add maven wrapper functionality to the project #86
Description
Is your feature request related to a problem? Please describe.
It is not clear which maven version is used from just looking at your project structure.
We want to remove everything, which stops people from contributing, right?
Describe the solution you'd like
Create a maven wrapper with maven command, like
"mvn -N wrapper:wrapper -Dmaven=3.8.1"
Describe alternatives you've considered
Move to gradle wrapper completely, but that would bee too much trouble.
I need to know more about the project before I start "improving" things on this level.
