When using the Ruby plug-in with IntelliJ, what "undefined reference" warnings should I expect/tolerate, and which indicate that I don't have something configured correctly?
For example, I am getting "Cannot find" warnings for 'require', 'File', and 'FileUtils'. I suspect that this indicates a configuration problem.
I am also getting warnings for RSpec methods like 'describe', 'before', 'after, and 'it'. Should I also be able to configure IntelliJ to "find" these?

Press Shift twice to open the search window. By default, IntelliJ IDEA displays the list of recent files. Pressing double Shift again or Alt+N for mnemonics will select the Include non-project items checkbox and the list of search results will extend to non-project related items.
Ctrl+N: finds a class by name. Ctrl+Shift+N: finds any file or directory by name (supports CamelCase and snake_case ). If you have a directory or a file that you excluded from your project, IntelliJ IDEA will not include it in the search process. Ctrl+Alt+Shift+N: finds a symbol.
While IntelliJ IDEA is an IDE for Java, it also understands and provides intelligent coding assistance for a large variety of other languages such as SQL, JPQL, HTML, JavaScript, etc., even if the language expression is injected into a String literal in your Java code.
IntelliJ IDEA lists the results dividing them into sections where your query is found.Press Ctrl+Up or Ctrl+Down (⌘↑/⌘↓ on macOS) to jump between sections. Click to list the search results in the Find tool window. Press Tab to switch the scope of your search to classes, files, symbols, or actions.
You need to select the Ruby SDK in the Project Strucure (Ctrl + Alt + Shift + S by default).
Unfortunately it does not solve the warnings for rspec related words.
