@wing328 Bug installing the generator after a recursive clone

Description

after cloning the repository with a recursive clone using the command: git clone --recursive https://github.com/OpenApiTools/OpenApi-Generator.git

and then attempting to install the master branch using

mvn install

5 tests fail as follows:

I'm trying to install the generator so that I can contribute to various C# issues.

Either I am missing something when cloning/installing the project, or there appears to be an error in one or more of the tests shown above. I'm cloning on windows and have tried with/without admin privelliges.
