Spring classpath filtering via Gradle plugin

We should be able to do that with something like:

compile("org.springframework:spring-web") {
		registerTransform {
			from.attribute(filtered, false).attribute(artifactType, "jar")
			to.attribute(filtered, true).attribute(artifactType, "jar")
			artifactTransform(FilterClasses::class.java)
		}
	}
}

// Same for spring-webflux, spring-context, spring-data-commons, etc.
class SpringFuWebFilter : ArtifactTransform() {
	
	private val classesToFilter = arrayOf(
			"org/springframework/remoting/**",
			"org/springframework/web/accept/**",
			"org/springframework/web/bind/**",
			"org/springframework/web/client/**",
			"org/springframework/web/context/**",
			"org/springframework/web/filter/**",
			"org/springframework/web/jsf/**",
			"org/springframework/web/method/**",
			"org/springframework/web/multipart/**",
		)
)

	override fun transform(input: File): List<File> {
		return if (...) listOf(input) else emptyList()
	}
}

I think GraalVM native images or Jlink are better solution to this need.

Gradle 5.5 with official support and documentation for artifact transformation has been released.
