A KSP implementation of AutoService.

Simply add the auto-service-ksp Gradle Plugin.

plugins {
  id("com.google.devtools.ksp") version "<version>"
  // ...
}
dependencies {
  ksp("dev.zacsweers.autoservice:auto-service-ksp:<auto-service-ksp version>")
  // NOTE: It's important that you _don't_ use compileOnly here, as it will fail to resolve at compile-time otherwise
  implementation("com.google.auto.service:auto-service-annotations:<autoservice version>")
}

Then annotate your service implementation with @AutoService as your normally would in source files.

While the AutoService annotation processor will merge existing service files, but this is not currently implemented in this KSP implementation yet.

You can customize behavior via KSP arguments. Currently there are two.

ksp {
  arg("autoserviceKsp.verify", "true")
  arg("autoserviceKsp.verbose", "true")
}

autoserviceKsp.verify enables extra validation to ensure that the annotated type does, in fact, implement the service it claims to.

autoserviceKsp.verbose enables verbose logging.

Snapshots of the development version are available in Sonatype's snapshots repository.
