site-maven-plugin uses incorrect email address

[ctubbsii]

I noticed that when using site-maven-plugin to update gh-pages, it publishes using an Author and Committer email address that is the first one listed in my GitHub account, but not the one set as the "default" email address. The email it is using is not configured anywhere in my Maven or Git settings locally, and there does not seem to be a way to configure the email used for a particular OAuth token in GitHub.com.
