Exception Handling

Exceptions happen from a user code whether it is intentional or not. This section describes how Spring Shell handles exceptions and gives instructions and best practices on how to work with it.

Many command line applications return an exit code which can be used by the running environment to differentiate if command has been executed successfully or not. In Spring Shell, this mostly relates to when a command is run in a non-interactive mode, meaning one command is always executed once with an instance of a spring-shell. Take a note that exit code always relates to non-interactive shell.
