Description

Improved GitLab token authentication to support both Bearer and PRIVATE-TOKEN authentication patterns with automatic detection and fallback.

Changes Made:

• Smart Token Detection: Automatically detects token type and chooses appropriate authentication method:
  • CI_JOB_TOKEN: Uses Bearer authentication
  • Personal Access Tokens (glpat-*): Uses Bearer authentication
  • OAuth tokens (long alphanumeric): Uses Bearer authentication
  • Other tokens: Uses PRIVATE-TOKEN authentication
• Automatic Fallback: If authentication fails with 401 error, automatically retries with alternative method
• Updated GitlabClient: Applied same logic to GitlabClient class for consistency
• Comprehensive Documentation: Added detailed GitLab token configuration section to README
• Test Coverage: Added unit tests for authentication logic and integration tests for fallback mechanism

Benefits:

• Maximum Compatibility: Works with all GitLab token types and configurations
• Robust Authentication: Fallback mechanism ensures authentication succeeds even if initial detection is incorrect
• Zero Configuration: Automatically handles authentication without user intervention
• Better User Experience: Clear documentation and error handling

Public Changelog

Enhanced GitLab integration with intelligent token authentication that automatically detects and uses the appropriate authentication method (Bearer or PRIVATE-TOKEN) with automatic fallback for maximum compatibility across different GitLab configurations.
