public interface DependencySubstitution

- ## Method Summary

  Modifier and Type
  Method
  Description
  `void`
  `artifactSelection(Action<? super ArtifactSelectionDetails> action)`
  Configures the artifact selection for the substitution.
  `ComponentSelector`
  `getRequested()`
  The requested dependency, before it is resolved.
  `void`
  `useTarget(Object notation)`
  This method can be used to replace a dependency before it is resolved, e.g.
  `void`
  `useTarget(Object notation, String reason)`
  This method can be used to replace a dependency before it is resolved, e.g.

- ## Method Details

  - ### getRequested

    ComponentSelector getRequested()
    The requested dependency, before it is resolved. The requested dependency does not change even if there are multiple dependency substitution rules that manipulate the dependency metadata.

  - ### useTarget

    void useTarget(Object notation)
    This method can be used to replace a dependency before it is resolved, e.g. change group, name or version (or all three of them), or replace it with a project dependency. Accepted notations are:
    - Strings encoding group:module:version, like 'org.gradle:gradle-core:2.4'
    - Maps like [group: 'org.gradle', name: 'gradle-core', version: '2.4']
    - Project instances like `project(":api")`
    - Any instance of `ModuleComponentSelector` or `ProjectComponentSelector`
    Parameters:
      `notation` - the notation that gets parsed into an instance of `ComponentSelector`.

  - ### useTarget

    void useTarget(Object notation, String reason)
    This method can be used to replace a dependency before it is resolved, e.g. change group, name or version (or all three of them), or replace it with a project dependency and provides a human readable reason for diagnostics. Accepted notations are:
    - Strings encoding group:module:version, like 'org.gradle:gradle-core:2.4'
    - Maps like [group: 'org.gradle', name: 'gradle-core', version: '2.4']
    - Project instances like `project(":api")`
    - Any instance of `ModuleComponentSelector` or `ProjectComponentSelector`
    Parameters:
      `notation` - the notation that gets parsed into an instance of `ComponentSelector`.

  - ### artifactSelection

    void artifactSelection(Action<? super ArtifactSelectionDetails> action)
    Configures the artifact selection for the substitution. This is a convenience method which allows selecting, typically, different artifact classifiers for the same component. Artifact selection matters for components which are not published with Gradle Module Metadata and therefore do not provide proper variants to reason with.
    Parameters:
      `action` - the artifact selection configuration action
