The published Kotlin API reference was still generated from adk-kotlin
0.5.0, so it described an API several releases behind what the docs tell
people to depend on.
Regenerating it required repairing the generator first. adk-kotlin now
runs Dokka in V2 mode, where the V1 `dokkaHtmlMultiModule` task refuses
to run at all, and V2 has no implicit multi-module aggregation: the root
project only collects modules that are declared as `dokka` dependencies,
which adk-kotlin does not do for itself. The script therefore appends
those declarations to its throwaway clone before invoking
`dokkaGenerateHtml`, and copies from the V2 output path.
The regenerated site adds four modules that did not exist at 0.5.0:
firebase, mlkit, examples-android and examples-java.
## Summary
The published Kotlin API reference has rendered **0.5.0** since it was
last
generated — four releases behind `main`, which is on 0.9.0. This
regenerates it
and fixes the generator that made it impossible.
It is not a forgotten manual step. `tools/kotlin-api-docs/generate.sh`
cannot
run against any adk-kotlin newer than **v0.6.0**.
## Why it was stuck
adk-kotlin moved from Dokka **1.9.20** to **2.2.0** at **v0.7.0**, and
Dokka 2
changed three things the script depends on:
1. **The task is gone.** `dokkaHtmlMultiModule` survives only as a
disabled
stub. Against a v0.9.0 clone, `./gradlew tasks --all` lists it verbatim
as:
```
dokkaHtmlMultiModule - [⚠ V1 tasks disabled] Runs all subprojects …
```
The build fails before generating anything.
2. **The output path moved** from `build/dokka/htmlMultiModule` to
`build/dokka/html`.
3. **Root aggregation is gone.** Dokka 1 inferred the unified
multi-module site
from the subprojects; Dokka 2 requires an explicit
`dependencies { dokka(project(...)) }` block, and adk-kotlin's root
build has
none. So even with the task name fixed there is no combined site to copy
—
only a dozen disconnected per-module ones.
## What this changes
**`tools/kotlin-api-docs/generate.sh`** — the three fixes above, plus a
post-generation check that `index.html` actually renders the requested
version.
Nothing verified that before, which is exactly how a 0.5.0 site sat in
the repo
looking freshly built.
The aggregation block is injected into the throwaway clone the script
already
makes, rather than sent upstream to adk-kotlin. That keeps the whole fix
inside
adk-docs — no second repo, no second review — and makes the module list
a docs
decision rather than an SDK one.
**`docs/api-reference/kotlin/`** — regenerated at 0.9.0. 2,462 files.
## Module coverage changes, and not purely additively
Please review this part specifically; it is the only judgement call
here.
| Module | Before | After | |
|---|---|---|---|
| `core`, `a2a`, `litertlm`, `processor`, `webserver` | ✅ | ✅ |
unchanged |
| `integrations` | ❌ | ✅ | **added** |
| `testing` | ❌ | ✅ | **added** |
| `examples` | ✅ | ❌ | **dropped** |
| `firebase`, `mlkit` | ❌ | ❌ | attempted, produce nothing |
- **`integrations` matters most.** It hosts
`BigQueryAgentAnalyticsPlugin`,
which `docs/integrations/bigquery-agent-analytics.md` documents and the
API
reference has never covered.
- **`examples` is dropped** because it is sample code rather than API
surface,
and it declares a JDK 21 toolchain that fails to auto-provision and
takes the
entire build down with it. Happy to restore it if you disagree, but it
needs
the toolchain problem solved first.
- **`firebase` and `mlkit` aggregate but emit empty directories** —
Dokka 2
generates no pages for their androidMain source sets. I left them out
rather
than shipping empty modules that imply coverage that is not there.
Making them
work needs a Dokka source-set fix in adk-kotlin, so it is out of scope
here.
## Verification
- A clean run of the committed script reproduces this exact tree.
- `index.html` renders `0.9.0`, and no file under
`docs/api-reference/kotlin/`
still contains `0.5.0`.
- The one deep link into the reference —
`docs/runtime/runconfig.md:364`, into
`google-adk-kotlin-core/com.google.adk.kt.agents/-run-config/` — still
resolves.
- The GA tag is injected exactly once per page. Eight files are skipped:
the
`navigation.html` fragments, which have no `<head>` to inject into.
