Review Comment:
@pan3793 thank you for your review! The single-line command in the "Maven
build goals" list is restored and moved the details into a new "Special
plugins: JaCoCo code coverage" section right after the OWASP dependency-check
section.

> Currently Hadoop is using maven-clover2-plugin for code coverage, which is
> outdated. And Atlassian open-sourced clover last year so license cannot be
> purchased although we can switch to use the license-free version called
> "openclover".
> This Jira is to replace clover with Jacoco, which is actively maintained by
> the community.
