Updates the given dependencies.

The given dependencies and the projects they depend on will be unlocked and updated to the latest version according to their version requirements.

Since this is a destructive action, updating all dependencies only occurs when the --all command line option is passed.

All dependencies are automatically recompiled after update.

mix deps.unlock + mix deps.get

Upgrading a dependency often requires the projects it depends on to upgrade too. If you would rather update a single dependency and not touch its children, you can explicitly unlock the single dependency and run mix deps.get:

$ mix deps.unlock some_dep
$ mix deps.get

Command line options

• --all - updates all dependencies
• --only - only fetches dependencies for given environment
• --target - only fetches dependencies for given target
• --no-archives-check - does not check archives before fetching deps
