ComponentMetadataHandler (Gradle API 8.11.1)

Package org.gradle.api.artifacts.dsl

## Interface ComponentMetadataHandler

-     public interface ComponentMetadataHandler

  Allows the build to provide rules that modify the metadata of depended-on software components. Component metadata rules are applied in the components section of the dependencies block `DependencyHandler` of a build script. The rules can be defined in two different ways:
  1. As an action directly when they are applied in the components section
  2. As an isolated class implementing the `ComponentMetadataRule` interface

  Example shows a basic way of removing certain transitive dependencies from one of our dependencies.

       plugins {
           id 'java'
       }

       repositories {
           mavenCentral()
       }

       dependencies {
           components {
               withModule("jaxen:jaxen") {
                   allVariants {
                       withDependencies {
                           removeAll { it.group in ["dom4j", "jdom", "xerces", "maven-plugins", "xml-apis", "xom"] }
                       }
                   }

               }
           }
           implementation("jaxen:jaxen:1.1.3")
       }

- - ### Method Detail

    - #### all

          ComponentMetadataHandler all​(Action<? super ComponentMetadataDetails> rule)

      Adds a rule action that may modify the metadata of any resolved software component.
      Parameters:
        `rule` - the rule to be added
      Returns:
        this

    - #### all

          ComponentMetadataHandler all​(@DelegatesTo(ComponentMetadataDetails.class)
                                       Closure<?> rule)

      Adds a rule closure that may modify the metadata of any resolved software component.

      The supplied rule closure must declare a `ComponentMetadataDetails` as it's first parameter, allowing the component metadata to be modified.

      In addition, the rule can declare additional (read-only) parameters, which may provide extra details about the component. The order of these additional parameters is not significant.

      The following additional parameter types are supported:

      - `IvyModuleDescriptor` - additional Ivy-specific metadata. Rules declaring this parameter will only be invoked for components packaged as an Ivy module.
      - `PomModuleDescriptor` - additional Maven-specific metadata. Rules declaring this parameter will only be invoked for components packaged as a POM module.
      Parameters:
        `rule` - the rule to be added
      Returns:
        this

    - #### all

          ComponentMetadataHandler all​(java.lang.Object ruleSource)

      Adds a rule that may modify the metadata of any resolved software component.

      The ruleSource is an Object that has a single rule method annotated with `Mutate`.

      This rule method:

      - must return void.
      - must have `ComponentMetadataDetails` as the first parameter.
      - may have an additional parameter of type `IvyModuleDescriptor` or `PomModuleDescriptor`.
      Parameters:
        `ruleSource` - the rule source object to be added
      Returns:
        this

    - #### all

          ComponentMetadataHandler all​(java.lang.Class<? extends ComponentMetadataRule> rule)

      Adds a class based rule that may modify the metadata of any resolved software component.
      Parameters:
        `rule` - the rule to be added
      Returns:
        this
      Since:
        4.9

      Adds a class based rule that may modify the metadata of any resolved software component. The rule itself is configured by the provided configure action.
      Parameters:
        `rule` - the rule to be added
        `configureAction` - the rule configuration
      Returns:
        this
