#initialize(lockfile, dependencies, sources, unlock, ruby_version = nil, optional_groups = [], gemfiles = []) ⇒ Definition

How does the new system work?

  • Load information from Gemfile and Lockfile

  • Invalidate stale locked specs

  • All specs from stale source are stale

  • All specs that are reachable only through a stale dependency are stale.

  • If all fresh dependencies are satisfied by the locked

specs, then we can try to resolve locally.

Parameters:

  • lockfile (Pathname) —

    Path to Gemfile.lock

  • dependencies (Array(Bundler::Dependency)) —

    array of dependencies from Gemfile

  • sources (Bundler::SourceList)
  • unlock (Hash, Boolean, nil) —

    Gems that have been requested to be updated or true if all gems should be updated

  • ruby_version (Bundler::RubyVersion, nil) (defaults to: nil) —

    Requested Ruby Version

  • optional_groups (Array(String)) (defaults to: []) —

    A list of optional groups
