Currently the property minimalJavaBuildVersion defaults to 1.8 (https://github.com/apache/maven-apache-parent/blob/b6149240303a5d8cd59413b1544125548e752d21/pom.xml#L99C6-L99C29).
This is not a reasonable default if property maven.compiler.target is set to something above 8.

I would propose to increase the default value of maven.compiler.target to 8 (https://github.com/apache/maven-apache-parent/blob/b6149240303a5d8cd59413b1544125548e752d21/pom.xml#L101C28-L101C29) and at the same time change the default value of minimalJavaBuildVersion to ${maven.compiler.target}.
