# Interface IvyPublication

All Superinterfaces:
  `Named, Publication`

public interface IvyPublication extends Publication
An `IvyPublication` is the representation/configuration of how Gradle should publish something in Ivy format, to an Ivy repository. You directly add a named Ivy publication the project's `publishing.publications` container by providing `IvyPublication` as the type.

    publishing {
      publications {
        myPublicationName(IvyPublication) {
          // Configure the publication here
        }
      }
    }

The Ivy module identifying attributes of the publication are mapped as follows:

- `module` - `project.name`
- `organisation` - `project.group`
- `revision` - `project.version`
- `status` - `project.status`

For certain common use cases, it's often sufficient to specify the component to publish, using (`from(org.gradle.api.component.SoftwareComponent)`. The published component is used to determine which artifacts to publish, and which configurations and dependencies should be listed in the generated ivy descriptor file.

You can add configurations to the generated ivy descriptor file, by supplying a Closure to the `configurations(org.gradle.api.Action)` method.

To add additional artifacts to the set published, use the `artifact(Object)` and `artifact(Object, org.gradle.api.Action)` methods. You can also completely replace the set of published artifacts using `setArtifacts(Iterable)`. Together, these methods give you full control over the artifacts to be published.

In addition, `IvyModuleDescriptorSpec` provides configuration methods to customize licenses, authors, and the description to be published in the Ivy module descriptor.

For any other tweaks to the publication, it is possible to modify the generated Ivy descriptor file prior to publication. This is done using the `IvyModuleDescriptorSpec.withXml(org.gradle.api.Action)` method, normally via a Closure passed to the `descriptor(org.gradle.api.Action)` method.

    // Example of publishing a java component with an added source jar and custom module description
    plugins {
        id 'java'
        id 'ivy-publish'
    }

    task sourceJar(type: Jar) {
      from sourceSets.main.allJava
    }

    publishing {
      publications {
        myPublication(IvyPublication) {
          from components.java
          artifact(sourceJar) {
            type = "source"
            extension = "src.jar"
            conf = "runtime"
          }
          descriptor {
            license {
              name = "Custom License"
            }
            author {
              name = "Custom Name"
            }
            description {
              text = "Custom Description"
            }
          }
        }
      }
    }

- ## Method Details

  - ### getDescriptor

    IvyModuleDescriptorSpec getDescriptor()
    The module descriptor that will be published.
    Returns:
      The module descriptor that will be published.

  - ### descriptor

    void descriptor(Action<? super IvyModuleDescriptorSpec> configure)
    Configures the descriptor that will be published.

    The descriptor XML can be modified by using the `IvyModuleDescriptorSpec.withXml(org.gradle.api.Action)` method.

    Parameters:
      `configure` - The configuration action.

  - ### from

    void from(SoftwareComponent component)
    Provides the software component that should be published.
    - Any artifacts declared by the component will be included in the publication.
    - The dependencies declared by the component will be included in the published meta-data.
    Currently 2 types of component are supported: 'components.java' (added by the JavaPlugin) and 'components.web' (added by the WarPlugin). For any individual IvyPublication, only a single component can be provided in this way. The following example demonstrates how to publish the 'java' component to a ivy repository.

        plugins {
            id 'java'
            id 'ivy-publish'
        }

        publishing {
          publications {
            ivy(IvyPublication) {
              from components.java
            }
          }
        }

    Parameters:
      `component` - The software component to publish.

  - ### configurations

    void configurations(Action<? super IvyConfigurationContainer> config)
    Defines some `IvyConfiguration`s that should be included in the published ivy module descriptor file. The following example demonstrates how to add a "testCompile" configuration, and a "testRuntime" configuration that extends it.

        plugins {
            id 'java'
            id 'ivy-publish'
        }

        publishing {
          publications {
            ivy(IvyPublication) {
              configurations {
                  testCompile {}
                  testRuntime {
                      extend "testCompile"
                  }
              }
            }
          }
        }

    Parameters:
      `config` - An action or closure to configure the values of the constructed `IvyConfiguration`.

