This sample shows how to add a new custom source folders to the Variant for newly create source type. The source folder will not be used by any AGP tasks (since we do not know about it), however, it can be used by plugins and tasks participating into the Variant API callbacks.
In this recipe, a custom source type is registered in the app's build.gradle.kts:
androidComponents {
registerSourceType("toml")
}
To access the custom sources, you just need to use
sourceFolders.set(variant.sources.getByName("toml").getAll())
which can be used as [Task] input directly.
There are two types of SourceDirectories:
Flat and Layered.
Custom sources are always of type Flat, meaning the directories are stored in type Provider<Collection<Directory>>.
To add a folder which content will be generated during execution time by [Task], you need to use [SourceDirectories.addGeneratedSourceDirectory] and the pointer to the output folder where source files will be generated.
You can check sources assignments/manipulation at CustomPlugin
To run the recipe : ./gradlew :app:sourceSets :app:debugDisplayAllSources
and the output will show all possible source sets with source types folders:
...
release
-------
Compile configuration: releaseCompile
build.gradle name: android.sourceSets.release
Java sources: [app/src/release/java]
Kotlin sources: [app/src/release/kotlin, app/src/release/java]
Manifest file: app/src/release/AndroidManifest.xml
Android resources: [app/src/release/res]
Assets: [app/src/release/assets]
AIDL sources: [app/src/release/aidl]
RenderScript sources: [app/src/release/rs]
Baseline profile sources: [app/src/release/baselineProfiles]
JNI sources: [app/src/release/jni]
JNI libraries: [app/src/release/jniLibs]
Custom sources: [app/src/release/toml]
Java-style resources: [app/src/release/resources]
test
----
Compile configuration: testCompile
build.gradle name: android.sourceSets.test
Java sources: [app/src/test/java]
Kotlin sources: [app/src/test/kotlin, app/src/test/java]
Java-style resources: [app/src/test/resources]
...
also it will show debugDisplayAllSources output with specific toml source type folders
