## Build logic organisation

The Elasticsearch project contains 3 build-related projects that are included into the Elasticsearch build as a [composite build](https://docs.gradle.org/current/userguide/composite_builds.html).

### `build-conventions`

This project contains build conventions that are applied to all elasticsearch projects.

### `build-tools`
