【Error】Maven Install Error

Dear 


I am setting up an environment to evaluate Appian RPA, referring to the URL below.
https://docs.appian.com/suite/help/22.4/rpa-8.3/custom_code/configurator.html


I have a question.
I clicked the button "download" to install Maven,but an error message popped up.



Could you tell me what prevented me from installing Maven?
Thank you.
