The Material team is building Zensical as a replacement, but v9.x remains stable and is the correct choice now. MkDocs 9.7.6 is in maintenance mode but receives bug fixes through at least November 2026 — it is the right choice for this phase. + +**Primary recommendation:** Use `mkdocs-material==9.7.6` pinned in a `docs/requirements.txt`.

Alternatively, place CNAME in `docs/docs/CNAME` and add it to `mkdocs.yml` under `extra_files`. + +The correct location for MkDocs is `docs/docs/CNAME` (inside the docs source dir), or set `extra_files: [CNAME]` in `mkdocs.yml` pointing to a file at the `docs/` root. + +**Cloudflare DNS:** Create a CNAME record `java` → `amikos-tech.github.io` with proxy **disabled** (DNS-only, grey cloud). GitHub Pages must provision the Let's Encrypt cert directly. + +### Anti-Patterns to Avoid + +- **EthicalAds without the JS/CSS files:** chroma-go references `javascripts/ethicalads-init.js` and `stylesheets/ethicalads.css`. These files must exist or MkDocs build will fail. Either include them or omit EthicalAds from the config. +- **Running `mkdocs gh-deploy` from repo root when mkdocs.yml is in `docs/`:** Always pass `--config-file docs/mkdocs.yml` or `cd docs && mkdocs gh-deploy`. +- **Snippets `base_path` mismatch:** `base_path` is evaluated relative to the MkDocs `docs_dir` (the `docs/docs/` folder), not relative to `mkdocs.yml`. Test with `mkdocs build` locally first. +- **Using `peaceiris/actions-gh-pages` without `keep_files: true`:** Without this flag, the action wipes the entire `gh-pages` branch, destroying the MkDocs output deployed earlier in the same workflow. +- **Pinning `mkdocs-material` without a `requirements.txt`:** Using `pip install mkdocs-material` without a pinned version causes non-reproducible builds. +- **maven-javadoc-plugin 2.9.1 (current in pom.xml):** This is 10+ years old. Upgrade to 3.11.2 for Java 8 compatibility and proper HTML output.

The snippet files live in `docs/assets/snippets/` and can be compiled/tested independently. + +## Common Pitfalls + +### Pitfall 1: MkDocs 2.0 Confusion + +**What goes wrong:** Developer sees MkDocs 2.0 pre-release and attempts to use it; Material for MkDocs is incompatible with MkDocs 2.0. +**Why it happens:** MkDocs 2.0 announcement (Feb 18, 2026) is prominent; version 2.0 drops plugins and changes YAML→TOML config format. +**How to avoid:** Pin `mkdocs-material==9.7.6` in `requirements.txt`. MkDocs 1.x is installed as a transitive dependency of mkdocs-material and will be the correct version. +**Warning signs:** Error messages about "plugins not found" or TOML parse errors when building. + +### Pitfall 2: Javadoc Deployment Wiping MkDocs Output + +**What goes wrong:** Using `peaceiris/actions-gh-pages` for Javadoc without `keep_files: true` deletes the MkDocs HTML from `gh-pages` branch. +**Why it happens:** `peaceiris/actions-gh-pages` replaces the entire publish branch by default. +**How to avoid:** Always set `keep_files: true` when using `destination_dir` to deploy to a subfolder alongside other content. +**Warning signs:** After workflow run, the site root shows only Javadoc, guide pages return 404. + +### Pitfall 3: CNAME File Lost on Redeploy + +**What goes wrong:** Custom domain `java.chromadb.dev` breaks after each docs deployment because GitHub's CNAME setting is overwritten. +**Why it happens:** `mkdocs gh-deploy --force` rebuilds the `gh-pages` branch from scratch; if CNAME isn't in the site output, it gets deleted. +**How to avoid:** Place `CNAME` (containing `java.chromadb.dev`) inside `docs/docs/` so MkDocs copies it into the site output, or use `extra_files` in mkdocs.yml. +**Warning signs:** Custom domain disappears from GitHub Pages settings after each deploy. + +### Pitfall 4: Snippets Base Path Resolution + +**What goes wrong:** `--8<-- "MyExample.java"` fails to find the file at build time. +**Why it happens:** `base_path` in `pymdownx.snippets` config is evaluated relative to the MkDocs `docs_dir` (typically `docs/docs/`), not relative to `mkdocs.yml`. +**How to avoid:** Set `base_path: assets/snippets/` in mkdocs.yml, and place snippet files at `docs/docs/assets/snippets/`. Test locally with `mkdocs build --config-file docs/mkdocs.yml`. +**Warning signs:** `FileNotFoundError` or `SnippetMissing` error during `mkdocs build`. + +### Pitfall 5: Cloudflare Proxy Blocks SSL Provisioning + +**What goes wrong:** `java.chromadb.dev` shows Cloudflare error page; HTTPS doesn't work. +**Why it happens:** GitHub Pages provisions Let's Encrypt certificates by validating the domain directly. Cloudflare proxy (orange cloud) intercepts the ACME challenge. +**How to avoid:** Set the CNAME DNS record to DNS-only mode (grey cloud / proxy disabled) in Cloudflare. +**Warning