From 6e61bbba2a78b169d143743c097697e2881599da Mon Sep 17 00:00:00 2001 From: BuildEngine Bot Date: Tue, 22 Sep 2026 08:06:23 +0000 Subject: [PATCH 1/2] buildengine: scaffold Phase 1 local build engine (ECJ/Kotlinc/D8/AAPT2/zipalign/apksigner) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - BuildManager: async orchestrator (build/clean/rebuild/cancel), streams BuildLogEvent per stage - steps/: EcjCompileStep, KotlincCompileStep, D8DexStep, Aapt2Step, ApkAssembleStep, ZipAlignStep, ApkSignStep — each parses tool diagnostics into BuildError(file, line, message) for editor click-to-line - classpath/ClasspathCollector: libs/*.jar + libs/*.aar -> compile/dex classpath, with content-hash AAR exploding cache - tools/BuildToolsLocator + ToolsProvisioner: locates bundled tools under /build-tools/, first-run checksummed download of the core package (not bundled in APK, not on app-open) so no forced huge SDK download; Kotlin toolchain is a separate optional package - See buildengine/PLAN.md for full roadmap, requirement mapping, and the exact existing files (GradleBuildService, RunTasksViewModel, etc.) that Phase 3 needs to touch to wire this in. --- buildengine/PLAN.md | 107 +++++++++ buildengine/engine/build.gradle.kts | 19 ++ .../tom/rv2ide/buildengine/BuildManager.kt | 217 ++++++++++++++++++ .../classpath/ClasspathCollector.kt | 73 ++++++ .../rv2ide/buildengine/model/BuildModels.kt | 72 ++++++ .../tom/rv2ide/buildengine/steps/Aapt2Step.kt | 89 +++++++ .../buildengine/steps/ApkAssembleStep.kt | 99 ++++++++ .../tom/rv2ide/buildengine/steps/D8DexStep.kt | 52 +++++ .../buildengine/steps/EcjCompileStep.kt | 89 +++++++ .../buildengine/steps/KotlincCompileStep.kt | 84 +++++++ .../buildengine/tools/BuildToolsLocator.kt | 60 +++++ .../rv2ide/buildengine/tools/ProcessRunner.kt | 91 ++++++++ .../buildengine/tools/ToolsProvisioner.kt | 176 ++++++++++++++ settings.gradle.kts | 2 + 14 files changed, 1230 insertions(+) create mode 100644 buildengine/PLAN.md create mode 100644 buildengine/engine/build.gradle.kts create mode 100644 buildengine/engine/src/main/java/com/tom/rv2ide/buildengine/BuildManager.kt create mode 100644 buildengine/engine/src/main/java/com/tom/rv2ide/buildengine/classpath/ClasspathCollector.kt create mode 100644 buildengine/engine/src/main/java/com/tom/rv2ide/buildengine/model/BuildModels.kt create mode 100644 buildengine/engine/src/main/java/com/tom/rv2ide/buildengine/steps/Aapt2Step.kt create mode 100644 buildengine/engine/src/main/java/com/tom/rv2ide/buildengine/steps/ApkAssembleStep.kt create mode 100644 buildengine/engine/src/main/java/com/tom/rv2ide/buildengine/steps/D8DexStep.kt create mode 100644 buildengine/engine/src/main/java/com/tom/rv2ide/buildengine/steps/EcjCompileStep.kt create mode 100644 buildengine/engine/src/main/java/com/tom/rv2ide/buildengine/steps/KotlincCompileStep.kt create mode 100644 buildengine/engine/src/main/java/com/tom/rv2ide/buildengine/tools/BuildToolsLocator.kt create mode 100644 buildengine/engine/src/main/java/com/tom/rv2ide/buildengine/tools/ProcessRunner.kt create mode 100644 buildengine/engine/src/main/java/com/tom/rv2ide/buildengine/tools/ToolsProvisioner.kt diff --git a/buildengine/PLAN.md b/buildengine/PLAN.md new file mode 100644 index 000000000..e191cf06c --- /dev/null +++ b/buildengine/PLAN.md @@ -0,0 +1,107 @@ +# Local Build Engine — Roadmap (Sketchware-Pro-style, Gradle-free) + +## Status: Phase 1 scaffolded (this commit) + +`buildengine/engine/` — new module, Gradle-free at *runtime* (it's plain +Kotlin/JVM code that itself still compiles via the IDE's own Gradle build — +that's unrelated to what it builds for the user's Android project). + +Files added: +- `model/BuildModels.kt` — BuildError (file+line for editor click-to-line), + BuildStage, BuildResult, BuildLogEvent, BuildConfig +- `tools/BuildToolsLocator.kt` — resolves bundled ecj/d8/aapt2/zipalign/ + apksigner/android.jar/kotlinc under `/build-tools/` +- `tools/ProcessRunner.kt` — cancellable subprocess runner w/ line streaming +- `classpath/ClasspathCollector.kt` — libs/*.jar + libs/*.aar → compile/dex + classpath (AAR exploding with content-hash cache) +- `steps/EcjCompileStep.kt` — Java → .class, parses ECJ diagnostics +- `steps/KotlincCompileStep.kt` — Kotlin → .class (optional component) +- `steps/D8DexStep.kt` — .class + libs → classes.dex +- `steps/Aapt2Step.kt` — res/ + manifest → resources.apk (also emits R.java) +- `steps/ApkAssembleStep.kt` — merges dex+assets into the apk;