  - ### getConfigurations

    IvyConfigurationContainer getConfigurations()
    Returns the complete set of configurations for this publication.
    Returns:
      the configurations

  - ### artifact

    IvyArtifact artifact(Object source)
    Creates a custom `IvyArtifact` to be included in the publication. The `artifact` method can take a variety of input:
    - A `PublishArtifact` instance. Name, type, extension and classifier values are taken from the supplied instance.
    - An `AbstractArchiveTask` instance. Name, type, extension and classifier values are taken from the supplied instance.
    - Anything that can be resolved to a `File` via the `Project.file(Object)` method. Name, extension and classifier values are interpolated from the file name.
    - A `Map` that contains a 'source' entry that can be resolved as any of the other input types, including file. This map can contain additional attributes to further configure the constructed artifact.
    The following example demonstrates the addition of various custom artifacts.

        plugins {
            id 'ivy-publish'
        }

        task sourceJar(type: Jar) {
          archiveClassifier = "source"
        }

        task genDocs {
          doLast {
            // Generate 'my-docs-file.htm'
          }
        }

        publishing {
          publications {
            ivy(IvyPublication) {
              artifact sourceJar // Publish the output of the sourceJar task
              artifact 'my-file-name.jar' // Publish a file created outside of the build
              artifact source: 'my-docs-file.htm', classifier: 'docs', extension: 'html', builtBy: genDocs // Publish a file generated by the 'genDocs' task
            }
          }
        }

    Parameters:
      `source` - The source of the artifact content.

  - ### artifact

    IvyArtifact artifact(Object source, Action<? super IvyArtifact> config)
    Creates an `IvyArtifact` to be included in the publication, which is configured by the associated action. The first parameter is used to create a custom artifact and add it to the publication, as per `artifact(Object)`. The created `IvyArtifact` is then configured using the supplied action. This method also accepts the configure action as a closure argument, by type coercion.

        plugins {
            id 'ivy-publish'
        }

        task sourceJar(type: Jar) {
          archiveClassifier = "source"
        }

        task genDocs {
          doLast {
            // Generate 'my-docs-file.htm'
          }
        }

        publishing {
          publications {
            ivy(IvyPublication) {
              artifact(sourceJar) {
                // These values will be used instead of the values from the task. The task values will not be updated.
                classifier = "src"
                extension = "zip"
                conf = "runtime->default"
              }
              artifact("my-docs-file.htm") {
                type = "documentation"
                extension = "html"
                builtBy genDocs
              }
            }
          }
        }

    Parameters:
      `source` - The source of the artifact.
      `config` - An action to configure the values of the constructed `IvyArtifact`.

  - ### getArtifacts

    IvyArtifactSet getArtifacts()
    The complete set of artifacts for this publication.

    Setting this property will clear any previously added artifacts and create artifacts from the specified sources. Each supplied source is interpreted as per `artifact(Object)`. For example, to exclude the dependencies declared by a component and instead use a custom set of artifacts:

        plugins {
            id 'java'
            id 'ivy-publish'
        }

        task sourceJar(type: Jar) {
          archiveClassifier = "source"
        }

        publishing {
          publications {
            ivy(IvyPublication) {
              from components.java
              artifacts = ["my-custom-jar.jar", sourceJar]
            }
          }
        }

    Returns:
      the artifacts.

  - ### setArtifacts

    void setArtifacts(Iterable<?> sources)
    Sets the artifacts for this publication. Each supplied value is interpreted as per `artifact(Object)`.
    Parameters:
      `sources` - The set of artifacts for this publication.

  - ### getOrganisation

    String getOrganisation()
    Returns the organisation for this publication.

  - ### setOrganisation

    void setOrganisation(String organisation)
    Sets the organisation for this publication.

  - ### getModule

    String getModule()
    Returns the module for this publication.

  - ### setModule

    void setRevision(String revision)
    Sets the revision for this publication.

  - ### versionMapping

    void versionMapping(Action<? super VersionMappingStrategy> configureAction)
    Configures the version mapping strategy. For example, to use resolved versions for runtime dependencies:

        plugins {
            id 'java'
            id 'ivy-publish'
        }

        publishing {
          publications {
            maven(IvyPublication) {
              from components.java
              versionMapping {
