    siteInfo {
        websiteUrl = "https://gradle.org"
        vcsUrl = "https://github.com/gradle/gradle-site-plugin"
    }

First, introduce a new data object for managing the properties `websiteUrl` and `vcsUrl`:

.SiteInfo.java
[source,java]
----
include::{snippetsPath}/developingPlugins/pluginExtension/groovy/buildSrc/src/main/java/org/myorg/SiteInfo.java[tags=snippet]
----

In the extension, create an instance of the `siteInfo` class and a method to delegate the captured values to the data instance.