signs:** GitHub Pages settings show "Not yet" for HTTPS; domain shows Cloudflare 525 error. + +### Pitfall 6: maven-javadoc-plugin Version 2.9.1 + +**What goes wrong:** Javadoc HTML generation produces malformed or unstyled output; may fail on newer Java. +**Why it happens:** The current pom.xml has version 2.9.1 (released ~2013). Version 3.x is required for modern HTML output. +**How to avoid:** Upgrade to `maven-javadoc-plugin` 3.11.2 in pom.xml for the `javadoc:javadoc` goal (keep `attach-javadocs` execution for Maven Central deployment). +**Warning signs:** Javadoc HTML missing navigation frames or showing render errors. + +## Code Examples + +Verified patterns from official sources: + +### GitHub Actions Docs Workflow (complete) + +```yaml +# Source: https://squidfunk.github.io/mkdocs-material/publishing-your-site/ +name: docs +on: + push: + branches: + - main + workflow_dispatch: + +permissions: + contents: write + +jobs: + deploy: + runs-on: ubuntu-latest + steps: + - uses: actions/checkout@v4 + with: + fetch-depth: 0 + + - name: Configure Git Credentials + run: | + git config user.name github-actions[bot] + git config user.email 41898282+github-actions[bot]@users.noreply.github.com + + - uses: actions/setup-python@v5 + with: + python-version: 3.x + + - run: echo "cache_id=$(date --utc '+%V')" >> $GITHUB_ENV + + - uses: actions/cache@v4 + with: + key: mkdocs-material-${{ env.cache_id }} + path: ~/.cache + restore-keys: | + mkdocs-material- + + - run: pip install -r docs/requirements.txt + + - name: Deploy MkDocs site + run: mkdocs gh-deploy --force --config-file docs/mkdocs.yml + + - uses: actions/setup-java@v4 + with: + java-version: '8' + distribution: 'temurin' + cache: maven + + - name: Generate Javadoc + run: mvn --no-transfer-progress compile javadoc:javadoc + + - name: Deploy Javadoc to /api/ + uses: peaceiris/actions-gh-pages@v4 + with: + github_token: ${{ secrets.GITHUB_TOKEN }} + publish_dir: ./target/site/apidocs + destination_dir: api + keep_files: true +``` + +### Snippet Named Section Marker (in Java snippet file) + +```java +// Source: https://facelessuser.github.io/pymdown-extensions/extensions/snippets/ +// docs/docs/assets/snippets/QuickstartExample.java + +// --8<-- [start:build-client] +Client client = ChromaClient.builder() + .baseUrl(System.getenv("CHROMA_URL")) + .build(); +// --8<-- [end:build-client] + +// --8<-- [start:add-records] +collection.add() + .documents("Hello, world.") + .ids("id-1") + .execute(); +// --8<-- [end:add-records] +``` + +### Snippet Inclusion in Markdown + +````markdown + +```java +--8<-- "QuickstartExample.java:build-client" +``` +```` + +### maven-javadoc-plugin 3.x in pom.xml + +```xml + + + org.apache.maven.plugins + maven-javadoc-plugin + 3.11.2 + + + attach-javadocs + + jar + + + + + 8 + none + + +``` + +### CNAME File Location + +``` +# Placed at: docs/docs/CNAME +java.chromadb.dev +``` + +## State of the Art + +| Old Approach | Current Approach | When Changed | Impact | +|--------------|------------------|--------------|--------| +| MkDocs 1.x plugins ecosystem | MkDocs-material 9.7.x (stable / maintenance mode) | Feb 2026: MkDocs 2.0 pre-release incompatible with Material | Pin to 9.7.6; do not upgrade to MkDocs 2.0 | +| `--8<-- filename.ext` (whole file) | Named sections `--8<-- [start:x]` / `--8<-- [end:x]` | pymdownx 9.7 | Can include sub-sections of Java files, not just full files | +| maven-javadoc-plugin 2.9.1 | 3.11.2 | 2.9.1 released ~2013, 3.x is current | Must upgrade for modern HTML output and Java 8+ proper support | +| Manual `git push` to gh-pages | `mkdocs gh-deploy --force` + `peaceiris/actions-gh-pages@v4` | GitHub Actions ecosystem matured | Standard pattern; co-deploy javadoc via `destination_dir` + `keep_files: true` | + +**Deprecated/outdated:** + +- `maven-javadoc-plugin 2.9.1`: Current pom.xml version is ancient; upgrade to 3.11.2. +- `actions/setup-java@v3` with `adopt` distribution: Project already uses `@v4` with `temurin` — consistent. +- EthicalAds: chroma-go includes it; adding it to Java docs is Claude's discretion — skip unless user confirms the ad placement account exists. + +## Open Questions + +1. **Google Analytics Property ID** + - What we know: chroma-go uses `G-NNN722BJKE` + - What's unclear: Does the Java client get the same GA property or a separate one? + - Recommendation: Use a placeholder `G-XXXXXXXXXX` in the scaffold; leave a TODO comment for the user to fill in. + +2. **EthicalAds Integration** + - What we know: chroma-go includes `ethicalads-init.js` and `ethicalads.css` + - What's unclear: Does the user want EthicalAds on the Java docs site? + - Recommendation: Omit EthicalAds from the initial scaffold (Claude's discretion per context).
