无法调用任务“distillery.release”

Question

我正在研究几个不同的 How-Tos（项目中的主要内容以及通过 Google 搜索获得的几个）以部署代码，但我找不到解决这个 Could not invoke task "distillery.release": 1 error found! 问题的方法：

$ mix edeliver build release

BUILDING RELEASE OF HELLO_WORLD APP ON BUILD HOST

-----> Authorizing hosts
-----> Ensuring hosts are ready to accept git pushes
-----> Pushing new commits with git to: abc@company.com
-----> Resetting remote hosts to b8a7e8d2098b228f693352a0ebc59fa5c708f7a3
-----> Cleaning generated files from last build
-----> Updating git submodules
-----> Fetching / Updating dependencies
-----> Compiling sources
-----> Generating release
using mix to generate release
** (Mix) Could not invoke task "distillery.release": 1 error found!
--verbosity : Unknown option

A remote command failed on:

  abc@company.com

Output of the command is shown above and the command executed
on that host is printed below for debugging purposes:

FAILED with exit status 1:

    [ -f ~/.profile ] && source ~/.profile
    set -e
    cd /tmp/erlang/hello-world/builds
    if [ "mix" = "rebar" ]; then
      echo "using rebar to generate release"
      ./rebar   -f generate
    elif [ "mix" = "relx" ]; then
      echo "using relx to generate release"
      ./relx release
    elif [ "mix" = "mix" ]; then
      echo "using mix to generate release"
      MIX_ENV="prod" LINK_SYS_CONFIG="" LINK_VM_ARGS="" APP="hello_world" AUTO_VERSION="commit-count+git-revision+branch-unless-master" BRANCH="master" SKIP_RELUP_MODIFICATIONS="" RELUP_MODIFICATION_MODULE="" USING_DISTILLERY="" mix do release.version ,  distillery.release --verbosity=verbose
    fi

设置

• 二郎22
• Elixir 1.10.2（使用 Erlang/OTP 21 编译）

$ mix phx.new hello_world --no-ecto

mix.exs

...
  def application do
    [
      mod: {HelloWorld.Application, []},
      extra_applications: [:logger, :runtime_tools, :edeliver]
    ]
  end
...
  defp deps do
    [
      {:phoenix, "~> 1.4.16"},
      {:phoenix_pubsub, "~> 1.1"},
      {:phoenix_html, "~> 2.11"},
      {:phoenix_live_reload, "~> 1.2", only: :dev},
      {:gettext, "~> 0.11"},
      {:jason, "~> 1.0"},
      {:plug_cowboy, "~> 2.0"},
      {:edeliver, ">= 1.8.0"},
      {:distillery, "~> 2.1", warn_missing: false}
    ]
  end
...

.deliver/config

APP="hello_world" # name of your release

# The applicationis build here:
BUILD_HOST="www.hello-world.de" # host where to build the release
BUILD_USER="deployer" # local user at build host
BUILD_AT="/tmp/erlang/hello-world/builds" # build directory on build host

# Staging
STAGING_HOSTS=""
STAGING_USER=""

# This is the place where it's going to be hosted:
PRODUCTION_HOSTS="www.hello-world.de" # deploy / production hosts separated by space
PRODUCTION_USER="deployer" # local user at deploy hosts
DELIVER_TO="/home/deployer/phoenix-systems" # deploy directory on production hosts

AUTO_VERSION=commit-count+git-revision+branch-unless-master # https://github.com/edeliver/edeliver/wiki/Auto-Versioning


# For *Phoenix* projects, symlink prod.secret.exs to our tmp source
pre_erlang_get_and_update_deps() {
  local _prod_secret_path="/home/deployer/hello-world.prod.secret.exs"
  if [ "$TARGET_MIX_ENV" = "prod" ]; then
    __sync_remote "
      ln -sfn '$_prod_secret_path' '$BUILD_AT/config/prod.secret.exs'
    "
  fi
}

杂项：

$ mix do deps.get, compile
$ echo ".deliver/releases/" >> .gitignore
$ git init
$ git add -a
$ git commit -m "Setting up edeliver"

我将/home/deployer/hello-world.prod.secret.exs 复制到构建和生产服务器。

$ mix release.init
* creating rel/vm.args.eex
* creating rel/env.sh.eex
* creating rel/env.bat.eex
$ git add .
$ git commit -m "release config"

然后我启动 mix edeliver build release 并得到错误。

Answer 1

相关行是：

** (Mix) Could not invoke task "distillery.release": 1 error found!
--verbosity : Unknown option

因为--verbosity 选项在v2 中是deprecated。

每个酒厂的文件：

--verbosity 标志不再存在，请使用 --silent、--quiet 或 --verbose。

它看到无法识别的选项并失败。不幸的是，它恰好出现在 delivery 本身提供的 shell 脚本中（对吗？还是你的？）。

MIX_ENV="prod" [...] mix do release.version ,  distillery.release --verbosity=verbose

无论如何，构建服务器上似乎有些混乱。我不确定为什么会出现不一致，但也许完全清理会有所帮助。

Answer 2

解决方法很简单：

1. 运行mix distillery.init
2. .deliver/config 中的APP 变量必须与rel/config.exs 中的释放原子相同。

Answer 3

添加此文件后跟git add . && git commit -m "test" 可以解决问题。

解决 = 是一种解决方法。

rel/config

# Import all plugins from `rel/plugins`
# They can then be used by adding `plugin MyPlugin` to
# either an environment, or release definition, where
# `MyPlugin` is the name of the plugin module.
~w(rel plugins *.exs)

use Distillery.Releases.Config,
    # This sets the default release built by `mix distillery.release`
