      • 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 resolvable 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

        Takes a closure which gets coerced into a Spec. Behaves otherwise in the same way as copyRecursive(org.gradle.api.specs.Spec)

        This method is only intended for use for specific situations involving resolvable configuration, it is NOT intended as a general-purpose copying mechanism.

        Parameters:
        dependencySpec - filtering requirements
        Returns:
        copy of this configuration
        Implementation Requirements:
        Usage: This method should only be called on resolvable 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.

      • setCanBeConsumed

        void setCanBeConsumed​(boolean allowed)
        Configures if a configuration can be consumed.
        Since:
        3.3

      • isCanBeConsumed

        boolean isCanBeConsumed()
        Returns true if this configuration can be consumed from another project, or published. Defaults to true.
        Returns:
        true if this configuration can be consumed or published.
        Since:
        3.3

      • setCanBeResolved

        void setCanBeResolved​(boolean allowed)
        Configures if a configuration can be resolved.
        Since:
        3.3

      • isCanBeResolved

        boolean isCanBeResolved()
        Returns true if it is allowed to query or resolve this configuration. Defaults to true.
        Returns:
        true if this configuration can be queried or resolved.
        Since:
        3.3

      • setCanBeDeclared

        @Incubating
void setCanBeDeclared​(boolean allowed)
        Configures if a configuration can have dependencies declared upon it.
        Since:
        8.2

      • isCanBeDeclared

        @Incubating
boolean isCanBeDeclared()
        Returns true if it is allowed to declare dependencies upon this configuration. Defaults to true.
        Returns:
        true if this configuration can have dependencies declared
        Since:
        8.2

      • shouldResolveConsistentlyWith

        @Incubating
Configuration shouldResolveConsistentlyWith​(Configuration versionsSource)
        Tells that this configuration, when resolved, should resolve versions consistently from the resolution result of another resolvable configuration. For example, it's expected that the versions of the runtime classpath are the same as the versions from the compile classpath.
        Parameters:
        versionsSource - another resolvable configuration to use as reference for versions
        Returns:
        this configuration
        Since:
        6.8
        Implementation Requirements:
        Usage: This method should only be called on resolvable configurations and will emit a deprecation warning if called on a configuration that does not permit this usage, or has had allowed this usage but marked it as deprecated.

      • disableConsistentResolution

        @Incubating
Configuration disableConsistentResolution()
        Disables consistent resolution for this configuration.
        Since:
        6.8
        Implementation Requirements:
        Usage: This method should only be called on resolvable configurations and will emit a deprecation warning if called on a configuration that does not permit this usage, or has had allowed this usage but marked it as deprecated.
