## Interface MetadataSupplierAware

- All Known Subinterfaces:
    `IvyArtifactRepository`, `MavenArtifactRepository`

      public interface MetadataSupplierAware

  Interface for repositories which support custom metadata suppliers and/or version listers. A custom version lister or metadata supplier can be used as an optimization technique to avoid too many requests on a server. By providing such rules, a plugin or build author can provide the necessary information to perform component selection without having to actually fetch the component metadata on a server.

    Modifier and Type | Method | Description
    --- | --- | ---
    `void` | `setComponentVersionsLister​(Class<? extends ComponentMetadataVersionLister> lister)` | Sets a custom component versions lister.
    `void` | `setComponentVersionsLister​(Class<? extends ComponentMetadataVersionLister> lister, Action<? super ActionConfiguration> configureAction)` | Sets a custom component versions lister.
    `void` | `setMetadataSupplier​(Class<? extends ComponentMetadataSupplier> rule)` | Sets a custom metadata rule, which is capable of supplying the metadata of a component (status, status scheme, changing flag) whenever a dynamic version is requested.
    `void` | `setMetadataSupplier​(Class<? extends ComponentMetadataSupplier> rule, Action<? super ActionConfiguration> configureAction)` | Sets a custom metadata rule, possibly configuring the rule.

    - #### setMetadataSupplier

          void setMetadataSupplier​(Class<? extends ComponentMetadataSupplier> rule)

      Sets a custom metadata rule, which is capable of supplying the metadata of a component (status, status scheme, changing flag) whenever a dynamic version is requested. It can be used to provide metadata directly, instead of having to parse the Ivy descriptor.
      Parameters:
        `rule` - the class of the rule. Gradle will instantiate a new rule for each dependency which requires metadata.

    - #### setMetadataSupplier

          void setMetadataSupplier​(Class<? extends ComponentMetadataSupplier> rule,
                                   Action<? super ActionConfiguration> configureAction)

      Sets a custom metadata rule, possibly configuring the rule.
      Parameters:
        `rule` - the class of the rule. Gradle will instantiate a new rule for each dependency which requires metadata.
        `configureAction` - the action to use to configure the rule.

    - #### setComponentVersionsLister

          void setComponentVersionsLister​(Class<? extends ComponentMetadataVersionLister> lister)

      Sets a custom component versions lister. A versions lister will be called whenever a dynamic version is requested.
      Parameters:
        `lister` - the class of the lister.
      Since:

    - #### setComponentVersionsLister

          void setComponentVersionsLister​(Class<? extends ComponentMetadataVersionLister> lister,
                                          Action<? super ActionConfiguration> configureAction)

      Sets a custom component versions lister. A versions lister will be called whenever a dynamic version is requested.
      Parameters:
        `lister` - the class of the lister.
        `configureAction` - the action to use to configure the lister.
