[VOTE] Release turbine-parent v9 based on staged repository

Hi Turbine devs,

I would like to release the Turbine parent POM, version 9.
Please verify this release candidate carefully and vote.

As this is the first git release for Turbine project, I prepared a 
documentation, where I also suggest, how to proceed before and after 
voting: 
https://cwiki.apache.org/confluence/display/TURBINE/Publishing+a+Release. 

What I suggest ist to use tags (renaming it later) and only create 
branches for a maintenance releases, if required. 


Tag: turbine-parent-9-candidate

Git repo: https://github.com/apache/turbine-parent.git

N.B. If you do a checkout for a tag, you are in detached head mode, as you 
have no branch to work on.


Artifacts:

https://repository.apache.org/content/repositories/orgapacheturbine-1067


Changes in this version include:


Fixed Bugs:
o Fix Java 11/12 javadoc-plugin bug with source flag

Changes:
o Git scm configuration settings (replacing svn)
