~~~

However, in community doc, to build a jar,
~~~
mvn clean install -DskipTests
~~~

https://docs.optaplanner.org/7.38.0.Final/optaweb-employee-rostering-docs/html_single/index.html#buildAndRun

Actually, if you don't add "-DskipTests", the build takes long time due to test execution. So please add "-DskipTests" for product doc as well.
