#### Custom Plugin and Task implementations

Build logic that is used across multiple subprojects should considered to be moved into a Gradle plugin with according Gradle task implmentation.
Elasticsearch specific build logic is located in the `build-tools-internal` subproject including integration tests.

- Gradle plugins and Tasks should be written in Java
- We use a groovy and spock for setting up Gradle integration tests.
