function PluginManager::loadRepository

Load all plugins and installers from a repository

If a plugin requires another plugin, the required one will be loaded first

Note that plugins in the specified repository that rely on events that have fired prior to loading will be missed. This means you likely want to call this method as early as possible.

@phpstan-param ($isGlobalRepo is true ? null : RootPackageInterface) $rootPackage

Parameters

RepositoryInterface $repo Repository to scan for plugins to install:

Throws

\RuntimeException
