## Decision

Organize the Gradle code base into a set of coarse-grained "architecture modules".
An architecture module is responsible for providing a coherent set of features and:

- Provides a set of APIs and services for use from outside the module.
- Has a private implementation.
- Is owned by a single team. A team may own multiple architecture modules.

The modules are arranged into several different "Gradle platforms".

## Composition by architecture modules

Each [architecture module and platform](platforms.md) can contribute code to any of the elements.
Not every module contributes to every element.

## Structure

Each platform and module has its own source directory under [platforms/](../platforms).
In these source directories, you will find the Gradle projects that make up the platform or module.

The platforms and modules are defined using a DSL in [settings.gradle.kts](../settings.gradle.kts)

        findLatest("junit", "junit:junit:(4.0,)", versionProperties)

This ADR does not specify the owner of this new architecture module. However, as a separate module, it can be assigned ownership independently of the other core services.

## Status

ACCEPTED

## Consequences

- Introduce the module and move the services and their implementations.
