Not every module contributes to every runtime.

The core-runtime module defines each runtime:

- The target JVM for the runtime. Each runtime has its own JVM compatibility constraints.
- Some base services that are available to code hosted by the runtime. This varies by runtime.
- Additional constraints. For example, the CLI client runtimes limit the libraries that are available to the code in that runtime, for performance reasons.

// imageFsInfoProvider knows how to translate the configured runtime
// to its file system label for images.
type imageFsInfoProvider struct {
	runtimeEndpoint string
}

// ImageFsInfoLabel returns the image fs label for the configured runtime.
// For remote runtimes, it handles additional runtimes natively understood by cAdvisor.
func (i *imageFsInfoProvider) ImageFsInfoLabel() (string, error) {

While a lot of Gradle source code runs only in the Gradle daemon, not all of it does and so, when working on some source code it is important to be aware of the runtimes in which it will run.

See [Gradle runtimes](runtimes.md) for a list of these runtimes and more details.

## Build state model

As Gradle executes, it acts on various pieces of the build definition, such as each project in the build.

This platform does not provide special support for a particular kind of automation. This is the responsibility of other platforms.

It is made up of 3 architecture modules:

- **core-runtime**: Provides the runtimes or "containers" in which code runs. These runtimes include the Gradle client, the daemon and the worker processes. This is the base module on which all other architecture modules depend.
