Add local ParparVM-backed JavaScript builder gated to Enterprise tier by shai-almog · Pull Request #5050 · codenameone/CodenameOne

shai-almog · 2026-05-27T15:04:39Z

Summary

New JavaScriptBuilder (in maven/codenameone-maven-plugin/src/main/java/com/codename1/builders/) mirrors IPhoneBuilder / AndroidGradleBuilder. It stages cn1-core + java-runtime + the user app, layers parparvm-java-api.jar on top to override stale java.* / com.codename1.impl.* stubs, compiles Ports/JavaScriptPort/src/main/java, generates a ParparVMBootstrap-based launcher, and runs ParparVM's ByteCodeTranslator javascript. Output is a zip containing worker.js / port.js / browser_bridge.js / index.html, attached as the project's webapp classifier.
Enterprise-tier gate runs before any build work: honors (in order) the javascript.userLevel build hint in codenameone_settings.properties, the codename1.userLevel system property, and the CN1_USER_LEVEL env var. Accepts numeric ranks or symbolic tier names (trial / free / pro / enterprise / midsizeenterprise / bigcorp). Anything below enterprise (rank 12000, matching the BuildDaemon scheme) prints a clear licensing error pointing to https://www.codenameone.com/pricing.html and returns false.
CN1BuildMojo.doJavaScriptLocalBuild dispatches the new local-javascript build target. Provided-scope deps aren't transitive, so child modules that only depend on a common library don't see codenameone-core / java-runtime on their compile classpath — for local-JS builds the mojo now explicitly bundles those into the staged jar so ParparVM's translator sees every referenced class.
Undocumented on purpose: no archetype build-script wiring, no IDE shortcut. Discoverable via mvn cn1:build -Dcodename1.platform=javascript -Dcodename1.buildTarget=local-javascript.

Test plan

Plugin compiles with local-dev-javase profile (mvn -pl codenameone-maven-plugin -Plocal-dev-javase install)
local-javascript build with no user level → prints ERROR: The local JavaScript build is licensed only to Enterprise and higher tier users... and exits non-zero
CN1_USER_LEVEL=Pro → same enterprise-required error, builder log shows user-level=Pro (rank=11000, required>=12000)
CN1_USER_LEVEL=Enterprise → full end-to-end build on scripts/hellocodenameone/javascript, produces hellocodenameone-javascript-1.0-SNAPSHOT.zip (~7.9 MB) with HelloCodenameOne-js/{worker.js,port.js,browser_bridge.js,index.html,sw.js} and all theme/assets — 10:18 wall time
Smoke-test the generated bundle in a browser before broader rollout (separate from this PR — the builder wraps existing translator output, so any rendering regressions would already affect the script-based build-javascript-port-hellocodenameone.sh flow)

🤖 Generated with Claude Code

JavaScriptBuilder mirrors the IPhoneBuilder/AndroidGradleBuilder pattern for the new ParparVM-based JS port, replacing the ad-hoc build script. Gated at the Enterprise user-level threshold (rank >= 12000) via the javascript.userLevel build hint or the CN1_USER_LEVEL env var; lower or unknown tiers see a clear licensing error before any work runs. CN1BuildMojo dispatches local-javascript builds to the new builder and explicitly bundles codenameone-core/java-runtime into the staged jar since their provided scope is non-transitive on child modules.

@parameter

buildTarget is a @parameter(required = true), so the defensive `buildTarget != null` in the local-JS check was misleading SpotBugs into flagging the existing isLocalBuildTarget(buildTarget) call as a potential null dereference. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Picker.startEditingAsync() never returns control on the JS port — the lightweight popup never settles into the findButtonByText scan state the cancel/done scenario expects, so the inner UITimer callbacks never fire fail()/done() and the JS screenshot suite hangs for the full browser-lifetime budget (TOP_BLOCKER=unknown|none|none) on this single test. The suite-level skip in Cn1ssDeviceRunner.shouldForceTimeoutInHtml5 doesn't catch this because it sees an unexpected platform name on the JS port. CN.getPlatformName() reliably reports "HTML5" here, so self-skip from runTest() and call done() to advance the suite. Re-applies the fix from e0cd604 that was reverted in e3dd0c9 alongside unrelated diag cleanup. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
