Adding the report plugin org.apache.maven.plugins:maven-project-info-reports-plugin:3.4.2 the same error is seen, just the warning that a specific version for maven-project-info-reports-plugin should be set is gone.

Adding the maven-site-plugin:3.12.1 manually as a dependency to the POMs build section solves the error. But the "site.xml" from src/site is ignored.

I did not find the exact spot the maven-site-plugin in version 3.3.0 is added, but it should be updated to a newer version.

Also the failsafe-plugin shipped by spring-boot-parent seems to contain a dependency to maven-site-plugin version 4.0.0-M5 if I am not mistaken.

Comment From: wilkinsona

Spring Boot hasn't managed the plugin's version since 2.3.0. 3.3 is coming from Maven's defaults. You should use whatever version of the plugin and its dependencies meet your needs. If you think Maven should use a more up-to-date version by default, that suggestion should be made to the Maven maintainers.
