  def project do
    [
      app: :tow,
      version: "0.1.0",
      elixir: "~> 1.8",
      compilers: [:phoenix] ++ Mix.compilers(),
      start_permanent: Mix.env() == :prod,
      test_coverage: [tool: ExCoveralls],
      preferred_cli_env: [
        coveralls: :test,
        "coveralls.detail": :test,
        "coveralls.post": :test,
        "coveralls.html": :test
      ],
      elixirc_paths: elixirc_paths(Mix.env()),
      deps: deps(),
      aliases: aliases()
    ]
  end

  # Run "mix help compile.app" to learn about applications.
  def application do
    [
      extra_applications: [:logger, :plug_cowboy],
      mod: {Tow.Application, []}
    ]
  end

  defp elixirc_paths(:test), do: ["lib", "test/support"]
  defp elixirc_paths(_), do: ["lib"]

  defp deps do
    [
      {:phoenix, "~> 1.4"},
      {:flow, "~> 0.14"},
      {:timex, "~> 3.1"},
      {:math, "~> 0.3.0"},
      {:plug_cowboy, "~> 2.0"},
      {:poison, "~> 3.1"},
      {:ecto_sql, "~> 3.0"},
      {:mariaex, "~> 0.8"},
      {:statistics, "~> 0.5.0"},
      {:elixir_uuid, "~> 1.2"},
      {:ex_aws, "~> 2.1"},
      {:ex_aws_s3, "~> 2.0"},
      {:config_tuples, "~> 0.2.0"},
      # dev / test
      {:benchee, "~> 1.0", only: :dev},
      {:phoenix_live_reload, "~> 1.0", only: :dev},
      {:ex_machina, "~> 2.2.2", only: :test},
      {:faker, "~> 0.10", only: :test},
      {:excoveralls, "~> 0.10", only: :test}
    ]
  end

  # Aliases are shortcuts or tasks specific to the current project.
  # For example, to create, migrate and run the seeds file at once:
  #
  #     $ mix ecto.setup
  #
  # See the documentation for `Mix` for more info on aliases.
  defp aliases do
    [
      "ecto.setup": ["ecto.create", "ecto.load", "ecto.migrate"],
      "ecto.reset": ["ecto.drop", "ecto.setup"],
      test: ["ecto.create --quiet", "ecto.migrate", "test"]
    ]
  end
end

问题出在erlang Cover库上，我的一个模块中有一个TypeSpec，由于某种原因无法编译。

为什么运行混合工作服时出现编译错误
