- ## Method Details

  - ### getDescription

    Property<String> getDescription()
    A description for the dependencies model, which will be used in the generated sources as documentation.
    Returns:
      the description for this model
    Since:
      7.0

  - ### from

    void from(Object dependencyNotation)
    Configures the model by reading it from a version catalog. A version catalog is a component published using the `version-catalog` plugin or a local TOML file.

    This function can be called only once, further calls will result in an error. The passed notation should conform these constraints:

    - If a file notation is passed, it should be a single file.
    - If it's a resolvable dependency, it should resolve to a single file.

    If the notation doesn't conform these constraints, an exception will be thrown at configuration time.

    Parameters:
      `dependencyNotation` - any notation supported by `DependencyHandler`
    Since:
      7.0

  - ### version

    String version(String alias, Action<? super MutableVersionConstraint> versionSpec)
    Configures a dependency version which can then be referenced using the `VersionCatalogBuilder.LibraryAliasBuilder.versionRef(String)` )} method.
    Parameters:
      `alias` - an identifier for the version
      `versionSpec` - the dependency version spec
    Returns:
      the version alias name
    Since:
      7.0

  - ### version

    String version(String alias, String version)
    Configures a dependency version which can then be referenced using the `VersionCatalogBuilder.LibraryAliasBuilder.versionRef(String)` method.
    Parameters:
      `alias` - an identifier for the version
      `version` - the version alias name
    Since:
      7.0

  - ### library

    VersionCatalogBuilder.LibraryAliasBuilder library(String alias, String group, String artifact)
    Entry point for registering a library alias.
    Parameters:
      `alias` - the alias of the library
      `group` - the group of the library
      `artifact` - the artifact ID of the library
    Returns:
      a builder for this alias, to finish the version configuration
    Since:
      7.4

  - ### library

    void library(String alias, String groupArtifactVersion)
    Declare a library alias in full. This does not return a builder, as the declaration is fully complete. Use `library(String, String, String)` if you need a more complex version declaration.

    Note that declaring a classifier or extension using this method is not possible.

    Parameters:
      `alias` - the alias of the library
      `groupArtifactVersion` - the `group:artifact:version` string, all components are required
    Since:
      7.4

  - ### plugin

    VersionCatalogBuilder.PluginAliasBuilder plugin(String alias, String id)
    Entry point for registering a plugin alias.
    Parameters:
      `alias` - the alias of the plugin
      `id` - the ID of the plugin
    Returns:
      a builder for this alias, to finish the version configuration
    Since:
      7.4

  - ### bundle

    void bundle(String alias, List<String> aliases)
    Declares a bundle of dependencies. A bundle consists of a name for the bundle, and a list of aliases. The aliases must correspond to aliases defined via the `library()` methods.
    Parameters:
      `alias` - the alias of the bundle
      `aliases` - the aliases of the dependencies included in the bundle
    Since:
      7.0

      - `library(String, String, String)`
      - `library(String, String)`

  - ### getLibrariesExtensionName

    String getLibrariesExtensionName()
    Returns the name of the extension configured by this builder
    Since:
      7.0
