  **Locate deps edn sources**
  
  Configuration is stored in one or more "deps edn" maps. These are edn maps with the following top-level keys:
  
  * `:deps` - map of lib (symbol) to coordinate
  * `:paths` - vector of project source paths
  * `:aliases` - map of alias name to alias data
  * provider-specific keys for configuring dependency sources
  
  The Clojure tools look for 4 potential deps edn sources:
  
  * Root - part of the clj installation (a resource in the tools.deps library)
  * User - cross-project configuration (typically tools), usually found at `~/.clojure/deps.edn`
  * Project - the `deps.edn` in the current directory
  * Config data - a deps edn map passed on the command line
  
  **Check cache**
