View Source mix deps (Mix v1.12.0)

Lists all dependencies and their status.

Dependencies must be specified in the mix.exs file in one of the following formats:

{app, requirement}
{app, opts}
{app, requirement, opts}

Where:

app is an atom
requirement is a Version requirement or a regular expression
opts is a keyword list of options

For example:

{:plug, ">= 0.4.0"}
{:gettext, git: "https://github.com/elixir-lang/gettext.git", tag: "0.1"}
{:local_dependency, path: "path/to/local_dependency"}

By default, dependencies are fetched using the Hex package manager:

{:plug, ">= 0.4.0"}

By specifying such dependencies, Mix will automatically install Hex (if it wasn't previously installed) and download a package suitable to your project. Note Hex expects the dependency requirement to always be given and it will warn otherwise.

Mix also supports Git and path dependencies:

{:foobar, git: "https://github.com/elixir-lang/foobar.git", tag: "0.1"}
{:foobar, path: "path/to/foobar"}

And also in umbrella dependencies:

{:my_app, in_umbrella: true}

Path and in umbrella dependencies are automatically recompiled by the parent project whenever they change. While fetchable dependencies, like the ones using :git, are recompiled only when fetched/updated.

The dependencies' versions are expected to be formatted according to Semantic Versioning and the requirements must be specified as defined in the Version module.

Options

Below we provide a more detailed look into the available options.

Dependency definition options

:app - when set to false, does not read the app file for this dependency. By default, the app file is read
:env - the environment (as an atom) to run the dependency on; defaults to :prod
:compile - a command (string) to compile the dependency; defaults to a mix, rebar or make command
:optional - marks the dependency as optional. In such cases, the current project will always include the optional dependency but any other project that depends on the current project won't be forced to use the optional dependency. However, if the other project includes the optional dependency on its own, the requirements and options specified here will also be applied. Optional dependencies will not be started by the application.
:only - the dependency is made available only in the given environments, useful when declaring dev- or test-only dependencies; by default the dependency will be available in all environments. The value of this option can either be a single environment (like :dev) or a list of environments (like [:dev, :test])
:targets - the dependency is made available only for the given targets. By default the dependency will be available in all environments. The value of this option can either be a single target (like :host) or a list of environments (like [:host, :rpi3])
:override - if set to true the dependency will override any other definitions of itself by other dependencies
:manager - Mix can also compile Rebar, Rebar3 and makefile projects and can fetch sub dependencies of Rebar and Rebar3 projects. Mix will try to infer the type of project but it can be overridden with this option by setting it to :mix, :rebar3, :rebar or :make. In case there are conflicting definitions, the first manager in the list above will be picked up. For example, if a dependency is found with :rebar3 and :rebar managers in different part of the trees, :rebar3 will be automatically picked. You can find the manager by running mix deps and override it by setting the :override option in a top-level project.
:runtime - whether the dependency is part of runtime applications. If the :applications key is not provided in def application in your mix.exs file, Mix will automatically include all dependencies as a runtime application, except if runtime: false is given. Defaults to true.
:system_env - an enumerable of key-value tuples of binaries to be set as environment variables when loading or compiling the dependency

Git options (`:git`)

:git - the Git repository URI
:github - a shortcut for specifying Git repos from GitHub, uses :git
:ref - the reference to checkout (may be a branch, a commit SHA or a tag)
:branch - the Git branch to checkout
:tag - the Git tag to checkout
:submodules - when true, initialize submodules for the repo
:sparse - checkout a single directory inside the Git repository and use it as your Mix dependency. Search "sparse Git checkouts" for more information.

If your Git repository requires authentication, such as basic username:password HTTP authentication via URLs, it can be achieved via Git configuration, keeping the access rules outside of source control.

git config --global url."https://YOUR_USER:YOUR_PASS@example.com/".insteadOf "https://example.com/"

For more information, see the git config documentation: https://git-scm.com/docs/git-config#git-config-urlltbasegtinsteadOf

Path options (`:path`)

:path - the path for the dependency
:in_umbrella - when true, sets a path dependency pointing to "../#{app}", sharing the same environment as the current application

Hex options (`:hex`)

See the Hex usage documentation for Hex options.

Deps task

mix deps task lists all dependencies in the following format:

APP VERSION (SCM) (MANAGER)
[locked at REF]
STATUS

For dependencies satisfied by Hex, REF is the package checksum.

For dependencies satisfied by git, REF is the commit object name, and may include branch or tag information.

It supports the following options:

--all - lists all dependencies, regardless of specified environment
