## 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".

One particular example is when a [method returns `null` if and only if its argument is `null`](https://github.com/gradle/gradle/blob/674b8430b024f03cae24f1e4dd6dbaa78b557dae/platforms/core-runtime/base-services/src/main/java/org/gradle/util/internal/TextUtil.java#L163).
Prefer either:
  * Provide only non-nullable version and move the `null` check to the call site (if the number of nullable callsites is low).
