Can't Build and deploy the application server

[AreegSamir18]

I pulled the benchmark from Github, and I tried run 'mvn package' command however I keep getting the following error. I tried to modify the pom but it doesn't work. I run maven on the server folder itself but it doesn't work. What is the reason behind this error?

This is a version adapted for the CloudTM project. The project ended almost 6 years ago.
It looks like the maven repository server has been shutdown.
