end

#save_project_name ⇒ Object

Save the project_name in .jets/info.yml if inferred Better to write the file here instead of within the Jets::Core::Config::Info class. Because Info assumes Jets.root is Dir.pwd We need to ensure it’s written to stage/code not the current project root.

#save_ruby_version ⇒ Object

Save by moving .ruby-version to .jets/ruby-version So it does not affect codebuild ruby version.
