Package org.gradle.api.artifacts

## Interface Configuration

- All Superinterfaces:
    `AntBuilderAware`, `Buildable`, `FileCollection`, `HasAttributes`, `HasConfigurableAttributes<Configuration>`, `Iterable<File>`

      public interface Configuration
      extends FileCollection, HasConfigurableAttributes<Configuration>

  A `Configuration` represents a group of artifacts and their dependencies. Find more information about declaring dependencies to a configuration or about managing configurations in docs for `ConfigurationContainer`

  Configuration is an instance of a `FileCollection` that contains all dependencies (see also `getAllDependencies()`) but not artifacts. If you want to refer to the artifacts declared in this configuration please use `getArtifacts()` or `getAllArtifacts()`. Read more about declaring artifacts in the configuration in docs for `ArtifactHandler` Please see the Managing Dependency Configurations User Manual chapter for more information.

      - The `Configuration` itself is resolved
      - Another `Configuration` that extends this one is resolved
      - Another `Configuration` that references this one as a project dependency is resolved
      This method is useful for specifying default dependencies for a configuration:

      - The `Configuration` itself is resolved
      - Another `Configuration` that extends this one is resolved
      - Another `Configuration` that references this one as a project dependency is resolved
      This method is useful for mutating the dependencies for a configuration:

           configurations { conf }
           configurations['conf'].withDependencies { dependencies ->
                dependencies.each { dependency ->
                    if (dependency.version == null) {
                        dependency.version { require '1.0' }
                    }
                }
           }
