- - ### Field Detail

    - #### DEFAULT_CONFIGURATION_NAME

          public static final String DEFAULT_CONFIGURATION_NAME

      The name of the configuration that all signature artifacts will be placed into ("signatures")
      See Also:
        Constant Field Values

  - ### Constructor Detail

    - #### SigningExtension

          public SigningExtension(Project project)

      Configures the signing settings for the given project.

  - ### Method Detail

    - #### getProject

          public final Project getProject()

    - #### setRequired

          public void setRequired(Object required)

      Whether or not this task should fail if no signatory or signature type are configured at generation time. If `required` is a `Callable`, it will be stored and "called" on demand (i.e. when `isRequired()` is called) and the return value will be interpreting according to the Groovy Truth. For example:

           signing {
             required = { gradle.taskGraph.hasTask("uploadArchives") }
           }

      Because the task graph is not known until Gradle starts executing, we must use defer the decision. We can do this via using a `Closure` (which is a `Callable`). For any other type, the value will be stored and evaluated on demand according to the Groovy Truth.

           signing {
             required = false
           }

    - #### isRequired

          public boolean isRequired()

          public List<Sign> sign(Task... tasks)

      Creates signing tasks that depend on and sign the "archive" produced by the given tasks.

      The created tasks will be named "sign<input task name capitalized>". That is, given a task with the name "jar" the created task will be named "signJar".

      If the task is not an `AbstractArchiveTask`, an `InvalidUserDataException` will be thrown.

      The signature artifact for the created task is added to the `for this settings object`.

      Parameters:
        `tasks` - The tasks whose archives are to be signed
      Returns:
        the created tasks.

    - #### sign

          public List<Sign> sign(Configuration... configurations)

      Creates signing tasks that sign `all of the artifacts` of the given configurations.

      The created tasks will be named "sign<configuration name capitalized>". That is, given a configuration with the name "archives" the created task will be named "signArchives". The signature artifact for the created task is added to the `for this settings object`.

      Parameters:

    - #### sign

          public SignOperation sign(PublishArtifact... publishArtifacts)

      Digitally signs the publish artifacts, generating signature files alongside them.

      The project's default signatory and default signature type from the `signing settings` will be used to generate the signature. The returned `sign operation` gives access to the created signature files.

      If there is no configured default signatory available, the sign operation will fail.

      Parameters:
        `publishArtifacts` - The publish artifacts to sign
      Returns:
        The executed `sign operation`

    - #### sign

          public SignOperation sign(File... files)

      Digitally signs the files, generating signature files alongside them.

      The project's default signatory and default signature type from the `signing settings` will be used to generate the signature. The returned `sign operation` gives access to the created signature files.

      If there is no configured default signatory available, the sign operation will fail.

      Parameters:
        `files` - The files to sign.
      Returns:
        The executed `sign operation`.

    - #### sign

          public SignOperation sign(String classifier,
                           File... files)

      Digitally signs the files, generating signature files alongside them.

      The project's default signatory and default signature type from the `signing settings` will be used to generate the signature. The returned `sign operation` gives access to the created signature files.

      If there is no configured default signatory available, the sign operation will fail.

      Parameters:
        `classifier` - The classifier to assign to the created signature artifacts.
        `files` - The publish artifacts to sign.
      Returns:
        The executed `sign operation`.

    - #### sign

          public SignOperation sign(Closure closure)

      Creates a new `sign operation` using the given closure to configure it before executing it.

      The project's default signatory and default signature type from the `signing settings` will be used to generate the signature. The returned `sign operation` gives access to the created signature files.

      If there is no configured default signatory available (and one is not explicitly specified in this operation's configuration), the sign operation will fail.

      Parameters:
        `closure` - The configuration of the `sign operation`.
      Returns:
        The executed `sign operation`.

    - #### signPom

          public Signature signPom(MavenDeployment mavenDeployment,
                          Closure closure)

      Signs the POM artifact for the given Maven deployment.

      You can use this method to sign the generated POM when publishing to a Maven repository with the Maven plugin.

           uploadArchives { repositories { mavenDeployer {
           beforeDeployment { MavenDeployment deployment -> signing.signPom(deployment) } } } }

      You can optionally provide a configuration closure to fine tune the `sign operation` for the POM.

      If `isRequired()` is false and the signature cannot be generated (e.g. no configured signatory), this method will silently do nothing. That is, a signature for the POM file will not be uploaded.

      Parameters:
        `mavenDeployment` - The deployment to sign the POM of
        `closure` - the configuration of the underlying `sign operation` for the POM (optional)
      Returns:
        the generated signature artifact

    - #### signPom

          public Signature signPom(MavenDeployment mavenDeployment)

           uploadArchives { repositories { mavenDeployer {
           beforeDeployment { MavenDeployment deployment -> signing.signPom(deployment) } } } }

      You can optionally provide a configuration closure to fine tune the `sign operation` for the POM.

      If `isRequired()` is false and the signature cannot be generated (e.g. no configured signatory), this method will silently do nothing. That is, a signature for the POM file will not be uploaded.
