Package: org.gradle.api.artifacts

## [Java] Interface Configuration

- org.gradle.api.tasks.AntBuilderAware

- All Superinterfaces:
    Buildable, FileCollection, AntBuilderAware

  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
