Fix errors such as "org.jetbrains.dokka.model.DClass ScrollState cannot be merged with org.jetbrains.dokka.model.DObject ScrollState" in `dokkaGeneratePublicationHtml` by Copilot · Pull Request #115 · huanshankeji/compose-multiplatform-html-unified

Copilot · 2026-03-21T09:10:48Z

Fixes ./gradlew dokkaGeneratePublicationHtml and updates the GitHub Pages deployment workflow to include Dokka-generated API documentation alongside the existing side-by-side demo.

Changes Made

Fix Dokka DClass/DObject merge error

ScrollState in jsMain: Changed actual object ScrollState → actual class ScrollState, updated rememberScrollState to return ScrollState() instead of the singleton
LazyItemScope in jsMain: Changed actual object LazyItemScope → actual class LazyItemScope, updated usages in LazyDsl.js.kt to instantiate LazyItemScope() instead of using the singleton

These fixes resolve org.jetbrains.dokka.model.DClass ScrollState cannot be merged with org.jetbrains.dokka.model.DObject ScrollState caused by expect class / actual object mismatches that Dokka cannot merge.

Update GitHub Pages deployment workflow (`demo-gh-pages.yml`)

Added dokkaGeneratePublicationHtml to the Gradle build step alongside sideBySideBrowserDistribution
Added a step to copy the Dokka HTML output (build/dokka/html/) into the deployed site under an api/ subdirectory
Updated workflow name to reflect it now deploys both the demo and API documentation

Fix `copilot-setup-steps.yml`

Changed macos-latest back to ubuntu-latest to match main

Resulting Site Structure

/ → Side-by-side demo (JS DOM + Wasm JS Canvas)
/api/ → Dokka API documentation

Verification

./gradlew :compose-multiplatform-html-unified-common:dokkaGeneratePublicationHtml passes
./gradlew dokkaGeneratePublicationHtml passes for all modules
./gradlew publishToMavenLocal passes with no compilation regressions

@copilot I have updated it to use Ubuntu in main. Try again.

Change `actual object ScrollState` to `actual class ScrollState` in jsMain to fix Dokka's inability to merge DClass and DObject models. Apply the same fix to `LazyItemScope` which had the same expect class/actual object mismatch. Reuse a single LazyItemScope instance since it's stateless.

@copilot I have updated it to use Ubuntu in main. Try again.

Fixed in 3c287b5. The dokkaGeneratePublicationHtml failure was caused by expect class / actual object mismatches that Dokka can't merge (DClass vs DObject). Changed actual object ScrollState → actual class ScrollState and actual object LazyItemScope → actual class LazyItemScope in jsMain. Both dokkaGeneratePublicationHtml (all modules) and publishToMavenLocal pass.

Done in dba83da. Updated demo-gh-pages.yml to run dokkaGeneratePublicationHtml alongside the demo build and copy the Dokka HTML output to an api/ subdirectory of the deployed site. Also fixed copilot-setup-steps.yml to use ubuntu-latest to match main.

The deployed site will have:

/api/ → Dokka API documentation
