    - #### getModel

          <T> T getModel(Class<T> modelType)
                     throws UnknownModelException

      Fetches a snapshot of the model of the given type for the default project. The default project is generally the project referenced when a `ProjectConnection` is created.

      Any of following models types may be available, depending on the version of Gradle being used by the target build:

      - `GradleBuild`
      - `BuildEnvironment`
      - `GradleProject`
      - `IdeaProject`
      - `BasicIdeaProject`
      - `EclipseProject`
      - `HierarchicalEclipseProject`

      A build may also expose additional custom tooling models.

      Type Parameters:
        `T` - The model type.
      Parameters:
        `modelType` - The model type.
      Returns:
        The model.
      Throws:
        `UnknownModelException` - When the default project does not support the requested model.
