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.

including but not limited to: User Manual, DSL Reference and Javadoc.
This information is used to generate documentation for each Gradle version
on [docs.gradle.org](https://docs.gradle.org/).
The documentation is mostly implemented in Asciidoc
though we use GitHub-flavored Markdown for internal documentation too.

You can generate docs by running `./gradlew :docs:docs`.
