Solutions

1. Pass the Groovy script via standard input or as a file argument.
2. Use '-' as the script source to read from stdin explicitly.
3. Verify the script file path exists and is readable.

When it happens

Trigger: Raised when the groovy CLI command is invoked without a script argument and without script input on stdin.

Common situations: See trigger scenarios.
