[feature] get rid "parallel execution" warnings

[dizzzz]

During parallel builds the following WARNINGs pop up; I'd really get rid of them as is polluting the output:

[WARNING] *****************************************************************
[WARNING] * Your build is requesting parallel execution, but this         *
[WARNING] * project contains the following plugin(s) that have goals not  *
[WARNING] * marked as thread-safe to support parallel execution.          *
[WARNING] * While this /may/ work fine, please look for plugin updates    *
[WARNING] * and/or request plugins be made thread-safe.                   *
[WARNING] * If reporting an issue, report it against the plugin in        *
[WARNING] * question, not against Apache Maven.                           *

[WARNING] *****************************************************************

solutions directions:

1. force me to ignore the messages :-)
2. find another plugin that does the same buildversion-plugin
3. re-release the plugin with the minor change ourselves

The plugin https://github.com/code54/buildversion-plugin seems to be no longer maintained. The last release was cut back in 2013!

I looked into this before a couple of years ago. I considered forking, updating (it's just missing a single annotation), and re-releasing the plugin, but... (a) It's written in Clojure, and I haven't written any Clojure in years, and (b) decompiling it into Java with Fern Flower yielded very much non-idiomatic Java code.

Even studying the de-compiled Java code, the process the plugin follows was much more complicated than I expected. As it is only a warning that is generated I abandoned the effort.

It would be cool if a suitable replacement could be identified. When I looked in the past there was nothing suitable, but maybe things have changed in the meantime?
