compose

Composite build of Compose-jb sources

Download submodules after downloading the main project:

git submodule update --init --recursive

Set this property to always update submodules on git checkout/pull/reset:

git config --global submodule.recurse true

General requirements

• Java 11 (should be specified in JAVA_HOME)
• [macOs/Linux] Android SDK downloaded via ./scripts/downloadAndroidSdk
• [Windows] Android SDK downloaded from Android Studio and specified in ANDROID_SDK_ROOT. Required components:
  • Android 12
  • Build-Tools 30.0.3
  • NDK 21.3.6528147 (in folder $androidSdk/ndk, not in $androidSdk/ndk/$version)
  • CMake 3.10.2.4988404 (in folder $androidSdk/cmake, not in $androidSdk/cmake/$version)

Developing in IDE

1. Download Android Studio 2021.1.1 Canary 8 (https://developer.android.com/studio/archive) (it is mandatory to use exactly Canary 8!)
2. Set environment variables:

export ALLOW_PUBLIC_REPOS=1
export JAVA_TOOLS_JAR=$PWD/external/tools.jar
export ANDROIDX_PROJECTS=COMPOSE
export JAVA_HOME=<JDK_home> // it should point to Java 11 and contain /include/jvmti.h

3. Set gradle properties in ~/.gradle/gradle.properties:

androidx.compose.multiplatformEnabled=true
# note that https://android.googlesource.com/platform/frameworks/support build doesn't work with androidx.compose.jsCompilerTestsEnabled)
androidx.compose.jsCompilerTestsEnabled=true
androidx.validateProjectStructure=false

4. Open compose folder in Android Studio (not compose/frameworks/support)
5. Download a custom Gradle 7.2 and specify it in Settings -> Build, Execution, Deployment -> Build Tools -> Gradle (because Android Studio will pick the wrong Gradle in the subproject instead of the Gradle in the root project)
6. Specify Gradle JDK 11 in ... -> Build Tools -> Gradle
7. [macOs/Linux] Specify Android SDK pointed to a folder, downloaded via ./scripts/downloadAndroidSdk

Scripts

Publish artifacts to the local directory out/androidx/build/support_repo/org/jetbrains/compose:

./scripts/publish

(on Windows it doesn't build at the moment, the issue is in the line packageInspector(project, project(":compose:ui:ui-inspection") in compose/frameworks/support/compose/ui/ui/build.gradle)

Publish extended icons:

./scripts/publishExtendedIcons

Run tests for Desktop:

./scripts/testDesktop

Run tests for Web:

./scripts/testWeb
