Add new API to retrieve name of the current module to the Resolver

[popovanton0]

ResolverImpl contains this info, but it is not exposed through the Resolver API. Maybe it is possible to enhance the API by adding moduleName property to Resolver?

Module names seem to be quite peculiar. When testing #1021, this is what I found:

Given

• a multi-project Gradle build with these subprojects

include(":annotations")
include(":workload")
include(":test-processor")

• a Kotlin multiplatform JVM/Js configuration in :workload with an extra custom clientMain source set.

This would produce the following module names:

Task	Module
:workload:kspCommonMainKotlinMetadata	<main>
:workload:kspClientMainKotlinMetadata	<main>
:workload:kspKotlinJvm	<workload>
:workload:kspKotlinJs	<dummyOutput>
:workload:kspTestKotlinJvm	<workload>

So I wonder: Are these module names of interest or is it about something else?

Any updates on this?
Or does a workaround exist to fetch the module name in the processor?

    /**
     * todo use `resolver.moduleName` when [https://github.com/google/ksp/issues/1015] is done
     * @return gradle module name
     */
    private fun moduleName(resolver: Resolver): String {
        val moduleDescriptor = resolver::class.java
            .getDeclaredField("module")
            .apply { isAccessible = true }
            .get(resolver)
        val rawName = moduleDescriptor::class.java
            .getMethod("getName")
            .invoke(moduleDescriptor)
            .toString()
        return rawName.removeSurrounding("<", ">")
    }

note that this is highly implementation dependent, might break, and will not work for the K2 implementation of KSP.
You can try to pass module name as the KSP processor options in your gradle script.
closing as resolved for now.
