public interface Configuration extends FileCollection, HasConfigurableAttributes<Configuration>, Named
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 Declaring Dependencies User Manual chapter for more information.

    • defaultDependencies

      Configuration defaultDependencies(Action<? super DependencySet> action)
      Execute the given action if the configuration has no defined dependencies when it first participates in dependency resolution. A Configuration will participate in dependency resolution when: This method is useful for specifying default dependencies for a configuration: 
       configurations { conf }
 configurations['conf'].defaultDependencies { dependencies ->
      dependencies.add(owner.project.dependencies.create("org.gradle:my-util:1.0"))
 }

      A Configuration is considered empty even if it extends another, non-empty Configuration.

      If multiple actions are supplied, each action will be executed until the set of dependencies is no longer empty. Remaining actions will be ignored.

      Parameters:
      action - the action to execute when the configuration has no defined dependencies.
      Returns:
      this
      Implementation Requirements:
      Usage: This method should only be called on declarable configurations and will emit a deprecation warning if called on a configuration that does not permit this usage, or has allowed this usage but marked it as deprecated.

    • withDependencies

      Configuration withDependencies(Action<? super DependencySet> action)
      Execute the given action before the configuration first participates in dependency resolution. Actions will be executed in the order provided. A configuration will participate in dependency resolution when:

      In general, this method should be avoided in favor of other lazy APIs. However, in some cases where lazy APIs are not yet available, this method can be used to perform actions before the configuration is used.

      Despite the method's name, callbacks registered on this method should not add dependencies to the configuration or mutate the dependencies already present on the configuration. Instead, use the Provider-accepting methods on DependencySet and DependencyConstraintSet.

      Consider the following example that lazily adds a dependency to a configuration: 

       configurations { conf }
 configurations['conf'].dependencies.addLater(provider {
     project.dependencies.create("com:example:1.0")
 })
      Similarly, instead of mutating an existing dependency, use dependency constraints instead. Consider the following example that uses a dependency constraint to prefer a specific version of a dependency if the dependency has not declared a preferred version itself. If the dependency has declared a version, the preferred version constraint will be ignored: 
       configurations { conf }
 dependencies {
     conf("com:example")

     constraints {
         conf("com:example") {
             version {
                 prefer("2.0")
             }
         }
     }
 }
      In some cases, using this method may still be necessary:
      • Adding excludes: This method may be used to lazily add excludes to a Configuration. Adding excludes to declared dependencies should be handled with component metadata rules
      • Mutating configuration hierarchy: Mutating a configuration's hierarchy (extendsFrom(Configuration...)) after declaration is highly discouraged. However, doing so is possible with this method.
      Parameters:
      action - a dependency action to execute before the configuration is used.
      Returns:
      this
      Since:
      4.4
