  • Method Details

    • handle

      void handle(Throwable error, Consumer<Throwable> defaultTrace)
      Handles an error that escaped command execution. UserInterruptException and EndOfFileException are not delivered here; Main treats those as control flow. A handler that throws is not caught again: the error escapes the REPL loop and Main.start(GroovyshOptions, String[]) returns 1.
      Parameters:
      error - the thrown error or exception
      defaultTrace - groovysh's own renderer, for a handler that wants to delegate
