I always confuse myself as to whether the correct flags for java and the jshell are -cp or --classpath or --class-path or something else, so instead of trying to remember something like a normal human, I instead spent a few hours pulling this script together.

It automatically detects any variation of cp, classpath, and class-path flags in a series of command-line arguments, and concatenates all of the correct arguments to give you a nice, clean classpath. I hope it's useful!
