[Tobjoern]

When I try to execute via ./run.sh I get the following error:

I am not sure why that is, I am new to Java development on Linux, so I might be missing something (maybe wrong version installed).
java -version outputs:

openjdk version "11.0.5" 2019-10-15

OpenJDK 64-Bit Server VM (build 11.0.5+10-post-Ubuntu-0ubuntu1.118.04, mixed mode, sharing)

mvn -version:

Help is greatly appreciated!
