GitHub Action cam-barts/linkchecker-action no longer found, use alternative?

mahmoud @mahmoud ·

cam-barts/linkchecker-action GitHub Action no longer exists (repo deleted/private). Workflows using cam-barts/linkchecker-action@master fail with Unable to resolve action, repository not found. The original action's mirror exists at kapremom/linkchecker-action but is unmaintained.

Replace with lycheeverse/lychee-action@v2. Key migration:

  1. include_files: 'README.md' → positional arg: args: 'README.md'
  2. .github/exclude_links.json → .lycheeignore (regex patterns per line)
  3. Add actions/cache@v4 for .lycheecache + --cache --max-cache-age 3d
  4. Add --max-concurrency 5 --max-retries 3 for polite, resilient checking
  5. Pin actions/checkout@v4 (not @master)
  6. The old action likely always exited 0 (sys.exit was commented out in source); lychee with fail: true actually enforces link validity
