This directory contains a sophisticated set of GitHub workflows designed for the OSM Maker project, a Kotlin multiplatform application that processes OpenStreetMap data and generates 3D models.

🚀 Workflow Overview

Core Workflows

Workflow	File	Trigger	Purpose
CI/CD Pipeline	ci.yml	Push, PR, Manual	Comprehensive testing and building across platforms
Release Automation	release.yml	Tags, Manual	Automated releases with changelog generation
Documentation	docs.yml	Push to main, PR	API docs generation and GitHub Pages deployment
Dependency Updates	dependency-updates.yml	Weekly schedule, Manual	Automated dependency monitoring and updates
Performance Monitoring	performance.yml	Push, PR, Weekly	Build performance and artifact size analysis

Supporting Configuration

File	Purpose
dependabot.yml	Automated dependency updates via Dependabot

📋 Detailed Workflow Descriptions

1. CI/CD Pipeline (ci.yml)

Triggers: Push to main/develop, Pull requests, Manual dispatch

Features:

• Multi-platform testing on Ubuntu, Windows, and macOS
• Multiplatform builds for JVM and WASM targets
• Code quality analysis with detekt
• Security scanning with Trivy
• Dependency vulnerability checking with OWASP
• Artifact uploads for test results and build outputs
• Gradle caching for improved performance

Jobs:

1. test - Runs tests across multiple operating systems
2. build - Builds JVM and WASM artifacts
3. code-quality - Runs static code analysis
4. security-scan - Performs security vulnerability scanning
5. dependency-check - Checks for vulnerable dependencies

2. Release Automation (release.yml)

Triggers: Git tags (v*), Manual dispatch with version input

Features:

• Semantic version validation (v1.0.0 format)
• Automated changelog generation from git commits
• Multi-format distribution packages (tar.gz, zip)
• GitHub release creation with proper assets
• Pre-release detection for beta/alpha versions
• Release notifications

Jobs:

1. validate-release - Validates version format and extracts version info
2. build-release - Builds all targets and creates distribution packages
3. generate-changelog - Generates changelog from git history
4. create-release - Creates GitHub release with artifacts
5. notify-release - Sends success notifications

3. Documentation (docs.yml)

Triggers: Push to main (docs changes), Pull requests, Manual dispatch

Features:

• API documentation generation using Dokka
• GitHub Pages deployment with custom landing page
• Link validation for documentation quality
• Accessibility checks for generated documentation
• Automatic Dokka plugin integration

Jobs:

1. generate-docs - Generates API docs and creates documentation site
2. deploy-docs - Deploys to GitHub Pages (main branch only)
3. validate-links - Validates documentation links and accessibility

4. Dependency Updates (dependency-updates.yml)

Triggers: Weekly schedule (Monday 2 AM UTC), Manual dispatch

Features:

• Dependency update checking with detailed reports
• Security auditing with OWASP dependency check
• Automated PR creation for dependency updates
• Comprehensive reporting with recommendations
• Integration with Dependabot for coordinated updates

Jobs:

1. check-updates - Scans for available dependency updates
2. security-audit - Performs security audit of dependencies
3. create-update-pr - Creates PR with update reports (scheduled runs only)

5. Performance Monitoring (performance.yml)

Triggers: Push to main, Pull requests, Weekly schedule, Manual dispatch

Features:

• Build performance analysis with timing measurements
• Memory usage monitoring during builds
• Artifact size tracking for both JVM and WASM outputs
• Performance threshold validation with status indicators
• Automated PR comments with performance results
• Historical performance tracking

Jobs:

1. build-performance - Measures build times and generates performance reports
2. memory-analysis - Analyzes memory usage during builds
3. size-analysis - Tracks artifact sizes and provides optimization recommendations

🔧 Configuration Details

Dependabot Configuration

The dependabot.yml file configures automated dependency updates:

• Gradle dependencies: Weekly updates on Monday at 2:00 AM UTC
• GitHub Actions: Weekly updates on Monday at 2:30 AM UTC
• Intelligent grouping: Kotlin-related updates are grouped together
• Version constraints: Major Kotlin updates are ignored for stability
• Proper labeling: All PRs are labeled appropriately for easy identification

Environment Variables and Secrets

The workflows use the following environment variables and secrets:

Variable/Secret	Usage	Required
GITHUB_TOKEN	GitHub API access for releases and comments	✅ Auto-provided
GRADLE_OPTS	Gradle optimization settings	✅ Set in workflows

Performance Thresholds

The performance monitoring workflow uses these thresholds:

Metric	Threshold	Status
Clean Build	< 2 minutes (120s)	✅ Good / ⚠️ Slow
Incremental Build	< 30 seconds	✅ Good / ⚠️ Slow
Test Execution	< 1 minute (60s)	✅ Good / ⚠️ Slow
WASM Build	< 1.5 minutes (90s)	✅ Good / ⚠️ Slow

🎯 Best Practices Implemented

Security

• Vulnerability scanning with Trivy and OWASP
• Dependency security auditing with automated reporting
• Minimal permissions for workflow jobs
• Secure artifact handling with proper upload/download

Performance

• Gradle caching for faster builds
• Parallel job execution where possible
• Incremental builds for development efficiency
• Performance monitoring with automated alerts

Quality

• Multi-platform testing ensures compatibility
• Code quality gates with detekt integration
• Documentation validation with link checking
• Automated formatting and style checks

Automation

• Semantic versioning with automated validation
• Changelog generation from git history
• Dependency updates with security considerations
• Release automation with proper asset management

🚀 Getting Started

Prerequisites

1. Enable GitHub Pages in repository settings
2. Configure branch protection for main branch
3. Set up required secrets (if any custom ones are needed)
4. Review Dependabot settings and adjust reviewers/assignees

First Run

1. Push to main branch to trigger CI/CD pipeline
2. Create a tag (e.g., v1.0.0) to test release automation
3. Check GitHub Pages deployment for documentation
4. Review workflow runs in the Actions tab

Customization

To customize the workflows for your specific needs:

1. Update reviewer/assignee usernames in dependabot.yml
2. Adjust performance thresholds in performance.yml
3. Modify build targets in ci.yml if needed
4. Update documentation URLs in docs.yml

📊 Monitoring and Maintenance

Regular Tasks

• Review dependency update PRs weekly
• Monitor performance trends in workflow artifacts
• Update workflow versions when new actions are available
• Review security scan results and address vulnerabilities

Troubleshooting

Common issues and solutions:

1. Build failures: Check Gradle configuration and dependencies
2. Documentation deployment: Verify GitHub Pages settings
3. Performance degradation: Review performance reports and optimize
4. Security alerts: Address dependency vulnerabilities promptly

🤝 Contributing

When contributing to this project:

1. All PRs trigger the full CI/CD pipeline
2. Performance results are automatically commented on PRs
3. Documentation changes trigger doc regeneration
4. Security scans run on all changes

The workflows are designed to provide comprehensive feedback while maintaining development velocity.
