## 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".

    // The superclass implementation requires APIs not available until API 25+.
    if (Build.VERSION.SDK_INT <= 24) return listOf()
    return super.getHandshakeServerNames(sslSocket)
  }

  override fun log(
    message: String,
    level: Int,

Here's a little bit of that history.

## Alternatives { #alternatives }

I have been creating APIs with complex requirements for several years (Machine Learning, distributed systems, asynchronous jobs, NoSQL databases, etc), leading several teams of developers.

As part of that, I needed to investigate, test and use many alternatives.
