If you don't have Internet access at work, about the best you can do is download manually from someplace that does have Internet access, bring in the downloaded component(s) and install them by hand. It's less secure than if your work would let you connect directly to the Internet and a lot more time/effort/money to do that.
On the other hand, you did say "virtual machine". If it's JUST the VM and not the machine that you're running the VM on that cannot access the Internet, then perhaps you can get someone to reconfigure the VM's networking. It needs a bridge or other pass-through network connector.
Eclipse Oxygen was 2018 and support for it is probably not very good at this time. Newer versions of Eclipse no longer have names, just a release date. I think they've determined to update once every 3-4 months now and upgrading has become much simpler. If you have an Internet connection, anyway.
The secret of how to be miserable is to constantly expect things are going to happen the way that they are "supposed" to happen.
You can have faith, which carries the understanding that you may be disappointed. Then there's being a willfully-blind idiot, which virtually guarantees it.
