The `descriptor` property can also be used to add additional custom elements as children of the `<info>` element, like so:

.customizing the publication identity

 * </p><p>
 * In addition, {@link IvyModuleDescriptorSpec} provides configuration methods to customize licenses, authors, and the description to be published in the Ivy module descriptor.
 * </p><p>
 * For any other tweaks to the publication, it is possible to modify the generated Ivy descriptor file prior to publication. This is done using

import org.gradle.api.publish.ivy.IvyArtifact;
import org.gradle.api.publish.ivy.IvyConfiguration;
import org.gradle.api.publish.ivy.IvyConfigurationContainer;
import org.gradle.api.publish.ivy.IvyModuleDescriptorSpec;
import org.gradle.api.publish.ivy.internal.artifact.DefaultIvyArtifactSet;
import org.gradle.api.publish.ivy.internal.artifact.DerivedIvyArtifact;
import org.gradle.api.publish.ivy.internal.artifact.IvyArtifactInternal;

            </tr>
            <tr>
                <td>org.gradle.api.publish.ivy.IvyArtifactSet</td>
            </tr>
            <tr>
                <td>org.gradle.api.publish.ivy.IvyModuleDescriptorSpec</td>
            </tr>
            <tr>
                <td>org.gradle.api.publish.ivy.IvyModuleDescriptorAuthor</td>
            </tr>
            <tr>

You can replicate the default Ivy behavior by using the https://plugins.gradle.org/plugin/nebula.ivy-resolved-dependencies[Nebula Ivy Resolved Plugin].
Alternatively, you can link:{groovyDslPath}/org.gradle.api.publish.ivy.IvyModuleDescriptorSpec.html#org.gradle.api.publish.ivy.IvyModuleDescriptorSpec:withXml(org.gradle.api.Action)[customize the descriptor file] so that it contains the versions you want.
