# CI Pipeline Configuration

## Open & import the project

In your IDEA, `File` - `Open`, select `.teamcity/pom.xml`, `import as project`, and you'll have a Maven project.

## Project structure

Mostly a standard Maven project structure. The entry point `settings.kts` defines the TeamCity project.

There are 3 subprojects in the TeamCity project hierarchy: `Check` for Gradle builds, `Promotion` for releasing Gradle versions, `Util` for miscellaneous utilities.

    public VagrantExtension(Project project) {
        this.box = project.getObjects().property(String.class);
        this.hostEnv = project.getObjects().mapProperty(String.class, Object.class);
        this.vmEnv = project.getObjects().mapProperty(String.class, Object.class);
        this.vagrantfile = project.getObjects().fileProperty();

## 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`
