new dependency not recognised by Maven-CodePudding

The

I then tried to use xstream, but intellij couldn't resolve "XStream" even though it seems to work for JavaFX just fine. This code does not compile.

EDIT: I loaded a new project, where I used, what I believe to be, up to date versions. Maven 3.8.1, the latest intellij version, and everything else (JDK, openjfx) at version 17.0.2 yet when I try to use "XStream" in my project code (after reloading the maven project) it says "Cannot resolve symbol XStream"

Edit 2: I added junit to the dependencies, it works. I add Gson to the dependencies. It doesn't work.

I figured out that in the "modules-info.java" file, "requires xstream" is needed. That is all

One of the following may solve your problem: These are based on my previous experiences.

because may be auto import disabled. re Import maven project.(intellij: press Ctrl Shift A then actions - input "reload" find "Reload All Maven Projects").

in my experience, sometimes it does happen that the dependency is not fully received. remove xstream special version folder from .m2 (com->thoughtworks->xstream) and repeat step 1.

maybe repository not valid. check repository source in file settings.xml in .m2 (if exist) or replace to other source.

invalid cache and restart (intellij: file-> invalid caches/restart). This has solved my problem several times.

Your access to the site or repository may be closed. check network policy or use vpn (Poor probability)
