Don't manually download the POM files. Let Maven do it. Delete any POM files you've already downloaded.

I ran the Maven command in line 1 and it worked perfectly, creating a project that I was then able to also build perfectly. So I think your manual download broke something.

I would suggest adding a archetype using the following information, it works for me fine, next step you would fix such issues, don't panic when you read "issues", they are easy to fix

Group id: co.netier
Artifcat : spring-mvc-archetype
version 1.0.2

Do you have Eclipse IDE? if yes, File -> New -> other -> type  maven project -> click next (don't forget to tune your project into eclipse workspace) -> add archetype

You may have a bigger problem.

Maven is designed specifically as an Internet application. It want to be able to download project dependencies whenever you do a Maven build request.

You do not need to be connected all the time - Maven will cache dependencies and only download them once. You do not need a direct connection - Maven can work via a proxy server. But Maven does expect to be able to pull what it needs from the Internet.

I will not say that it's impossible to run Maven without an occasional connection to the Internet, but even having a lot more experience with the internal organization of Maven than you do, I would not feel confident that I could make thing work with full reliability if I was installing everything Maven wants manually. Maven itself is the smallest part of the Maven system.

I assume you can copy files to the Linux machine, even if it doesn't have an internet connection. You can try doing a build on another machine, then copying over the entire Maven repository. You can use option -Dmaven.repo.local=/some/path to use that path as local repository, so it's contain only what you need for the project.

That is exactly where I would start. To the best of my knowledge everything in the ".m2" directory is portable unless you've hard-coded absolute paths in config files.

But of course you do have to have a live Internet connection to obtain that prototype repository. If the "offline" machine is a laptop or other portable device, I'd just take it to a public Internet access point and populate directly.
