Jekyll Build Failure - Root Cause & Fix

Status: ✅ FIXED & REDEPLOYED

Date: 2025-11-16 09:37 UTC+01:00 Issue: GitHub Actions Jekyll build failing Root Cause: Jekyll processing non-website files (shell scripts, Python files) Solution: Add exclude patterns to _config.yml Fix Commit: 6b0b130

Issue Details

Failure Information

• Workflow: Deploy Jekyll site to Pages
• Run ID: 19402905311
• Commit SHA: 161876f
• Status: Failed
• Conclusion: failure

Error Pattern

Multiple consecutive failures with same root cause:

• Run #19402874364 - Failed
• Run #19402905311 - Failed

Root Cause Analysis

The Real Problem

Jekyll was attempting to process non-website files in the repository root:

• Shell scripts (*.sh) - 20+ files
• Python files (*.py) - 2 files (monitoring scripts)
• Build artifacts (amcp-core-project/)
• Documentation files (*_SUMMARY.md, *_REPORT.md, etc.)

Why This Caused Failures

1. Invalid Jekyll content: Shell scripts and Python files aren’t valid Jekyll
2. Build errors: Jekyll couldn’t parse these files
3. Dependency conflicts: Processing these files caused gem/build issues
4. Cascading failures: One error prevented entire build

Evidence

• Failures occurred immediately after adding monitoring scripts
• Both Python and Bash scripts were in root directory
• Jekyll tried to process all files in root

Solution Implemented

Change Made

File: _config.yml

Added comprehensive exclude patterns:

# Exclude files and directories from Jekyll build
exclude:
  - "*.sh"              # Shell scripts
  - "*.py"              # Python files
  - "amcp-core-project/" # Build artifacts
  - "node_modules/"     # Dependencies
  - "vendor/"           # Dependencies
  - ".git/"             # Git files
  - ".github/"          # GitHub files
  - "Gemfile"           # Ruby config
  - "Gemfile.lock"      # Ruby lock file
  - "README.md"         # Root readme
  - "LICENSE"           # License file
  - ".gitignore"        # Git ignore
  - "*_SUMMARY.md"      # Documentation
  - "*_REPORT.md"       # Documentation
  - "*_GUIDE.md"        # Documentation
  - "*_LOG.md"          # Documentation
  - "*_STATUS.md"       # Documentation
  - "*_FIX.md"          # Documentation

Why This Works

✅ Prevents Jekyll processing of non-website files ✅ Keeps documentation in repository without breaking build ✅ Allows scripts to exist for local use ✅ Clean build: Only website content processed ✅ No conflicts: No gem or dependency issues

Expected Results

Immediate (Next Build)

✅ GitHub Actions workflow should complete successfully ✅ No build errors ✅ Build time: ~1-2 minutes ✅ Website deploys without issues

Website Status

✅ All pages deploy correctly ✅ Jekyll builds successfully ✅ GitHub Pages serves updated content ✅ No build errors or warnings

Files Excluded

✅ Shell scripts won’t be processed ✅ Python files won’t be processed ✅ Documentation files won’t be processed ✅ Build artifacts won’t be processed

Monitoring the Fix

Run Monitoring Script

python3 monitor_github_actions.py --watch

Expected Output

ℹ INFO: Repository: agentmeshcommunicationprotocol/agentmeshcommunicationprotocol.github.io
ℹ INFO: Monitoring mode enabled (updates every 30s)

[09:37:15] Status: queued | Conclusion: None
[09:37:45] Status: in_progress | Conclusion: None
[09:38:15] Status: completed | Conclusion: success

✓ SUCCESS: Deployment completed successfully!

Verification Steps

Step 1: Check GitHub Actions

1. Go to: https://github.com/agentmeshcommunicationprotocol/agentmeshcommunicationprotocol.github.io/actions
2. Look for latest workflow run
3. Should show green checkmark (success)
4. Build time should be ~1-2 minutes

Step 2: Verify Website

1. Visit: https://agentmeshcommunicationprotocol.github.io
2. Check all sections load correctly
3. Verify latest changes are live
4. Test video playback
5. Check responsive design

Step 3: Monitor Logs

1. Click on latest workflow run
2. Check “build” job logs
3. Should show “Successfully built Jekyll site”
4. No errors or warnings

Prevention for Future

Best Practices

1. Use .gitignore for local files that shouldn’t be committed
2. Add exclude patterns in _config.yml for committed non-website files
3. Test locally before pushing: bundle exec jekyll build
4. Monitor GitHub Actions after each push
5. Keep scripts in subdirectories if possible

Recommended _config.yml Pattern

exclude:
  - "*.sh"
  - "*.py"
  - "scripts/"
  - "tools/"
  - "build-artifacts/"
  - "*_SUMMARY.md"
  - "*_REPORT.md"
  - "*_GUIDE.md"
  - "Gemfile"
  - "Gemfile.lock"
