Overview

This PR introduces a cleaner, more reliable, and consistent approach to error handling across the Harbor CLI. It standardizes parsing and reporting API errors, making the CLI more user-friendly and developer-maintainable.

Key Changes

• Added ParseHarborError utility

  • Centralized error parsing logic using reflection to extract the Payload from Harbor API responses.
  • Produces clean and readable error messages for users (e.g.,
    • "user not found field"
    • "permission denied field")

• Replaced Run with RunE across commands

  • Enables direct error returns from command handlers.
  • Ensures all errors are parsed through the new ParseHarborError function for consistent logging.

• Code cleanup and simplification

  • Removed redundant lines and unused logs.
  • Improved flow readability and reduced clutter in error blocks.

Motivation

• Prior CLI behavior often exposed raw Go structs or verbose pointers in error logs.
• This refactor ensures a consistent and user-friendly experience across all commands.
• Simplifies future debugging and maintenance.

Before:

Error: login failed: login failed, please check your credentials: [GET /users/current][401] getCurrentUserInfoUnauthorized  &{Errors:[0x14000158240]}

ERRO failed to delete user: [DELETE /users/{user_id}][404] deleteUserNotFound  &{Errors:[0xc00045a1a0]} 

After:

./bin/harbor-cli login demo.goharbor.io -u harbor-cli -p Harbor1234
Error: login failed: login failed, please check your credentials and server address, one of them is incorrect

rizul@rizu:~/OSS/harbor-cli$ ./bin/harbor-cli user delete 1123
