mvn install for xsa-webapp is not working

[ArenAlyahya]

I am following this tutorial (https://www.freecodecamp.org/news/learn-kubernetes-in-under-3-hours-a-detailed-guide-to-orchestrating-containers-114ff420e882/)

I am currently stuck in step (Setting up the Spring Web Application)

I am trying to run mvn install . However, it does not produce the jar file. It gives me the following error massage. Knowing that I have JDK 8 installed and maven 3.8.2. I could not find maven 4.0.0 form Mac OS.

I am not sure what could be the problem. I found out that I should delete .m2/repo using the following command or something similar:
rm -rf rm -rf ~/.m2/repository/org/apache/

I found the solution for the issue. Maven should be installed manually rather than using brew to do that
