An instance is created at the start of a Gradle invocation and discarded at the end of that invocation.

The build session state also includes "cross session" state that is shared with any "nested" sessions that need to be created.
This only happens when the `GradleBuild` task is used. You can mostly ignore the distinction between "cross session" and "build session" state.

### Build tree state

"Build tree" is another name for the build definition.

This platform provides specific support for Swift, C++ and C.

## Cross-cutting architecture modules

There are some additional cross-cutting architecture modules that aren't platforms:

### Enterprise integration

Provides cross-cutting integration with Gradle's commercial product.

### IDE integration

Provides cross-cutting integration with IDEs and other tooling.

### Build infrastructure

testing, publishing, and deploying software on any platform, Gradle offers a flexible model that can support the entire development lifecycle from compiling and packaging code to publishing websites. Gradle has been designed to support build automation across multiple languages and platforms, including Java, Scala, Android, Kotlin, C/C++, and Groovy, and is closely integrated with development tools and continuous integration servers, including Eclipse, IntelliJ, and Jenkins.

**For more information,...

All source code in Gradle is written to target one or more of these runtimes.
Most source code targets the daemon and the remaining code either targets a single runtime, for example the Gradle client, or is shared across multiple runtimes.

## Composition by architecture modules

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