Room 2.6.0-alpha02

Room Gradle Plugin This new release contains a new artifact for the Room Gradle Plugin with id androidx.room, which solves various existing issues in Room regarding having inputs and outputs of schemas via Gradle annotation processor options. The Room Gradle Plugin configures the project such that generated schemas that are consumed for auto-migrations and are output of the compile tasks are correctly configured to have reproducible and cacheable builds. The plugin offers a DSL to configure the base schema location: room { schemaDirectory("$projectDir/schemas/") } The plugin will then configure the Room compiler and the various compile tasks and its backends (javac, KAPT, KSP) to output schema files into flavored folders, i.e. schemas/flavorOneDebug/com.package.MyDatabase/1.json. As usual these files are checks-in into the repository to be used for validation and auto-migrations. Upon migrating to using the plugin instead of the annotation processor options the existing schema files must be copied to the generated flavor directories created by the plugin, this is a one-time migration operation that must be done manually. The schema documentation in developers.android.com will be updated in the future once feedback is addressed and the plugin reaches stable, so please give it a try. API Changes RoomDatabase.QueryCallback has been defined as a functional interface to allow SAM conversion usages.
