Clojure tools - merging conventions

[practicalli-johnny]

Update https://practicalli.github.io/clojure/clojure-tools/deps-edn-configuration.html

The Clojure tools look for 4 potential deps.edn sources:

• Root - found in the installation of clj (or as a resource in tools.deps)
• 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
