### Build session state

A "build session" represents a single invocation of Gradle, for example when you run `gradlew build`.
A session runs the build one or more times.
For example, when continuous build is enabled, the session may run the build many times, but when it is disabled, the session will run the build once only.

The build session state is managed by the `BuildSessionState` class.

        session.setDependencyTraverser(getDependencyTraverser());
        session.setDependencyManager(getDependencyManager());
        session.setDependencySelector(getDependencySelector());
        session.setDependencyGraphTransformer(getDependencyGraphTransformer());
        session.setArtifactTypeRegistry(getArtifactTypeRegistry());
