But you can use xml to generate an XML report and then use one of the following XSLT stylesheets to convert the report into html. Or you can write your own stylesheet.

PMD uses GitHub Actions as the CI/CD infrastructure to build and release new versions. This page gives an overview of how these workflows work and how to use them.
