I'm currently working on deploying a Vaadin web application project to a GlassFish 4 server using Netbeans. On my local computer (running Windows 10), I can successfully deploy the file by simply using asadmin deploy (inside glassfish/bin) on the war file associated with the project. I can also just run the project inside NetBeans.
I then proceeded to scp over the project files to an Ubuntu (v. 16.04.4) environment, and also the GlassFish files. However, when I attempted the same technique this time, and then accessed the address of the Ubuntu environment via a browser in my local computer (since my project is scheduled to run on localhost, so in this case, the local host there would be a remote domain on my local computer), there was an HTTP error (resource not found).
My first hunch (and only one due to certain following circumstances) was that I needed to rebuild the war file inside the Ubuntu environment; naturally, since I had originally build the war file by building the NetBeans project, I thought I would do the same again. I then followed the instructions here:
https://platform.netbeans.org/tutorials/nbm-maven-commandline.html
Unfortunately during Step 5 of the very first section (Creating the NetBeans Platform Application), I ran into the following error log:

So, I searched online for this issue, and I found someone with a similar issue:
Maven: Failed to retrieve plugin descriptor error
I followed the responder's solution and added in a proxy to the settings.xml file. One discrepancy, however, is that my settings.xml file was inside usr/share/maven/conf instead of .m2 (which from what I've gathered from some online searching, doesn't exist in Ubuntu); to cover my bases, I thus created a .m2 folder in the Ubuntu environment and scp'ed over all the files in my (local) .m2 folder, and then copied the settings.xml file present in usr/share/maven/conf to .m2. Here's a screenshot of the edited part in the settings.xml file:
After changing that (it was originally commented, so I just had to uncomment and fill in a few things), I tried running the netbeans setup again. However, the output was almost identical, except sometimes there were a few extra references to the proxy I used at the end of the warning messages:

The second website I found where someone had a similar issue was this:
https://communities.bmc.com/thread/160101
However, in the responder's solution, I don't even know what SDK he's referring to, and a search of the entire file system in the Ubuntu environment revealed exactly 0 occurrences of archetype-catalog.xml (via find . -name "archetype-catalog")
So, any suggestions?
EDIT: To clarify what my questions exactly are, they are the following:
1) Is my assumption correct that I can build a war locally and deploy it locally and have it work correctly, yet attempting to deploy the same war in a different address might result in erroneous behavior? More to the point, should I even worry about building the war in the Ubuntu environment? Because if not, I should probably start looking for other possible errors.
2) Why is maven not setting up Netbeans correctly EVEN AFTER adding the proxy to settings.xml?
3) Is there an Ubuntu-ized version of the solution that the person in the second website I visited (https://communities.bmc.com/thread/160101)? I.e., is there something similar to archetype-catalog that I can manipulate to solve the not-being-able-to-setup-Netbeans issue?
UPDATE: So, I think I have the answer to the first question, though I'd still like the 2nd and 3rd questions answered so I'll still leave this post as unanswered. As for the first question, I think the answer is yes. I managed to get a workaround for all my woes of using netbeans to recompile the WAR via CLI inputs; instead, I set up a VNC connection for the Ubuntu environment and was then able to access it as a GUI. From there, I simply installed Netbeans, and rebuilt the project using the GUI version of Netbeans. This was not without struggles, but after I eventually got there, I tried accessing my project from my local (Windows environment), and it worked as expected.
