How to write Gradle plugins (in Kotlin)
summary
Explains how to implement a real Gradle plugin in Kotlin: creates an extension with enabled and dirs properties, registers a task class with @TaskAction and @OutputFile/@InputFiles annotations, uses Gradle TestKit for functional tests, and wires an always-running helper task to generate a stable input file so up-to-date checks and the build cache work. Example plugin reads and counts lines from given file paths, produces an output file, and demonstrates caching against a local build cache.
