After a successful or unsuccessful run, the CLI returns an exit code from this list:
0: OK - The operation completed successfully.
1: Client creation error - There was an error launching the client process.
2: Configuration error - This could be due to an unreachable configuration file or a parameter set to an invalid value.
3: Problem while launching one of the commands - One of the commands failed to complete successfully. The console should provide information about what exactly failed.
4: Engine validity error - The client you are running is not compatible with the server. You should try to run the command RETRIEVE_ENGINE_PACKAGE to get the latest compatible package from the server.
