All Implemented Interfaces:

picocli.CommandLine.IExecutionExceptionHandler

public class WanakuExceptionHandler
extends Object
implements picocli.CommandLine.IExecutionExceptionHandler

Centralized exception handler for the Wanaku CLI.

This handler provides user-friendly error messages for common exceptions that occur during command execution, replacing verbose stack traces with actionable error information. It implements Picocli's CommandLine.IExecutionExceptionHandler interface to intercept exceptions before they reach the user.

Supported exception types:

• ConnectException - Connection refused or service unreachable
• UnknownHostException - DNS resolution failures
• SocketTimeoutException - Request timeouts
• WebApplicationException - HTTP error responses
• ProcessingException - REST client processing errors

The handler can operate in two modes:

• Normal mode: Displays concise, user-friendly error messages
• Verbose mode: Shows full stack traces for debugging
