## Quick Start

See [Build execution model](build-execution-model.md) for more details.

### Build state model

As Gradle executes, it acts on various pieces of the build definition, such as each project in the build.
Gradle tracks the state of each piece and transitions each piece through its lifecycle as the build runs.

 * <h3>Goals</h3>

 *   <li>{@link org.apache.maven.cling.invoker.mvnup.goals.Check} - Analyzes projects and reports needed upgrades</li>
 *   <li>{@link org.apache.maven.cling.invoker.mvnup.goals.Apply} - Applies upgrades to project files</li>
 *   <li>{@link org.apache.maven.cling.invoker.mvnup.goals.Help} - Displays usage information</li>
