# Interface ArtifactHandler

public interface ArtifactHandler
This class is for defining artifacts to be published and adding them to configurations. Creating publish artifacts does not mean to create an archive. What is created is a domain object which represents a file to be published and information on how it should be published (e.g. the name).

To create an publish artifact and assign it to a configuration you can use the following syntax:

`<configurationName> <artifact-notation>, <artifact-notation> ...` or `<configurationName> <artifact-notation> { ... some code to configure the artifact }`

The notation can be one of the following types:

- `PublishArtifact`.
- `AbstractArchiveTask`. The information for publishing the artifact is extracted from the archive task (e.g. name, extension, ...). The task will be executed if the artifact is required.
- A `Provider` of `File`, `RegularFile` or `Directory`. The information for publishing the artifact is extracted from the file or directory name. When the provider represents an output of a particular task, that task will be executed if the artifact is required.
- `File`. The information for publishing the artifact is extracted from the file name.
- `Map`. The map should contain a 'file' key. This is converted to an artifact as described above. You can also specify other properties of the artifact using entries in the map.

In each case, a `ConfigurablePublishArtifact` instance is created for the artifact, to allow artifact properties to be configured. You can also override the default values for artifact properties by using a closure to configure the properties of the artifact instance

## Examples

An example showing how to associate an archive task with a configuration via the artifact handler. This way the archive can be published or referred in other projects via the configuration.

    configurations {
      //declaring new configuration that will be used to associate with artifacts
      schema
    }

    task schemaJar(type: Jar) {
      //some imaginary task that creates a jar artifact with some schema
    }

    //associating the task that produces the artifact with the configuration
    artifacts {
      //configuration name and the task:
      schema schemaJar
    }