- No temp-clone paths leaked into the generated HTML.
Built with **JDK 26** and Android SDK **platform 34**. adk-kotlin
declares a JDK
17 toolchain, but Dokka never needed to launch it for the aggregated
modules.
## Reviewing 2,462 files
Almost all of it is generated HTML. The only hand-written change is
`tools/kotlin-api-docs/generate.sh` (+57/-13); everything else is Dokka
output.
Reviewing the script and spot-checking a couple of rendered pages is the
useful
version of this review.
## Relationship to #2152#2152 pins adk-docs to adk-kotlin 1.0.0 and lists regenerating this
reference on
its pre-merge checklist, blocked on a `v1.0.0` tag that does not exist
yet.
This PR deliberately does **not** wait for that. Doing it at 0.9.0 now
clears
four releases of staleness immediately and proves the toolchain works
while
there is no deadline, instead of discovering the generator is broken on
release
day. Once 1.0.0 ships, #2152 re-runs the same script with a different
argument.
The site rendered one language under two names. Tab labels were split
137 `TypeScript` / 53 `Typescript`, with three pages carrying both
spellings at once (custom-agents.md 7/7, patterns.md 1/7,
function-tools.md 4/1), and the language-support badges were split 67/18
the same way. Because pymdownx.tabbed slugifies tab labels to lowercase,
both variants rendered and linked fine, so no link check or build warning
ever flagged it -- it was visible only to readers, as two names for one
SDK.
Every user-visible occurrence is normalized to `TypeScript`, plus the two
inconsistencies that turned up while doing it. 80 changed lines, accounted
for exactly:
53 tab label === "Typescript" -> === "TypeScript"
18 badge span lst-typescript">Typescript -> TypeScript
3 prose mention cloud-run.md, mcp-tools.md, workflows/patterns.md
2 api-reference/index.md card heading and link text
1 badge div attr title="...Python and Typescript."
1 mkdocs.yml nav Typescript ADK -> TypeScript ADK
1 code fence ```javascript -> ```typescript on a .ts include
1 artifacts/index.md closing summary sentence
---
80
The first six rows are pure casing: 78 lines that differ from their
originals by nothing but `Typescript` -> `TypeScript`. The last two are
not, and are the reason this is not a `sed`:
llm-agents.md:872 fenced `--8<-- ".../capital_agent.ts"` as ```javascript.
It was the only javascript-fenced `.ts` include in docs/ (the other 189
TypeScript fences are correct), and it cost that one snippet its
TypeScript highlighting.
artifacts/index.md:1084 closed the page by naming languages and got the
list wrong. It described reaching the artifact methods "using Python's
context objects or directly interacting with the `BaseArtifactService` in
Java" -- a two-language enumeration at the end of a page that carries
Python, TypeScript, Go, Java and Kotlin tabs (11/10/10/10/11), and one
that contradicts :556, which correctly names four of them. The
enumeration is dropped rather than extended: the sentence now describes
the two ways to reach these methods -- through the context object, or
through `BaseArtifactService` -- which is what the page actually teaches
and does not rot when a sixth language is added.
docs/api-reference/index.md is included even though the rest of
docs/api-reference/ is generated output that must not be touched. That
tree holds 3,140 generated HTML files and exactly one hand-authored page:
this one. It is Markdown, it is the only api-reference entry mkdocs.yml
lists as `.md` rather than `index.html` (:272, :441), it uses Material
`grid cards` and `:fontawesome-*:` shortcodes, and it carries a
`CONTRIBUTORS:` note citing issues #1716 and #1717. Its TypeScript card
already said "TypeScript" twice in its body text while its heading and
link text said "Typescript"; those two are now consistent with the body.
No generated file is modified.
Not in this change: the broken `SseConnectionParams` sample in
mcp-tools.md (docs-ts/p6c-mcp-ts-sample) and the `@google/adk` example
version bumps (docs-ts/p6b-example-versions). Only the casing of the
prose line above that sample is touched here.
Verified: `mkdocs build` exits 0 with an empty warning set on both main
and this branch, and the two warning sets are identical. A rendered
before/after diff of the whole site shows every `__tabbed_*` id, every
tab radio id and every heading anchor unchanged. Zero `=== "Typescript"`
and zero `lst-typescript">Typescript` remain anywhere in the repo.
