伞形项目

关于伞形项目, 什么是伞形项目, 定义在这里

创建一个伞形项目

1
root@0b85dcd174f2:~/ejabberd/elixir# mix new umbrella_project --umbrella
* creating .gitignore
* creating README.md
* creating mix.exs
* creating apps
* creating config
* creating config/config.exs
Your umbrella project was created successfully.
Inside your project, you will find an apps/ directory
where you can create and host many apps:
    cd umbrella_project
    cd apps
    mix new my_app
Commands like `mix compile` and `mix test` when executed
in the umbrella project root will automatically run
for each application in the apps/ directory.

在伞形项目中运行的Mix任务,会对文件夹中的每一个子项目起作用.
