Issue installing OpenNLP 1.8.3

I've been trying to figure out how to install OpenNLP by myself for a while now.

I have installed Maven, added it to PATH and am able to run mvn -v with the expected result.

Now I found this question, tried the same command and got the same error. As the accepted answer on it states the Command should be used in the /Users/[my_name]/apache-opennlp-1.5.2/opennlp folder, I went to look for that folder but it's not there. This is how my apache-opennlp-1.8.3 folder looks from a fresh Download:

Running mvn clean install in this folder yields the following result:

If someone could help installing OpenNLP on Windows 10 I'd be insanely happy as everything I was looking for on Google didn't help me out. I also took a look at this question which also didn't help clearing it up for me.

you downloaded the pre-compiled version of OpenNLP 1.8.3. If you look in the bin directory, you will see a file "opennlp.bat" and "opennlp". On windows, you want to run opennlp.bat, almost everyone else should run opennlp.
